Delivery of CAR T Cells in a Magnesium-Functionated Hydrogel Boosts Peritoneal Metastasis Treatment.
Chimeric antigen receptor (CAR) T cells show limited efficacy in solid tumors due to suppressive factors in the tumor microenvironment. In this study, we identified extracellular magnesium (Mg2+) as a pharmacologically modulable regulator of CAR T activity. Mg2+ supplementation increased early activation and augmented...
