Despite the remarkable success of chimeric antigen receptor (CAR) T cell therapies in the treatment of hematological malignancies, this strategy remains challenging in solid tumors. One major obstacle is the hostile immunosuppressive tumor microenvironment. New research demonstrates that targeting PARP11 can overcome this immunosuppression and boost CAR T cell efficacy through stabilization of IFNAR1.
