MCT4-mediated lactate efflux promotes STING-dependent dendritic cell antitumor immunity.

Blocking a tumor cell molecule that suppresses immune responses could enhance immunotherapy effectiveness by activating immune cells more powerfully.

MCT4-mediated lactate efflux from tumor cells activates the STING pathway in dendritic cells, creating a novel metabolic-immune coupling mechanism that promotes antitumor DC immunity; targeting MCT4 represents a new approach to enhancing immunotherapy efficacy. This record was retained from the prior triage attempt for PubMed pipeline handoff.
