Tumor-induced peripheral immunosuppression promotes brain metastasis in patients with non-small cell lung cancer
ConclusionsThe frequency of PD-L1+ myeloid cells correlated with the presence of brain metastases. Tumor-derived IL-6 was capable of inducing PD-L1+ myeloid cells in vitro, suggesting that monitoring of immunosuppressive factors in peripheral blood may identify new targets for therapeutic intervention in selected patients.
