‘Proteotoxic Shock’: Ohio State Researchers Uncover Hidden Mechanism Behind Immunotherapy Failure
A landmark study by Ohio State scientists reveals the underlying mechanism of cancer immunotherapy failure: a fatal “proteotoxic shock” or protein quality control collapse (TexPSR) in T-cells. This newly identified stress pathway overwhelms immune cells with misfolded proteins, disabling their tumor-fighting function. Crucially, blocking the TexPSR pathway in preclinical models restored T-cell function and made immunotherapy markedly more effective, offering an entirely new target for cancer treatment development.
