The Kynurenine Pathway as a possible resistance mechanism to immunotherapy in sarcomas

Background Sarcomas are heterogeneous malignant mesenchymal tumors known to be particularly resistant to immunotherapy. This resistance highlights the need to better understand the biological mechanisms limiting response to immune checkpoint inhibitors. We previously observed increased activity of the kynurenine pathway in the plasma of patients treated with pembrolizumab and metronomic cyclophosphamide. The kynurenine pathway is […]
