Immunotherapy responses of patients with metastatic melanoma are linked to IL-17 signaling

Treatment with immune checkpoint inhibitors (ICIs) has improved the survival of patients with metastatic melanoma. However, although ICIs are promising for achieving lasting clinical responses, only a subset of patients receive substantial benefit. Our results suggest that the IL-17 pathway supports the response of melanoma to dual ICI therapy and might represent a biomarker for patient stratification.
