Desc: À la recherche de la jeunesse perdue: Directed by Sylvie Gilman, Thierry de Lestrade. With Olivier David, Sylvie Gilman, Laurent Lederer. Today, ageing is no longer considered by researchers as an irreversible phenomenon but as a disease that could be cured. To achieve this, scientists are exploring different avenues with the aim of reducing the biological age which, unlike the chronological age, reflects the physiological or functional state of the individual. The administration of a popular anti-diabetic drug to prevent age-related pathologies, the destruction of ageing cells using a senolytic treatment, the transfusion of blood from a younger person to an older one, gene therapy using cell rejuvenation: these are all innovations that are attracting a growing number of Silicon Valley billionaires, always on the lookout for promising investments.
