STING1 and neoplasm: For example, DNA carried by exosomes or exosome‐like EVs originating from tumour cells responding to chemotherapy (though not dying by effector caspase‐dependent apoptosis) is sensed by the cGAS‐STING (Stimulator of INterferon Genes) pathway in recipient dendritic cells that are consequently activated to promote anti‐tumour T cell‐mediated immunity [122].
