Scientists begin first trial to reverse human aging
Yahoo • • health
Key Points:
- Scientists have initiated a clinical trial testing partial cellular reprogramming to treat glaucoma by making older eye cells behave like younger ones, aiming to regenerate damaged optic nerve neurons.
- The trial, led by Life Biosciences, has treated its first participant and plans to enroll up to 12 patients, with potential expansion to related eye conditions.
- The therapy activates three specific genes within aging cells to nudge them toward a younger biological state while retaining their function, offering a novel approach to age-related diseases.
- This approach is promising because many tissues, including the optic nerve, typically lose regenerative capacity with age, and animal studies have shown restored youthful function without major complications.
- Despite early optimism, the treatment remains experimental with risks such as potential cancerous cell changes, and human trials are in the early stages of assessing safety and efficacy.
