What the research found
Nature Aging published a research article online on 11 November 2026. Xinru Liu, Fang Ni, and colleagues describe a retinol, SREBP1, and ELOVL6 lipogenic axis that remodels natural killer cell biomechanics and constrains immune surveillance during aging. The public abstract excerpt says aging drives a lipid-biomechanical change in human natural killer cells that contributes to age-related immune decline. That excerpt ends before any sample size, age band, sex split, or p value, so none of those are stated here. This is a cell study of aging. DOI 10.1038/s43587-026-01262-4. Not medical advice.
