B, Downregulation of CD69 expression (% and MFI) on CD8+ T-cells after co-incubation with PD-L1high exosomes. In C, blocking of exosome-mediated down-regulation of CD69 expression on CD8+ T cells by anti-PD-1 Ab. Note that inhibition mediated by PD-L1high exosomes was almost completely reversed (% and MFI) by adding the PD-1 inhibitor. * p< 0.05; ** p<0.005

Article Snippet: Next, anti-PD-1 Ab, #AF1086 lot #ICA02 (purchased from R&D Systems) was used to block effects of exosome-mediated suppression.
