Slowing down to take it in: Endocytosis during cellular aging

Aging cells functionally decline and accumulate damage through poorly understood mechanisms. In this issue, Antentor et al. (https://doi.org/10.1083/jcb.202412064) find that increased vacuolar pH in older yeast cells slows clathrin-mediated endocytosis. These findings have broad implications in aging-related plasma membrane protein quality control.
