T cell stemness and dysfunction in tumors are triggered by a common mechanism

Abstract excerpt

Stemness against adversity T lymphocytes are powerful immune cells that can destroy tumors, but cancers have developed tricks to evade killing. Vodnala et al. found that potassium ions in the tumor microenvironment serve a dual role of influencing T cell effector function and stemness (see the Perspective by Baixauli Celda et al. ). Increased potassium impairs T cell metabolism and nutrient uptake, resulting in a...
