OT-55 reshapes tolerogenic BH3-mimetic-induced apoptosis toward immunogenic cell death in AML, potentiating PD-1/Tim-3 blockade.
A drug combination flips cancer cells' death mechanism from suppressing to activating immunity, enhancing immunotherapy in leukemia.
This Cell Death & Disease study demonstrates that OT-55 shifts the apoptotic program from venetoclax-type BH3-mimetics from immunosuppressive to immunogenic in AML cells, enabling synergistic anti-tumor immunity with dual PD-1/Tim-3 blockade. The finding provides a mechanistic rationale for combining BH3-mimetics with immune adjuvants to enhance immunotherapy efficacy in AML.
