The role of UBR2 in triple-negative breast cancer and its implications for immune checkpoint blockade therapy

Our findings indicate that the inhibition of UBR2 can augment TIL infiltration by diminishing PD-L1 expression, thereby emerging as an efficacious strategy (the functional inhibitors of UBR2) to enhance the therapeutic efficacy of PD-L1/PD1 blockers, offering a novel perspective for the treatment of TNBC through combined immunotherapy.
