CD274 and neoplasm: To investigate the effect of anti-PD-L1 treatment on inflammatory cyto- and chemokine production after melanoma cancer disease, a multiplex assay was performed to compare the concentration of 23 different inflammatory cytokines and chemokines in LV tissue of anti-PD-L1 and isotype Ctrl treated B16F10-GCV mice after tumor elimination and recovery (50 days after tumor induction and 43 days after starting anti-PD-L1 or isotype Ctrl treatment).
