Restoring cellular recycling clears 'zombie' cells

A decline in chaperone‑mediated autophagy (CMA) makes aged senescent cells accumulate and evade immune removal; boosting CMA (for example with CA77.1 in mice) reduces senescent‑cell buildup, inflammation, and disease severity in preclinical models. This suggests anti‑aging approaches could focus on restoring cell‑recycling mechanisms rather than killing senescent cells outright. — If validated in humans, shifting from senolytic killing to restoring immune‑mediated clearance via CMA could change drug development priorities, clinical trial design, and regulatory oversight for aging therapies.
