cGAS-STING–mediated DNA sensing maintains CD8 + T cell stemness and promotes antitumor T cell therapy

T cells from patients with cancer and potentiated antitumor responses of CAR-T cell therapy in a xenograft model. These findings advance our understanding of inherent cGAS-STING activation in T cells and provide insight into the development of improved T cell therapy by harnessing the cGAS-STING pathway for cancer immunotherapy.
