| مستخلص: |
Despite their potent antitumor activity, clinical application of immune checkpoint inhibitors has been significantly limited by their poor response rates (<30%) in cancer patients, primarily due to immunosuppressive tumor microenvironments. As a representative immune escape mechanism, cancer‐derived exosomes have recently been demonstrated to exhaust CD8+ cytotoxic T cells. Here, it is reported that sulfisoxazole, a sulfonamide antibacterial, significantly decreases the exosomal PD‐L1 level in blood when orally administered to the tumor‐bearing mice. Consequently, sulfisoxazole effectively reinvigorates exhausted T cells, thereby eliciting robust antitumor effects in combination with anti‐PD‐1 antibody. Overall, sulfisoxazole regulates immunosuppression through the inhibition of exosomal PD‐L1, implying its potential to improve the response rate of anti‐PD‐1 antibodies. [ABSTRACT FROM AUTHOR] |
