ARNm contre la scl&#233;rose en plaques : la vraie science derri&#232;re le &#8220;71% de r&#233;mission&#8221; viral</h2><p><strong>Tu as peut-&#234;tre vu passer cette image : un chercheur australien, une th&#233;rapie ARNm, et un chiffre choc &#8212; 71% de r&#233;mission compl&#232;te chez les patients atteints de SEP. Sauf que ce chiffre n&#8217;existe dans aucune publication scientifique.</strong></p><p>J&#8217;ai v&#233;rifi&#233;. Aucun essai clinique, aucune &#233;tude peer-reviewed ne mentionne ce pourcentage. C&#8217;est du contenu viral fabriqu&#233; pour les r&#233;seaux &#8212; mais la vraie histoire derri&#232;re est en fait plus int&#233;ressante que le mensonge.</p><h3>Le m&#233;canisme r&#233;el</h3><p>Il y a deux pistes ARNm s&#233;rieuses actuellement en d&#233;veloppement pour la SEP, et elles ne font pas du tout ce que l&#8217;image pr&#233;tend.</p><p><strong>Piste 1 &#8212; Cibler le virus, pas la my&#233;line directement.</strong> Moderna d&#233;veloppe le mRNA-1195, actuellement en essai de Phase 2. Contrairement &#224; ce que sugg&#232;re l&#8217;infographie, cette th&#233;rapie ne &#8220;reprogramme&#8221; pas l&#8217;immunit&#233; contre la my&#233;line &#8212; elle vise &#224; emp&#234;cher la r&#233;activation du virus Epstein-Barr (EBV), aujourd&#8217;hui identifi&#233; comme un facteur d&#233;clencheur majeur de la SEP. Le raisonnement : si on neutralise le virus dormant, on r&#233;duit potentiellement l&#8217;activit&#233; de la maladie en amont.</p><p><strong>Piste 2 &#8212; La tol&#233;rance antig&#232;ne-sp&#233;cifique.</strong> Une approche plus proche de ce que d&#233;crit l&#8217;image existe bel et bien en recherche pr&#233;clinique : des plateformes d&#8217;ARNm encodant des prot&#233;ines de my&#233;line, con&#231;ues pour &#8220;r&#233;&#233;duquer&#8221; les cellules immunitaires &#224; tol&#233;rer la my&#233;line au lieu de l&#8217;attaquer. Les r&#233;sultats en mod&#232;les animaux d&#8217;enc&#233;phalomy&#233;lite auto-immune sont prometteurs &#8212; mais aucun essai clinique humain n&#8217;a encore &#233;t&#233; publi&#233; sur cette piste pr&#233;cise.</p><p>&#9888;&#65039; <strong>Le nuance qui compte</strong> : on parle ici d&#8217;essais de Phase 2 en cours et de recherche pr&#233;clinique &#8212; pas d&#8217;un traitement valid&#233;. La diff&#233;rence entre &#8220;r&#233;sultats encourageants en souris&#8221; et &#8220;71% de r&#233;mission chez l&#8217;humain&#8221; est immense, et c&#8217;est pr&#233;cis&#233;ment le genre d&#8217;&#233;cart que les infographies virales adorent gommer. Si la SEP te touche personnellement ou un proche, m&#233;fie-toi de toute promesse miracle non sourc&#233;e &#8212; et privil&#233;gie les sources primaires (ClinicalTrials.gov, Moderna, publications peer-reviewed).</p><h3>Mon N=1</h3><p>Je n&#8217;ai pas de SEP, donc pas de protocole personnel &#224; partager ici &#8212; mais ce sujet me rappelle pourquoi je v&#233;rifie syst&#233;matiquement chaque chiffre choc avant de vous le transmettre. Mon r&#233;flexe : d&#232;s qu&#8217;un pourcentage para&#238;t trop net (71%, 95%, &#8220;gu&#233;rison totale&#8221;), je cherche l&#8217;&#233;tude source.

plus</h2><p><strong>Et si la long&#233;vit&#233; de certaines familles n&#8217;&#233;tait pas une question de chance, mais d&#8217;un seul interrupteur g&#233;n&#233;tique mal connu ?</strong></p><p>Pr&#233;sent&#233;e le 16 juin 2026 au congr&#232;s de la Soci&#233;t&#233; Europ&#233;enne de G&#233;n&#233;tique Humaine &#224; G&#246;teborg, une &#233;tude de la Leiden Longevity Study (Pays-Bas) vient d&#8217;identifier ce qui pourrait &#234;tre l&#8217;un des m&#233;canismes les plus solides jamais trouv&#233;s derri&#232;re la long&#233;vit&#233; familiale.</p><h3>Le m&#233;canisme</h3><p>Les chercheurs ont analys&#233; le g&#233;nome de 212 familles &#8220;long&#233;vives&#8221; &#8212; des fratries de nonag&#233;naires partageant les deux m&#234;mes parents. En comparant leurs profils g&#233;n&#233;tiques &#224; des groupes contr&#244;les, ils ont identifi&#233; 4 r&#233;gions du g&#233;nome enrichies en g&#232;nes li&#233;s &#224; la long&#233;vit&#233;, ce qui a permis de r&#233;duire le champ de recherche de 20 000 &#224; 350 g&#232;nes candidats.</p><p>R&#233;sultat : 12 variants g&#233;n&#233;tiques rares associ&#233;s &#224; une meilleure sant&#233; &#224; long terme. Le plus marquant touche le g&#232;ne <strong>cGAS </strong>(cyclic GMP-AMP synthase), une prot&#233;ine qui d&#233;clenche normalement une r&#233;ponse inflammatoire quand elle d&#233;tecte de l&#8217;ADN &#8220;hors de sa place&#8221; dans la cellule &#8212; un signal d&#8217;alarme antiviral qui, avec l&#8217;&#226;ge, devient hyperactif et alimente l&#8217;inflammaging, cette inflammation chronique de bas grade qui acc&#233;l&#232;re le vieillissement de presque tous nos syst&#232;mes.</p><p>Le variant identifi&#233; rend la prot&#233;ine cGAS moins stable, donc moins r&#233;active &#8212; ce qui att&#233;nue l&#8217;activation de la voie STING en aval, sans pour autant affaiblir les d&#233;fenses immunitaires globales. R&#233;sultat concret chez les porteurs : un d&#233;clenchement des maladies cardiom&#233;taboliques (diab&#232;te de type 2, hypertension, maladies cardiovasculaires) retard&#233; d&#8217;environ <strong>13 ans</strong> par rapport aux t&#233;moins, &#224; mode de vie comparable.</p><p>&#9888;&#65039; <strong>Ce qu&#8217;il faut nuancer</strong> : ce variant est rare et n&#8217;a &#233;t&#233; identifi&#233; que dans deux familles de l&#8217;&#233;tude &#8212; on est loin d&#8217;un g&#232;ne &#8220;miracle&#8221; g&#233;n&#233;ralisable &#224; toute la population. De plus, ces r&#233;sultats ont &#233;t&#233; pr&#233;sent&#233;s en conf&#233;rence ; la publication peer-reviewed compl&#232;te et la r&#233;plication dans d&#8217;autres cohortes restent &#224; venir. Enfin, avoir ce variant ne dispense de rien : le mode de vie reste le levier le plus actionnable pour la majorit&#233; d&#8217;entre nous qui ne l&#8217;avons pas.</p><h3>Mon N=1</h3><p>Je ne peux &#233;videmment pas modifier mon g&#233;nome &#8212; mais la voie cGAS-STING peut &#234;tre influenc&#233;e par le mode de vie, notamment via la r&#233;duction du stress oxydatif et de l&#8217;ADN mitochondrial endommag&#233; en circulation (l&#8217;un des d&#233;clencheurs naturels de cGAS). Mon protocole : je&#251;ne intermittent 16:8 cinq jours par semaine, exercice en zone 2 quatre fois par semaine (pour limiter l&#8217;accumulation de d&#233;bris cellulaires), et un suivi de ma variabilit&#233; de fr&#233;quence cardiaque via mon Oura Ring comme proxy indirect de mon niveau d&#8217;inflammation syst&#233;mique. Ce n&#8217;est pas de la science dure sur cGAS sp&#233;cifiquement, mais c&#8217;est coh&#233;rent avec tout ce qu&#8217;on sait sur la r&#233;duction de l&#8217;inflammaging.</p><p><strong>&#128204; Sources</strong> : Congr&#232;s annuel de la Soci&#233;t&#233; Europ&#233;enne de G&#233;n&#233;tique Humaine, G&#246;teborg, 16 juin 2026 ; ScienceDaily, 21 juin 2026 ; Leiden University Medical Center (Prof. Eline Slagboom, P.

?</strong></p><p>On vous a d&#233;j&#224; parl&#233; du duo Dasatinib + Querc&#233;tine pour &#233;liminer les cellules s&#233;nescentes. La fisetin, elle, joue dans la m&#234;me cour &#8212; mais avec un profil beaucoup plus doux, et elle vient enfin de passer le cap des essais cliniques humains s&#233;rieux.</p><h3>Le m&#233;canisme</h3><p>La fisetin est un flavono&#239;de naturel pr&#233;sent dans les fraises (en plus forte concentration), les pommes, le raisin et l&#8217;oignon. Comme les s&#233;nolytiques de synth&#232;se, elle agit en d&#233;sactivant les voies de survie anti-apoptose qui permettent aux cellules s&#233;nescentes &#8212; ces cellules &#8220;zombies&#8221; qui ne meurent plus mais continuent de s&#233;cr&#233;ter un cocktail inflammatoire toxique (le fameux SASP) &#8212; de persister dans les tissus.</p><p>Une &#233;tude 2025 de l&#8217;Universit&#233; du Colorado Boulder a compar&#233; l&#8217;efficacit&#233; de la fisetin &#224; deux approches s&#233;nolytiques de r&#233;f&#233;rence : la suppression g&#233;n&#233;tique cibl&#233;e des cellules s&#233;nescentes (GCV) et le m&#233;dicament de synth&#232;se ABT-263. Verdict : <strong>aucune diff&#233;rence statistiquement significative</strong> entre les trois approches pour r&#233;duire la fragilit&#233; et am&#233;liorer la force de pr&#233;hension (un marqueur reconnu de long&#233;vit&#233;) chez des souris &#226;g&#233;es.</p><p>C&#244;t&#233; humain, la traduction clinique s&#8217;acc&#233;l&#232;re enfin : on compte aujourd&#8217;hui 32 essais cliniques actifs sur ClinicalTrials.gov ciblant sp&#233;cifiquement la fisetin, dont plusieurs publi&#233;s en 2025-2026 &#8212; sur la fonction vasculaire chez les seniors, la r&#233;cup&#233;ration physique chez les survivantes de cancer du sein, et la fragilit&#233; chez les personnes polypathologiques de 70 &#224; 90 ans.</p><p>&#9888;&#65039; <strong>La limite &#224; conna&#238;tre</strong> : la fisetin souffre d&#8217;une biodisponibilit&#233; tr&#232;s faible et d&#8217;un m&#233;tabolisme rapide &#8212; la dose efficace utilis&#233;e dans les essais (environ 20 mg/kg/jour pendant 2 jours cons&#233;cutifs) est largement sup&#233;rieure &#224; ce qu&#8217;on peut obtenir par l&#8217;alimentation seule. Les essais cliniques humains restent encore peu nombreux et de petite taille ; on n&#8217;a pas encore de donn&#233;es solides sur l&#8217;efficacit&#233; &#224; long terme ni sur le dosage optimal en suppl&#233;mentation chronique versus intermittente.</p><h3>Mon N=1</h3><p>Je fais des cures de fisetin en suppl&#233;mentation intermittente &#8212; deux jours cons&#233;cutifs par mois, &#224; dose &#233;lev&#233;e, plut&#244;t qu&#8217;une prise quotidienne, en suivant la logique &#8220;hit-and-run&#8221; des protocoles s&#233;nolytiques &#233;tudi&#233;s (l&#8217;id&#233;e &#233;tant d&#8217;&#233;liminer les cellules s&#233;nescentes puis de laisser le corps se r&#233;g&#233;n&#233;rer, plut&#244;t que de maintenir une exposition constante).

Et cette semaine, elle a cess&#233; d&#8217;&#234;tre philosophique.</p><p>Un premier patient humain vient de recevoir <strong>ER-100</strong>, la th&#233;rapie de reprogrammation &#233;pig&#233;n&#233;tique d&#233;velopp&#233;e par Life Biosciences &#8212; la startup cofond&#233;e par le professeur de g&#233;n&#233;tique de Harvard. Une injection unique dans l&#8217;&#339;il. Quelques semaines d&#8217;antibiotiques. Et, en th&#233;orie, des cellules qui rajeunissent.</p><div class="callout-block" data-callout="true"><p>Ce n&#8217;est pas une m&#233;taphore. C&#8217;est le premier essai clinique humain d&#8217;une th&#233;rapie anti-&#226;ge par reprogrammation cellulaire partielle jamais approuv&#233; par la FDA.</p></div><h3>Le m&#233;canisme : r&#233;&#233;crire l&#8217;&#233;pig&#233;nome, pas l&#8217;ADN</h3><p>La th&#232;se centrale de Sinclair est provocatrice : <strong>le vieillissement n&#8217;est pas caus&#233; par des dommages irr&#233;versibles &#224; l&#8217;ADN, mais par la perte progressive d&#8217;information &#233;pig&#233;n&#233;tique</strong> &#8212; autrement dit, les cellules &#8220;oublient&#8221; comment fonctionner correctement.</p><p>ER-100 tente de leur faire &#8220;se souvenir&#8221;. Le traitement introduit dans l&#8217;&#339;il via un vecteur viral trois des quatre facteurs Yamanaka &#8212; des prot&#233;ines qui, en biologie du d&#233;veloppement, permettent de reprogrammer une cellule adulte en cellule souche. La version <em>partielle</em> utilis&#233;e ici ne va pas jusqu&#8217;&#224; effacer l&#8217;identit&#233; de la cellule : elle la rajeunit sans la d&#233;diff&#233;rencier.</p><div class="callout-block" data-callout="true"><p>Le m&#233;canisme antibiotique est particuli&#232;rement &#233;l&#233;gant : les antibiotiques servent de <strong>&#8220;switch&#8221; chimique</strong> pour activer ou d&#233;sactiver les g&#232;nes th&#233;rapeutiques. Le m&#233;decin contr&#244;le ainsi la dur&#233;e et l&#8217;intensit&#233; de la reprogrammation. Une pr&#233;cision chirurgicale que les premi&#232;res g&#233;n&#233;rations de th&#233;rapies g&#233;niques ne permettaient pas.</p></div><h3>Pourquoi l&#8217;&#339;il en premier ?</h3><p>L&#8217;&#339;il est l&#8217;organe id&#233;al pour ce premier essai. Il est <strong>immunologiquement privil&#233;gi&#233;</strong> &#8212; les risques d&#8217;effets syst&#233;miques dangereux y sont bien inf&#233;rieurs &#224; ceux d&#8217;une injection dans d&#8217;autres tissus. Et les conditions cibl&#233;es sont d&#233;vastatrices :</p><p>&#8594; <strong>Glaucome</strong> : d&#233;g&#233;n&#233;rescence progressive du nerf optique, premi&#232;re cause de c&#233;cit&#233; irr&#233;versible dans le monde &#8594; <strong>NAION</strong> (<em>Neuropathie Optique Isch&#233;mique Ant&#233;rieure Non-Art&#233;ritique</em>) : un &#8220;AVC de l&#8217;&#339;il&#8221; provoquant une perte de vision soudaine et permanente, sans traitement existant &#224; ce jour</p><div class="callout-block" data-callout="true"><p><strong>Sinclair a lui-m&#234;me alert&#233; publiquement sur le lien entre les m&#233;dicaments GLP-1 (Ozempic, Wegovy) et une augmentation des cas de NAION</strong>. Les utilisateurs de ces mol&#233;cules pourraient &#234;tre deux fois plus expos&#233;s &#224; cette condition. La th&#233;rapie ER-100 pourrait donc, &#224; terme, concerner directement une partie croissante de notre communaut&#233;.</p></div><h3>Les donn&#233;es : prudence et excitation</h3><p><strong>L&#8217;essai Phase 1 porte sur moins de 20 patients</strong> &#8212; d&#8217;abord des cas de glaucome, puis des cas de NAION &#8212; recrut&#233;s &#224; Boston, New York, Los Angeles et Charleston. L&#8217;objectif principal est la s&#233;curit&#233;, pas encore l&#8217;efficacit&#233;.</p><p>Sinclair a pr&#233;alablement restaur&#233; la vision de souris dont le nerf optique avait &#233;t&#233; d&#233;lib&#233;r&#233;ment endommag&#233;. Les nerfs avaient physiquement repouss&#233;. Mais la route entre la souris et l&#8217;humain est jalonn&#233;e de d&#233;ceptions en biologie du vieillissement.</p><blockquote><p><em>&#8220;L&#8217;id&#233;e g&#233;niale ici, c&#8217;est de rajeunir la cellule pour la rendre plus r&#233;sistante aux blessures.&#8221;</em> &#8212; Dr. Joseph Rizzo, Harvard Medical School, directeur de l&#8217;&#233;tude</p></blockquote><p>&#9888;&#65039; <strong>La nuance honn&#234;te</strong> : certains chercheurs qualifient l&#8217;approche d&#8217;&#8221;extraordinairement risqu&#233;e&#8221;. Le switch antibiotique &#8212; bas&#233; sur des composants g&#233;n&#233;tiques issus d&#8217;<em>E. coli</em> et du virus herp&#232;s &#8212; n&#8217;a jamais &#233;t&#233; test&#233; chez l&#8217;humain. Une r&#233;action immunitaire reste possible. Et Sinclair est r&#233;guli&#232;rement critiqu&#233; pour avoir tendance &#224; amplifier ses r&#233;sultats avant confirmation.</p><div class="callout-block" data-callout="true"><p>Cela dit : si &#231;a fonctionne, m&#234;me partiellement, c&#8217;est le tournant de la d&#233;cennie.</p></div><p><strong>Sources :</strong> <em>Nature</em> (2026) ; <em>MIT Technology Review</em>, jan. 2026 ;

m&#8217;int&#233;resse, c&#8217;est le <strong>principe</strong> : si la reprogrammation &#233;pig&#233;n&#233;tique partielle fonctionne dans l&#8217;&#339;il, les implications pour d&#8217;autres tissus (cerveau, c&#339;ur, muscle) seront immenses. </p><p>En attendant, ma strat&#233;gie personnelle reste centr&#233;e sur la <strong>protection &#233;pig&#233;n&#233;tique</strong> : je&#251;ne intermittent 16:8, exercice d&#8217;intensit&#233; variable, sommeil deep-first via mon Oura Ring, et minimisation des perturbateurs &#233;pig&#233;n&#233;tiques connus (alcool, tabac, stress chronique, ultra-transform&#233;s). </p><p>On ne reprogramme pas encore les cellules humaines &#224; la demande &#8212; mais on peut &#233;viter de les corrompre plus vite qu&#8217;elles ne le

ans</h2><blockquote><p>Tu surveilles ta glyc&#233;mie, ton HRV, tes mitochondries. Mais as-tu v&#233;rifi&#233; ton taux de cadmium ?</p></blockquote><p>Il y a une menace silencieuse dans ton bol de riz complet, tes graines de tournesol, ton chocolat noir &#224; 85 %, et potentiellement ton eau du robinet. Elle ne fait pas de bruit. Elle ne se voit pas. Et selon les donn&#233;es &#233;pid&#233;miologiques les plus solides du moment, elle pourrait &#234;tre en train de te vieillir biologiquement &#224; une vitesse que ton horloge chronologique ne refl&#232;te pas.</p><p>Son nom : <strong>le cadmium</strong>. Un m&#233;tal lourd. Et contrairement au mercure ou au plomb, il est presque absent des conversations biohacker.</p><h3>Ce que les chiffres disent &#8212; et ils sont brutaux</h3><p>Une &#233;tude sur <strong>6 700 adultes am&#233;ricains</strong> (NHANES, publi&#233;e dans l&#8217;<em>American Journal of Epidemiology</em>) a mesur&#233; les t&#233;lom&#232;res &#8212; les &#8220;capuchons&#8221; protecteurs au bout des chromosomes, marqueurs directs du vieillissement cellulaire &#8212; en fonction des taux de cadmium sanguin et urinaire.</p><p>R&#233;sultat : <strong>les personnes avec les niveaux les plus &#233;lev&#233;s de cadmium avaient des cellules biologiquement 11 ans plus vieilles</strong> que leur &#226;ge chronologique.</p><p>Une seconde &#233;tude, publi&#233;e dans <em>ScienceDirect</em> (2025), a utilis&#233; les horloges &#233;pig&#233;n&#233;tiques GrimAge &#8212; les plus pr&#233;dictives de la mortalit&#233; r&#233;elle &#8212; sur 2 530 adultes :</p><p>&#8594; <strong>Le cadmium augmente le risque de vieillissement acc&#233;l&#233;r&#233; d&#8217;un facteur 5,7 chez les femmes</strong> &#8594; <strong>Et d&#8217;un facteur 14,2 chez les hommes</strong> &#8594; Le cadmium est identifi&#233; comme <strong>le principal contributeur au vieillissement biologique acc&#233;l&#233;r&#233;</strong> parmi tous les m&#233;taux lourds &#233;tudi&#233;s</p><p>Et une m&#233;ta-analyse publi&#233;e dans <em>Exposure and Health</em> (2026) confirme : des niveaux &#233;lev&#233;s de cadmium dans le sang sont associ&#233;s &#224; une <strong>pr&#233;valence significativement plus &#233;lev&#233;e de la maladie d&#8217;Alzheimer</strong>.</p><h3>O&#249; se cache le cadmium ?</h3><p>C&#8217;est ici que &#231;a devient inconfortable pour les biohackers qui mangent &#8220;sainement&#8221; :</p><p>&#8594; <strong>Riz complet</strong> : la couche de son concentre le m&#233;tal &#8212; le riz blanc en contient moins, au prix de moins de micronutriments. Le riz d&#8217;Asie du Sud-Est (Cambodge, Tha&#239;lande) est g&#233;n&#233;ralement plus charg&#233; que le riz europ&#233;en.<br>&#8594; <strong>Graines de tournesol</strong> : hyperaccumulateur reconnu. Une consommation quotidienne importante peut faire grimper l&#8217;exposition rapidement.<br>&#8594; <strong>Lin (graines et huile)</strong> : m&#234;me famille, m&#234;me comportement. La graine est plus probl&#233;matique que l&#8217;huile. <br>&#8594; <strong>Cacao / chocolat noir</strong> : les f&#232;ves poussant sur sols volcaniques d&#8217;Am&#233;rique latine concentrent davantage le m&#233;tal. Deux carr&#233;s par jour = exposition n&#233;gligeable. Une tablette enti&#232;re quotidienne = conversation &#224; avoir. <br>&#8594; <strong>C&#233;r&#233;ales compl&#232;tes (bl&#233;, pain complet)</strong> : source sous-estim&#233;e car consomm&#233;e en grandes quantit&#233;s. <br>&#8594; <strong>Tabac</strong> : le cas extr&#234;me. Un fumeur d&#8217;un paquet par jour <strong>double sa charge corporelle en cadmium</strong> par rapport &#224; un non-fumeur &#224; alimentation identique &#8212; l&#8217;absorption pulmonaire (~50%) &#233;tant dix fois plus efficace que l&#8217;absorption digestive (~5%).</p><p>&#9888;&#65039; <strong>La nuance importante</strong> : la variabilit&#233; g&#233;ographique est consid&#233;rable. Deux pommes de terre d&#8217;apparence identique peuvent avoir des concentrations en cadmium radicalement diff&#233;rentes selon les sols o&#249; elles ont pouss&#233;. <br>Les recommandations g&#233;n&#233;riques du type &#8220;mangez moins de chocolat&#8221; ratent souvent l&#8217;essentiel.</p><h3>Le m&#233;canisme : pourquoi le cadmium vieillit-il les cellules ?</h3><p>Le cadmium agit sur plusieurs fronts simultan&#233;ment :</p><p>&#8594; Il <strong>raccourcit les t&#233;lom&#232;res</strong> en g&#233;n&#233;rant un stress oxydatif chronique <br>&#8594; Il <strong>perturbe la m&#233;thylation de l&#8217;ADN</strong> &#8212; autrement dit, il sabote directement l&#8217;&#233;pig&#233;nome <br>&#8594; Il <strong>s&#8217;accumule dans les reins pendant des d&#233;cennies</strong> (demi-vie biologique : ~30 ans) et alt&#232;re leur fonction progressivement <br>&#8594; Il <strong>interf&#232;re avec le zinc et le s&#233;l&#233;nium</strong>, deux min&#233;raux critiques pour la d&#233;fense antioxydante et la long&#233;vit&#233;</p><p><strong>Sources :</strong> <em>American Journal of Epidemiology</em> ; <em>ScienceDirect</em> (2025) ; <em>Exposure and Health</em>, 2026 ; Rapport ANSES 2026</p><h3>&#128300; Mon N=1</h3><p>J&#8217;ai fait doser mon cadmium urinaire et sanguin dans le cadre de mon bilan m&#233;taux lourds annuel &#8212; je recommande le panel <strong>oligo&#233;l&#233;ments + m&#233;taux lourds</strong> (disponible en labo sur prescription, ou via des labos fonctionnels comme Barbier ou Cerba en France). <br>Mon protocole de r&#233;duction d&#8217;exposition : je privil&#233;gie le <strong>riz blanc basmati europ&#233;en</strong> plut&#244;t que le riz complet d&#8217;Asie, je limite les graines de tournesol &#224; une poign&#233;e par semaine maximum, et j&#8217;ai supprim&#233; mon chocolat noir quotidien tout simplement. <br>Pour la ch&#233;lation naturelle : <strong>chlorelle</strong> (3 g/jour avec les repas), <strong>coriandre fra&#238;che</strong>, et apport suffisant en <strong>zinc</strong> et <strong>s&#233;l&#233;nium</strong> qui entrent en comp&#233;tition avec le cadmium

&#8220;acide gras satur&#233;&#8221;, vous pensez probablement &#224; quelque chose &#224; &#233;viter. Et si je vous disais que le premier <strong>nouvel acide gras essentiel d&#233;couvert en 90 ans</strong> &#8212; oui, depuis les om&#233;ga-3 dans les ann&#233;es 1930 &#8212; pourrait &#234;tre l&#8217;un des suppl&#233;ments de long&#233;vit&#233; les plus prometteurs de la d&#233;cennie ?</p><p>Rencontre avec le <strong>C15:0</strong>, ou acide pentad&#233;cano&#239;que.</p><h3>Qu&#8217;est-ce que le C15:0 ?</h3><p>Le C15:0 est un acide gras satur&#233; &#224; cha&#238;ne impaire &#8212; une cat&#233;gorie quasi ignor&#233;e par la nutrition classique, focalis&#233;e sur les acides gras pairs (C16:0, C18:0). On le trouve principalement dans les <strong>graisses laiti&#232;res</strong> (beurre, fromage, lait entier) et, en moindre quantit&#233;, dans certains poissons gras. Il est &#233;galement produit en petites quantit&#233;s par le microbiome intestinal &#224; partir de fibres alimentaires.</p><p>Son statut &#8220;essentiel&#8221; signifie que le corps ne peut pas en synth&#233;tiser suffisamment seul : il doit venir de l&#8217;alimentation ou d&#8217;une suppl&#233;mentation.</p><h3>Les donn&#233;es : impressionnantes sur le papier</h3><p>Dans une &#233;tude comparative publi&#233;e dans la revue <em>Nutrients</em> (2023), des chercheurs ont test&#233; le C15:0 face aux trois candidats longevity les plus &#233;tudi&#233;s : <strong>acarbose, metformine, et rapamycine</strong>.</p><p>Les r&#233;sultats sur cultures cellulaires humaines :</p><p>&#8594; Le C15:0 et la rapamycine avaient le <strong>plus grand nombre d&#8217;activit&#233;s biologiques cliniquement pertinentes</strong> <br>&#8594; Ils <strong>partageaient 24 activit&#233;s communes</strong> sur 10 syst&#232;mes cellulaires diff&#233;rents <br>&#8594; Ces activit&#233;s incluent : <strong>anti-inflammatoire, antifibrotique, anticanc&#233;reux</strong><br>&#8594; Le C15:0 <strong>active l&#8217;AMPK et inhibe mTOR</strong> &#8212; les deux piliers de la voie de long&#233;vit&#233; humaine <br>&#8594; Des &#233;tudes &#233;pid&#233;miologiques associent des niveaux plus &#233;lev&#233;s de C15:0 &#224; un risque r&#233;duit de maladies cardiovasculaires, de diab&#232;te de type 2, et de st&#233;atose h&#233;patique</p><p>&#9888;&#65039; <strong>La nuance essentielle</strong> : ces r&#233;sultats sont issus de <strong>tests sur cultures cellulaires et &#233;tudes &#233;pid&#233;miologiques</strong> &#8212; pas d&#8217;essais cliniques humains robustes sur la long&#233;vit&#233;. Les deux seuls essais cliniques men&#233;s &#224; ce jour (sur des adultes en surpoids) ont montr&#233; des effets <strong>modestes et sp&#233;cifiques &#224; certaines voies</strong> &#8212; pas de r&#233;volution spectaculaire.

La consommation de produits laitiers entiers (non all&#233;g&#233;s) est de plus en plus associ&#233;e &#224; de meilleurs marqueurs cardiom&#233;taboliques dans les &#233;tudes observationnelles &#8212; &#224; rebours des recommandations des ann&#233;es 80-90 qui diabolisaient les graisses satur&#233;es en bloc.</p><p>Le C15:0 pourrait &#234;tre l&#8217;une des mol&#233;cules actives derri&#232;re cet effet.</p><p>Pour ceux qui ne consomment pas de produits laitiers : <strong>la suppl&#233;mentation directe</strong> (sous forme de capsules de C15:0 pur) est la seule alternative s&#233;rieuse. L&#8217;alimentation v&#233;g&#233;tale n&#8217;en fournit que des traces.</p><p><strong>Sources :</strong> <em>Nutrients</em>, oct. 2023 ; <em>Journal of Nutritional Biochemistry</em>, 2025 ; <em>Hone Health Longevity Trends</em>, mars 2026</p><h3>&#128300; Mon N=1</h3><p>J&#8217;int&#232;gre le C15:0 via l&#8217;alimentation depuis 18 mois : <strong>fromage de qualit&#233; au lait cru</strong> de brebis de temps en temps, et surtout <strong>beurre de p&#226;turages</strong> (oui, j&#8217;en mange). Je n&#8217;ai pas encore bascul&#233; sur la suppl&#233;mentation pure Fatty15, car je pr&#233;f&#232;re attendre des donn&#233;es humaines ind&#233;pendantes plus solides &#8212; mais je surveille les publications de tr&#232;s pr&#232;s. Ce que je peux dire : mes marqueurs d&#8217;inflammation (CRP ultrasensible, IL-6) sont stables et bas depuis que j&#8217;ai r&#233;introduit les graisses laiti&#232;res enti&#232;res dans mon alimentation, il y a environ deux ans. Corr&#233;lation ou causalit&#233; ? Je ne peux pas le certifier.

Le r&#233;sultat est stup&#233;fiant.</p></blockquote><p>C&#8217;est l&#8217;une des exp&#233;riences les plus &#233;l&#233;gantes pr&#233;sent&#233;es &#224; <strong>Digestive Disease Week 2026</strong>, le congr&#232;s mondial de r&#233;f&#233;rence en gastroent&#233;rologie. Et elle repose sur une id&#233;e aussi simple que r&#233;volutionnaire : <em>et si on pouvait se pr&#233;server de sa propre jeunesse biologique ?</em></p><h3>L&#8217;exp&#233;rience</h3><p>&#8594; Des chercheurs pr&#233;l&#232;vent les selles de souris jeunes &#8212; leur microbiome intestinal &#224; l&#8217;&#233;tat optimal<br>&#8594; Ils les <strong>conservent et cong&#232;lent</strong> ces &#233;chantillons<br>&#8594; Lorsque les souris vieillissent, ils leur <strong>retransplantent leurs propres bact&#233;ries jeunes</strong> via une greffe de microbiote f&#233;cal (FMT)<br>&#8594; R&#233;sultat : <strong>protection significative du foie</strong>, r&#233;duction des dommages li&#233;s &#224; l&#8217;&#226;ge, et <strong>potentiellement une diminution du risque de cancer h&#233;patique</strong></p><p>Ce qui frappe : l&#8217;effet n&#8217;est pas seulement intestinal. Le microbiome rajeuni a agi <strong>sur l&#8217;ensemble de l&#8217;organisme</strong> &#8212; et en particulier sur le foie, l&#8217;organe le plus expos&#233; au vieillissement m&#233;tabolique.</p><h3>Pourquoi le foie ?</h3><p>Le foie est le premier organe &#224; recevoir les signaux chimiques produits par vos bact&#233;ries intestinales via la veine porte. Quand le microbiome vieillit &#8212; moins diversifi&#233;, plus inflammatoire &#8212; c&#8217;est le foie qui trinque en premier :</p><p>&#8594; Inflammation chronique de bas grade<br>&#8594; Accumulation de graisse h&#233;patique (st&#233;atose)<br>&#8594; Fibrose progressive<br>&#8594; Terrain propice &#224; certains cancers du foie</p><p>En restaurant un microbiome &#8220;jeune&#8221;, les chercheurs ont invers&#233; ce processus. Chez la souris. Mais les m&#233;canismes biologiques sont conserv&#233;s chez l&#8217;humain.</p><h3>Le concept qui change tout : la &#8220;biobanque de soi&#8221;</h3><p>Cette recherche ouvre une perspective fascinante &#8212; et d&#233;j&#224; explor&#233;e par quelques startups am&#233;ricaines : <strong>congeler son microbiome &#224; 25-30 ans</strong> pour se le retransplanter plus tard.</p><p>Une entreprise comme Longevity Biotech aux &#201;tats-Unis propose d&#233;j&#224; ce service. En France, la pratique n&#8217;est pas encore encadr&#233;e pour un usage pr&#233;ventif.</p><div class="callout-block" data-callout="true"><p>&#9888;&#65039; <strong>Nuance importante</strong> : nous sommes encore au stade animal. Les essais chez l&#8217;humain restent &#224; mener. Mais la plausibilit&#233; biologique est solide, et les chercheurs ont annonc&#233; vouloir lancer des essais cliniques humains dans les 18 prochains mois.</p></div><h3>Ce que vous pouvez faire maintenant</h3><p>En attendant la biobanque intestinale g&#233;n&#233;ralis&#233;e, les leviers pour <strong>pr&#233;server un microbiome jeune</strong> sont bien document&#233;s :</p><p>&#8594; <strong>Diversit&#233; alimentaire</strong> : viser 30 plantes diff&#233;rentes par semaine (l&#233;gumes, fruits, l&#233;gumineuses, graines, herbes)<br>&#8594; <strong>Aliments ferment&#233;s quotidiens</strong> : k&#233;fir, kimchi, kombucha, miso &#8212; ils maintiennent la diversit&#233; bact&#233;rienne<br>&#8594; <strong>&#201;viter les antibiotiques inutiles</strong> &#8212; chaque cure d&#233;truit durablement des souches cl&#233;s<br>&#8594; <strong>Limiter les ultra-transform&#233;s</strong> &#8212; ils appauvrissent le microbiome en quelques jours<br>&#8594; <strong>Activit&#233; physique r&#233;guli&#232;re</strong> &#8212; elle augmente la diversit&#233; microbienne de fa&#231;on ind&#233;pendante de l&#8217;alimentation</p><h3>Mon N=1</h3><p>Je vise mes 30 plantes hebdomadaires &#8212; un objectif concret que je recommande &#224; tout le monde. Et je surveille de tr&#232;s pr&#232;s les essais cliniques humains sur la FMT pr&#233;ventive. C&#8217;est le domaine de recherche qui m&#8217;enthousiasme le plus en ce moment.</p><p><em>Sources : Digestive Disease Week 2026 (DDW) &#183; ScienceDaily, mai 2026 &#183; Euronews Health, avril

Dont Parkinson, d&#233;mence, cancer du sein et infarctus. Bienvenue dans la m&#233;decine pr&#233;dictive.</p></blockquote><p>Des chercheurs de <strong>Stanford Medicine</strong> viennent de publier dans <em>Nature Medicine</em> une IA appel&#233;e <strong>SleepFM</strong> &#8212; et ses performances red&#233;finissent ce qu&#8217;on croyait possible avec les donn&#233;es de sommeil.</p><h3>Comment &#231;a fonctionne</h3><p>SleepFM a &#233;t&#233; entra&#238;n&#233;e sur <strong>pr&#232;s de 600 000 heures de donn&#233;es de sommeil</strong> issues de 35 000 patients suivis sur 25 ans au Sleep Medicine Center de Stanford. L&#8217;IA analyse les signaux physiologiques d&#8217;une seule nuit &#8212; fr&#233;quence cardiaque, respiratoire, activit&#233; c&#233;r&#233;brale, saturation en oxyg&#232;ne &#8212; et les relie &#224; des pathologies d&#233;velopp&#233;es <em>des ann&#233;es plus tard</em>.</p><blockquote><p><em>&#8220;SleepFM apprend litt&#233;ralement le langage du sommeil.&#8221;</em> &#8212; James Zou, co-chercheur principal, Stanford</p></blockquote><h3>Les chiffres qui impressionnent</h3><p>SleepFM a &#233;valu&#233; <strong>plus de 1 000 cat&#233;gories de maladies</strong>. Elle en pr&#233;dit 130 avec une pr&#233;cision cliniquement significative (C-index &#8805; 0,8, ce qui signifie que le mod&#232;le a raison 80 % du temps) :</p><p>&#8594; <strong>Parkinson</strong> : C-index <strong>0,89</strong> &#8212; la pr&#233;diction la plus pr&#233;cise<br>&#8594; <strong>D&#233;mence</strong> : 0,85<br>&#8594; <strong>Maladie cardiaque hypertensive</strong> : 0,84<br>&#8594; <strong>Cancer de la prostate</strong> : 0,89<br>&#8594; <strong>Cancer du sein</strong> : 0,87<br>&#8594; <strong>Infarctus du myocarde</strong> : 0,81<br>&#8594; <strong>Risque de d&#233;c&#232;s toutes causes</strong> : 0,84</p><p>Pour comparaison : un C-index de 0,8 est le seuil &#224; partir duquel un outil de d&#233;pistage est consid&#233;r&#233; comme cliniquement utile en m&#233;decine.</p><h3>Pourquoi le sommeil peut pr&#233;dire autant</h3><p>Le sommeil n&#8217;est pas une pause. C&#8217;est le moment o&#249; le corps :</p><p>&#8594; <strong>Consolide les souvenirs</strong> et &#233;lague les connexions neuronales inutiles<br>&#8594; <strong>Drainase le cerveau</strong> via le syst&#232;me glymphatique (les prot&#233;ines li&#233;es &#224; Alzheimer s&#8217;&#233;liminent la nuit)<br>&#8594; <strong>R&#233;gule l&#8217;immunit&#233;</strong> et la r&#233;ponse inflammatoire<br>&#8594; <strong>R&#233;pare l&#8217;ADN</strong> des cellules endommag&#233;es dans la journ&#233;e<br>&#8594; <strong>Calibre le syst&#232;me nerveux autonome</strong> &#8212; reflet direct de l&#8217;&#233;tat cardiovasculaire</p><p>Quand quelque chose ne va pas dans ces processus, les signaux apparaissent dans les donn&#233;es de sommeil <em>avant</em> que les sympt&#244;mes cliniques n&#8217;&#233;mergent. C&#8217;est exactement ce que capture SleepFM.</p><div class="callout-block" data-callout="true"><p>&#9888;&#65039; <strong>Nuance importante</strong> : SleepFM a &#233;t&#233; entra&#238;n&#233; sur des donn&#233;es de polysomnographie compl&#232;te (enregistrement en laboratoire), pas sur les donn&#233;es d&#8217;une Apple Watch. Vos wearables captent une fraction de ces signaux &#8212; mais les chercheurs travaillent d&#233;j&#224; &#224; adapter le mod&#232;le aux donn&#233;es grand public.</p></div><h3>Ce que &#231;a change pour le biohacking</h3><p>Pendant des ann&#233;es, on a optimis&#233; le sommeil pour &#234;tre plus performant le lendemain. Cette recherche change le cadre : <strong>le sommeil est une fen&#234;tre diagnostique</strong>. Ce qui se passe la nuit n&#8217;est pas seulement la cons&#233;quence de votre journ&#233;e &#8212; c&#8217;est un signal sur ce que votre corps pr&#233;pare pour les 10 prochaines ann&#233;es.</p><p>&#8594; Un score de VFC (variabilit&#233; de fr&#233;quence cardiaque) chroniquement bas la nuit n&#8217;est pas &#8220;juste du stress&#8221;<br>&#8594; Des micro-&#233;veils r&#233;p&#233;t&#233;s ne sont pas &#8220;normal avec l&#8217;&#226;ge&#8221;<br>&#8594; Une architecture de sommeil d&#233;grad&#233;e (peu de sommeil profond, peu de REM) m&#233;rite investigation</p><h3>Mon N=1</h3><p>Je traque mon sommeil depuis 6 ans avec un Oura Ring. Ce que j&#8217;en tire n&#8217;est pas un score de performance &#8212; c&#8217;est un <strong>tableau de bord biologique longitudinal</strong>. SleepFM me confirme que j&#8217;ai raison de m&#8217;y int&#233;resser s&#233;rieusement. Dans les 2 &#224; 3 ans, j&#8217;esp&#232;re voir ces outils accessibles au grand public via les wearables actuels.</p><p>Et en attendant : si votre sommeil est chroniquement perturb&#233;, ne l&#8217;acceptez pas comme une fatalit&#233;. C&#8217;est peut-&#234;tre votre corps qui vous envoie un message que vous n&#8217;avez pas encore su lire.</p><p>Une petite s&#233;ance de <a href="https://www.lebootcamp.fit/mediflow">MediFlow</a>

En France, il est r&#233;serv&#233; aux contextes de conseil g&#233;n&#233;tique ou de recherche, pas encore syst&#233;matiquement prescrit en bilan standard.

Tests g&#233;n&#233;tiques grand public</strong> Des services comme <strong>23andMe</strong> ou <strong>MyHeritage DNA</strong> incluent le typage APOE dans leurs analyses.

Et je suis arriv&#233;e au sommet... <strong>sans &#234;tre essouffl&#233;e</strong>. Tellement en forme que j&#8217;ai dans&#233; sur le sommet. Litt&#233;ralement. Idem pour le Kilimandjaro, une montagne pas technique et facile d&#8217;acc&#232;s mais tout de m&#234;me &#224; 5962m (arriv&#233;e en haut, j&#8217;ai m&#234;me couru sur le sommet).</p><p>Un VO2 Max de 34 ne danse pas &#224; 6 500 m&#232;tres. L&#8217;algorithme, lui, ne le sait pas.</p><h3>Ce que mesure vraiment un wearable</h3><p>Le VO2 Max &#8220;vrai&#8221; se mesure en laboratoire, en courant &#224; bout de souffle sur un tapis roulant, avec un masque sur le visage qui analyse vos gaz respiratoires. C&#8217;est le gold standard. C&#8217;est contraignant, co&#251;teux, et personne ne le fait tous les matins avant le caf&#233;.</p><p>Ce que fait votre montre, c&#8217;est une <strong>estimation algorithmique</strong> bas&#233;e sur : &#8594; Votre fr&#233;quence cardiaque au repos et &#224; l&#8217;effort &#8594; Votre &#226;ge, taille, poids (que vous avez saisis vous-m&#234;me) &#8594; Les donn&#233;es GPS de vos sorties (quand il y en a)</p><p>En clair : votre Garmin, votre Whoop ou votre Oura ne mesure pas votre consommation d&#8217;oxyg&#232;ne. Elle <em>devine</em>. Et pour les appareils sans GPS comme l&#8217;Oura Ring ou la Whoop &#8212; qui ne captent pas vos performances en ext&#233;rieur &#8212; l&#8217;estimation repose encore davantage sur des mod&#232;les statistiques g&#233;n&#233;raux. Mon VO2 Max &#224; 34 affich&#233; par ma Whoop en est la preuve vivante.</p><h3>Jusqu&#8217;&#224; quelle marge d&#8217;erreur ?</h3><p>Des &#233;tudes ind&#233;pendantes ont compar&#233; les estimations des wearables aux mesures en laboratoire. Les r&#233;sultats sont &#233;difiants :</p><p>&#8594; <strong>Garmin</strong> : marge d&#8217;erreur entre <strong>&#177;3 et &#177;10 points</strong> selon les mod&#232;les et profils utilisateurs <br>&#8594; <strong>Apple Watch</strong> : &#233;cart parfois sup&#233;rieur &#224; <strong>10 points</strong> chez les utilisateurs s&#233;dentaires ou en surpoids <br>&#8594; <strong>Whoop &amp; Oura</strong> : ces appareils n&#8217;ont pas de GPS et ne mesurent pas directement l&#8217;effort cardio-respiratoire en conditions r&#233;elles &#8212; leur estimation de VO2 Max est particuli&#232;rement approximative, bas&#233;e quasi exclusivement sur la FC de repos et les donn&#233;es de r&#233;cup&#233;ration</p><p>Un &#233;cart de 10 points, c&#8217;est la diff&#233;rence entre &#8220;athl&#232;te amateur bien entra&#238;n&#233;&#8221; et &#8220;s&#233;dentaire &#224; surveiller&#8221;.

Une valeur basse est associ&#233;e &#224; un risque cardiovasculaire plus &#233;lev&#233;. Mais quand un algorithme vous sort un chiffre alarmiste un lundi matin parce que vous avez mal dormi, que vous &#233;tiez stress&#233;, ou que vous avez oubli&#233; de renseigner votre nouveau poids... vous paniqiez pour rien.</p><blockquote><p><em>J&#8217;ai personnellement vu des lectrices de biohacker.fr me contacter en larmes parce que leur Apple Watch avait soudainement affich&#233; un VO2 Max en chute de 6 points en une semaine. Apr&#232;s investigation : elles avaient modifi&#233; leur poids dans l&#8217;appli.</em></p></blockquote><h3>Ce que vous devriez vraiment faire</h3><p><strong>&#8594; Utilisez votre wearable pour les tendances, pas pour les valeurs absolues.</strong> Si votre VO2 Max estim&#233; monte r&#233;guli&#232;rement sur 3-6 mois, c&#8217;est un signal positif. S&#8217;il plonge brutalement, cherchez d&#8217;abord une explication logique (maladie, manque de sommeil, changement de donn&#233;es profil) avant de paniquer. Pour ma part, 1 mois de plong&#233;es non stop en Papouasie, depuis un bateau avec z&#233;ro activit&#233; cardio ou renfo possible (premi&#232;re plong&#233;e &#224; 7h du matin, derni&#232;re plong&#233;e &#224; 20h, et 2 entre), j&#8217;avais perdu 6 points de Vo2Max.</p><p><strong>&#8594; Faites un test r&#233;el si vous voulez un chiffre fiable.</strong> Les centres de cardiologie sportive proposent des tests d&#8217;effort (CPET) &#224; partir de 80-150&#8364;. Une fois par an, c&#8217;est amplement suffisant pour calibrer ce que votre montre vous raconte.</p><p><strong>&#8594; Les marqueurs &#224; surveiller davantage que le VO2 Max :</strong></p><ul><li><p>La variabilit&#233; de la fr&#233;quence cardiaque (HRV) au r&#233;veil &#8212; plus stable, moins influenc&#233;e</p></li><li><p>La fr&#233;quence cardiaque de r&#233;cup&#233;ration apr&#232;s effort</p></li><li><p>Le temps de r&#233;cup&#233;ration entre deux s&#233;ances</p></li></ul><p><strong>Mon conseil N=1 :</strong> j&#8217;utilise une <strong>Oura Ring</strong> et une <strong>Whoop</strong> &#8212; deux des wearables les plus avanc&#233;s du march&#233;. Ma Whoop m&#8217;affiche un VO2 Max de 34. Ce qui, selon les tableaux officiels, me classerait dans la cat&#233;gorie &#8220;&#224; surveiller&#8221;.</p><p>Et voil&#224; le twist : <strong>j&#8217;ai fait le test en clinique. R&#233;sultat identique &#8212; 34.</strong> Le masque, le tapis, le labo complet. M&#234;me chiffre.</p><p>Sauf qu&#8217;en 2025, j&#8217;ai gravi une montagne de <strong>6 500 m&#232;tres</strong> en divisant par deux le temps de mont&#233;e habituel (3 heures tout pile au lieu des 6/7 habituelles). Arriv&#233;e au sommet : pas essouffl&#233;e. Tellement bien que j&#8217;ai dans&#233;.

Seuls 3 % des patients avec m&#233;tastases survivent au-del&#224; de 5 ans.

Les chercheurs la d&#233;crivaient comme une &#8220;balle graisseuse&#8221; sur laquelle aucune mol&#233;cule ne pouvait s&#8217;accrocher.

Ce n&#8217;est un secret pour personne. On lui pr&#234;te des bains de velours de cerf, une alimentation spartiate, des heures de natation quotidienne. Mais cette semaine, il a franchi un cap in&#233;dit : <strong>commander la cr&#233;ation du &#8220;premier m&#233;dicament de th&#233;rapie g&#233;nique anti-&#226;ge au monde&#8221;</strong>, avec un budget pharaonique de plus de <strong>2 000 milliards de roubles &#8212; soit 26,4 milliards de dollars</strong>.</p><blockquote><p><em>&#8220;Ce qui semblait il y a encore quelques ann&#233;es relever d&#8217;un futur incroyable est en train de devenir r&#233;alit&#233;.&#8221;</em>&#8212; Tatiana Golikova, vice-Premi&#232;re ministre russe</p></blockquote><h3>Comment &#231;a marche ?</h3><p>Le projet cible le <strong>r&#233;cepteur RAGE</strong> (<em>Receptor for Advanced Glycation End Products</em>) &#8212; un m&#233;canisme cellulaire bien document&#233; dans la litt&#233;rature scientifique, qui se d&#233;clenche lors du vieillissement. </p><p>Denis S&#233;kirinski, sous-ministre des Sciences, l&#8217;a expliqu&#233; sans ambigu&#239;t&#233; lors d&#8217;une conf&#233;rence &#224; Saransk :</p><blockquote><p><em>&#8220;Le g&#232;ne RAGE est un r&#233;cepteur dont l&#8217;activation d&#233;clenche le vieillissement de la cellule.

Production esp&#233;r&#233;e : <strong>entre 2028 et 2030</strong>.</p><h3>Mon analyse biohacker &#128269;</h3><p>Soyons lucides. Ce qu&#8217;on appelle ici &#8220;vaccin&#8221; est en r&#233;alit&#233; une <strong>th&#233;rapie g&#233;nique exp&#233;rimentale</strong>. Aucun essai humain n&#8217;a encore &#233;t&#233; conduit. La recherche sur les r&#233;cepteurs RAGE existe et est s&#233;rieuse &#8212; mais passer des mod&#232;les animaux &#224; un m&#233;dicament pr&#234;t &#224; l&#8217;emploi, c&#8217;est un chemin long et parsem&#233; d&#8217;emb&#251;ches.</p><p>Ce qui est r&#233;el, en revanche : <br>&#8594; <strong>La motivation g&#233;opolitique</strong> : l&#8217;esp&#233;rance de vie des hommes russes est de 67 ans (contre 76,5 aux &#201;tats-Unis).

une <strong>alimentation m&#233;diterran&#233;enne riche en yaourt</strong>, maintenait une activit&#233; physique et sociale intense, et vivait dans un environnement &#224; stress chronique faible.</p><blockquote><p>&#9888;&#65039; Cette &#233;tude porte sur un seul individu &#8212; aussi exceptionnel soit-il. Elle ne peut pas &#234;tre g&#233;n&#233;ralis&#233;e. Mais elle offre des pistes de biomarqueurs concrets que la science de la long&#233;vit&#233; va maintenant chercher &#224; valider sur des cohortes plus larges.</p></blockquote><p>Ce qui me frappe dans cette &#233;tude, c&#8217;est la convergence avec ce que nous savons d&#233;j&#224; : <strong>l&#8217;inflammation chronique est l&#8217;ennemi num&#233;ro un du vieillissement en bonne sant&#233;</strong>. Le g&#233;nome aide. Le mode de vie construit l&#8217;essentiel.</p><p>Maria Branyas a surv&#233;cu &#224; la grippe espagnole de 1918, &#224; deux guerres mondiales, &#224; la pand&#233;mie COVID &#224; 113 ans. Elle n&#8217;a pas &#8220;bien vieilli&#8221; malgr&#233; ces &#233;preuves &#8212; peut-&#234;tre <em>gr&#226;ce</em> &#224; la r&#233;silience biologique qu&#8217;elles ont contribu&#233; &#224; forger.</p><p>La science de la long&#233;vit&#233; a rarement eu autant de mati&#232;re.

&#233;quipe du Memorial Sloan Kettering Cancer Center de New York a pr&#233;sent&#233; des donn&#233;es de suivi &#224; long terme qui m&#233;ritent toute notre attention.</p><p>Le contexte d&#8217;abord : le cancer du pancr&#233;as est l&#8217;un des cancers les plus redoutables. Son taux de survie &#224; 5 ans tourne autour de 13 %. Il est souvent diagnostiqu&#233; trop tard, et les options th&#233;rapeutiques restent limit&#233;es. Dans la majorit&#233; des cas, seule la chirurgie est curative &#8212; et encore, uniquement lorsque la tumeur n&#8217;a pas encore m&#233;tastas&#233;, ce qui ne repr&#233;sente que 15 &#224; 20 % des diagnostics.</p><p>L&#8217;essai clinique de Phase I, dirig&#233; par le Dr Vinod Balachandran, a inclus 16 patients atteints d&#8217;un cancer du pancr&#233;as op&#233;rable. Chaque patient a re&#231;u un vaccin ARNm <em>enti&#232;rement personnalis&#233;</em>, fabriqu&#233; &#224; partir des n&#233;o-antig&#232;nes extraits de sa propre tumeur &#8212; des mutations sp&#233;cifiques que le syst&#232;me immunitaire apprend ensuite &#224; reconna&#238;tre et attaquer. Le traitement &#233;tait combin&#233; &#224; une immunoth&#233;rapie (pembrolizumab) et une chimioth&#233;rapie standard.</p><div class="pullquote"><p><em>Parmi les 8 patients dont le syst&#232;me immunitaire a r&#233;pondu au vaccin, 7 sont encore en vie six ans apr&#232;s leur derni&#232;re injection. Le taux de survie standard &#224; 5 ans pour ce cancer est de 13 %.</em></p></div><p>L&#8217;histoire de Donna Gustafson, premi&#232;re participante &#224; l&#8217;essai en 2019, illustre parfaitement ces chiffres. Diagnostiqu&#233;e &#224; 66 ans lors d&#8217;un voyage en Australie (ict&#232;re brutal, retour d&#8217;urgence aux &#201;tats-Unis), elle a subi une r&#233;section chirurgicale puis particip&#233; &#224; cet essai. Aujourd&#8217;hui, &#224; 72 ans, elle voyage, c&#233;l&#232;bre ses 50 ans de mariage en Sicile, et dit n&#8217;avoir <em>aucune restriction</em> sur ce qu&#8217;elle peut faire.</p><p>Le vaccin utilis&#233; est le <strong>c&#233;vum&#233;ran autog&#232;ne</strong>, d&#233;velopp&#233; en collaboration avec BioNTech (oui, le m&#234;me laboratoire que les vaccins anti-Covid). Sur la base des r&#233;sultats de la Phase I, un essai mondial de Phase II est d&#233;sormais en cours, parrain&#233; par Genentech, dans plusieurs centres &#224; travers le monde.</p><div class="callout-block" data-callout="true"><p>Ce qui est remarquable ici, c&#8217;est le m&#233;canisme : on ne traite pas le cancer avec une mol&#233;cule g&#233;n&#233;rique. On apprend au syst&#232;me immunitaire du patient &#224; reconna&#238;tre <em>ses propres</em> cellules tumorales, comme une empreinte digitale biologique. C&#8217;est de la m&#233;decine de pr&#233;cision &#224; son degr&#233; le plus avanc&#233;.</p></div><p>Pour les non-r&#233;pondeurs (dont le syst&#232;me immunitaire n&#8217;a pas activ&#233; le vaccin), les r&#233;sultats sont bien moins favorables &#8212; 2 sur 8 encore en vie. Ce qui soul&#232;ve des questions fondamentales sur les facteurs pr&#233;dictifs de la r&#233;ponse immunitaire, et sur comment optimiser le terrain immunologique <em>avant</em> de recevoir ce type de traitement. C&#8217;est pr&#233;cis&#233;ment l&#224; que le biohacking pr&#233;ventif prend tout son sens.</p><p>Nous en sommes encore en Phase II. Mais apr&#232;s des d&#233;cennies d'absence de perc&#233;es r&#233;elles dans ce cancer, ces donn&#233;es sont ce que la recherche oncologique attendait.</p><p class="button-wrapper"

EXP&#201;RIENCE N=1</strong></p><h2><strong>Mon je&#251;ne de 72 heures : discipline, hypoglyc&#233;mie et r&#233;alit&#233; du corps</strong></h2><p>Je suis quelqu&#8217;un qui a toujours faim, et qui aime profond&#233;ment manger. Ce je&#251;ne n&#8217;avait pas pour objectif la perte de poids ni la clart&#233; mentale. Il avait une raison pr&#233;cise : <strong>tenter d&#8217;am&#233;liorer un SIBO qui me suit depuis l&#8217;enfance</strong>, apr&#232;s avoir &#233;puis&#233; antibiotiques, plantes (berb&#233;rine, gingembre, Iberogast), suppl&#233;ments et protocoles avanc&#233;s, sans r&#233;sultat durable.</p><p><strong>0 &#8594; 18H</strong></p><p>Phase simple. Corps en mode de transition, aucune difficult&#233; notable.</p><p><strong>18 &#8594; 24H</strong></p><p>Difficult&#233;s r&#233;elles : insomnie, r&#233;veil nocturne avec faim, sensation de froid, glyc&#233;mie descendue autour de <strong>60 mg/dL</strong>. Rien d&#8217;inqui&#233;tant cliniquement &#8212; mais une r&#233;alit&#233; physique tr&#232;s concr&#232;te.</p><p><strong>24 &#8594; 26H</strong></p><p>J&#8217;ai faim. Je comprends que pour certaines personnes cela soient plus facile mais franchement, je vois des poulets de partout !</p><p><strong>26H &#8594; 36H </strong></p><p>Sommeil tres difficile a venir car j&#8217;avais faim malgr&#233; la m&#233;ditation ce fut rude.<br>R&#233;veil &#224; 2h du matin affam&#233;e. C&#8217;est normal car je souffre d&#8217;hypoglyc&#233;mie nocturne que je r&#232;gle &#224; coup de chrome le soir mais je n&#8217;ai pris aucun suppl&#233;ment. </p><p><strong>36H &#8594; 48H</strong></p><p>Plusieurs alerts de glyc&#233;mie tr&#232;s faible, jusqu&#8217;&#224; 50.</p><p>Mes amis m&#233;decins me disaient que c&#8217;&#233;tait impossible de continuer d&#8217;autant que je pars en long voyage transatlantique avec les tentations et le stress sur le corps.</p><p>Je suis un peu l&#233;thargique et surtout j&#8217;ai super froid. Vraiment froid. J&#8217;ai mis le chauffage.</p><p>J&#8217;esp&#232;re vraiment que cette torture va avoir des r&#233;sultats.</p><p>Je n&#8217;ai plus de bandelettes pour mesurer mon cortisol mais il doit &#234;tre au plafond en mode explosion. Je les re&#231;ois dans quelques heures pour continuer mes analyses.</p><p>Analyses d&#8217;urine : pas mal de ketones dans les urines (logique).</p><p><strong>48H &#8594; 60H</strong></p><p>En avion, j&#8217;ai dormi&#8230;qui dort d&#238;ne :)</p><p>R&#233;veil avec odeurs de viennoiseries et autres gourmandises&#8230;.<br>R&#233;siste, prouve que tu existes !</p><p><strong>60H &#8594; 72H&#8230;..80H</strong></p><p>Course dans les a&#233;roports pour ne pas rater la correspondance et arriv&#233;e &#224; minuit &#224; Paris&#8230;.je mangerai demain matin&#8230;du coup, le je&#251;ne a dur&#233; plus longtemps que pr&#233;vu.</p><p><strong>BILAN</strong></p><p>Pas de r&#233;ponse imm&#233;diate. Je n&#8217;ai pas eu la soit-disant super claret&#233; d&#8217;esprit dont on m&#8217;avait parl&#233;. </p><p>&#199;a a m&#234;me &#233;t&#233; pire : j&#8217;ai fait des erreurs de folie comme oublier tous mes appareils &#233;lectroniques alors que je partais pour un voyage de 3 mois, donner la mauvaise adresse au Uber, etc&#8230;<br><br>Enfin&#8230;je mens&#8230;.car&#8230;..si, une r&#233;ponse imm&#233;diate : PRESQUE PLUS DE SYMPTOMES.<br>Mais un rappel fondamental : le corps ne r&#233;pond pas toujours comme on l&#8217;attend, et les solutions simples sont rarement suffisantes.</p><p>Je pense refaire des 36h, car cela m&#8217;a paru moins impactant c&#244;t&#233; cortisol. Il faut savoir &#233;couter son corps, et se pousser certes, mais ne pas aller dans un inconfort tel que le cortisol explose. Mes bandelettes de cortisol ont &#233;t&#233; sans appel, le je&#251;ne de longue dur&#233;e n&#8217;est pas pour moi.</p><p>Et pour celles et ceux qui me disent &#8220;oui, mais il faut le faire dans un cadre calme, loin de tout, etc&#8230;&#8221; &#8230;vraiment, &#231;a n&#8217;est pas mon truc :) - je n&#8217;ai pas beaucoup de moments o&#249; je suis d&#233;connect&#233;e et quand je les ai, c&#8217;est plus pour aller faire de la plong&#233;e &#224; Bora Bora que dans une ferme perdue &#224; ne pas manger lol.<br>Sinon, heureusement que j&#8217;ai choisi de fare ce long je&#251;ne en plein voyage, cela m&#8217;a occup&#233; l&#8217;esprit.
