Abstract
The presence of CD8+ T cells coexpressing residency and exhaustion molecules in chronic diseases often correlate with clinical outcomes; however, the relationship between these cells and conventional tissue-resident memory (TRM) cells or exhausted CD8+ T (TEX) cells is unclear. Here we show that chronic antigen stimulation drives development of tissue-resident TEX (TR-TEX) cells that are distinct from TRM cells generated after antigen clearance. TR-TEX and TRM cells are regulated by different transcriptional networks with only TR-TEX cells being Tox-dependent for residency programming. While TEX cells (including TR-TEX) are unable to generate TRM cells after antigen withdrawal, TRM cells differentiate into TEX cells upon chronic antigen exposure. Cell-state-specific transcriptional signatures reveal a selective association of TR-TEX cells with patient responses to immune checkpoint blockade, and only TR-TEX but not TRM cells responded to PD-1 pathway inhibition in vivo. These data suggest that TR-TEX and TRM cells are developmentally divergent cell states that share a tissue-residency program but have distinct roles in disease control.
