Therapeutically Increasing MHC-I Expression Potentiates Immune Checkpoint Blockade

Abstract
Loss of the NFκB pathway inhibitor TRAF3 increased MHC-I expression, improving T cell–mediated cancer cell killing and tumor responsiveness to immune checkpoint blockade, an effect that could be mimicked with the drug birinapant.
