KLRG1 and renal cell carcinoma: To determine whether TIGIT+KLRG1+ memory CD8+ T cells are similar across disease settings, we compared EOMES module expression in sorted TIGIT+KLRG1+ memory CD8+ T cells and TIGIT-KLRG1- memory CD8+ T cells from HC, individuals with T1D, and individuals with RCC; RCC was included because cancer is a setting where exhaustion is expected (1).
