Osaka researchers find AP2A1 protein that slows cellular aging

Researchers at Osaka University identified the AP2A1 protein as central to cellular senescence. Blocking it made old cells divide again and shrink, and combining it with the compound IU1 reduced aging markers. The study, published in Cellular Signalling, was done only in cell cultures.

• AP2A1 keeps senescent cells large and immobile
• Blocking AP2A1 restored division and smaller size in old cells
• Combining with IU1 boosted cleanup of damaged proteins and cut aging markers
• Experiments were in vitro, far from a human therapy
