<b>Purpose:</b> The microenvironment of head and neck squamous cell carcinomas (HNSCC) is highly immunosuppressive. HNSCCs expressing elevated levels of PD-L1 have especially poor outcome. Exosomes that carry PD-L1 and suppress T-cell functions have been isolated from plasma of patients with HNSCC. The potential contributions of PD-L1<sup>+</sup> exosomes to immune suppression and disease activity are evaluated.<b>Experimental Design:</b> Exosomes isolated from plasma of 40 HNSCC patients by siz ...[more]
