Dr. Noah Davidsohn, co-founder and CSO of Rejuvenate Bio, discusses the company's innovative work using gene therapies to treat age-related diseases in dogs and humans. In his conversation with host Chris Patil, he explains his recent groundbreaking study showing that partial cellular reprogramming with Yamanaka factors extended lifespan and healthspan in very old mice. Noah then outlines Rejuvenate's clinical pipeline, including targeting longevity pathways like FGF-21 for heart disease and combining TGF-beta inhibition with klotho for osteoarthritis. By choosing secreted factors deliverable with liver-targeted gene therapy, Rejuvenate hopes to circumvent delivery challenges. Noah conveys an inspiring vision of adding healthy years to dogs' and humans' lives.
