Aging in human natural killer (NK) cells is linked to lipid accumulation, softer cortical mechanics, disorganized immune synapses, and impaired target killing.
- Why it matters: Immune surveillance declines with age, but the lipid–biomechanics mechanisms that physically constrain NK cell function are not well defined.
- What they did: The study mapped age-associated metabolic and mechanical changes in NK cells and tested a retinoid–SREBP1–ELOVL6 pathway, using ELOVL6 inhibition to probe causality.
- The result: Blocking ELOVL6 restored membrane and cortical mechanics, rescued cytotoxicity in vitro, and enhanced antitumor activity in mouse models, supporting a targetable aging-linked mechanism.
