Chemical anchoring of immunotherapeutic drugs within senescent tumor cells overcomes senescence-driven immunotherapy resistance.
A novel chemical strategy keeps immunotherapy drugs working inside cancer cells longer, potentially overcoming a major source of treatment failure.
Researchers developed a novel SA-β-gal-activated bio-orthogonal chemical anchoring strategy that selectively traps combined IDO inhibitor and PD-L1 blocking peptide within senescent tumor cells, bypassing drug efflux pumps and reversing immunotherapy resistance. The approach showed efficacy in female mouse models and represents a highly novel mechanistic strategy to overcome a major barrier in cancer treatment.
