Senescent cells exist in a spectrum of 'exit-competent' versus 'exit-incompetent' states determined by p21/p16 ratio and NAD+ availability. Therapeutic intervention targeting SIRT1 activation combined with CDK4/6 modulation could selectively rescue exit-competent cells while eliminating terminally senescent ones.
Debate provenance: derived from debate `sess_SDA-2026-04-08-gap-debate-20260406-062101-7751c220` on question: The highest-ranked hypothesis assumes senescence reversibility through metabolic reprogramming, but the debate did not establish whether senescent cells can return to normal function or only halt further deterioration. This mechanistic distinction is fundamental to therapeutic expectations.
