Abstract excerpt
Chronic stimulation in the tumor microenvironment can induce exhausted CD8+ T (Tex) cells that have limited tumoricidal activity. Here, we show an inverse correlation between signal strength and Tex cell differentiation by using patient-derived mutations in the T cell receptor (TCR)-signaling protein CARD11. Strong TCR signaling of the E134G mutant inhibits Tex cell differentiation and increases tumor growth....
