A University College London team demonstrates that modulating necroptosis, a regulated necrosis pathway, enhances cellular resilience by pausing harmful death signals and enabling repair. Their preclinical mouse studies reveal improved cognitive function and extended lifespan, indicating therapeutic potential against age-related degeneration.
Key points
- Pharmacological inhibition of the RIPK3-MLKL axis to delay regulated necrosis in aged murine models.
- Reduced DAMP release lowers neuroinflammation and improves cognitive performance.
- Extended median lifespan observed without disrupting essential apoptotic functions.
Why it matters: Modulating necroptosis shifts anti-aging paradigms by targeting regulated cell death pathways, offering precise intervention over broad-spectrum senolytic approaches.
