A CD68-expressing tissue-homing subset in peripheral CD8+ T cells predicts response to anti-PD-1 therapy in lung cancer
BackgroundT-cell function is regulated by immunometabolism, and lysosomes are signaling hubs. CD68 (LAMP4), traditionally regarded as a monocyte/macrophage marker, has been largely neglected in T cell biology. We aimed to assess the link between CD68 e…
