However, a comparison between anti-PD-1-treated B16F10E and anti-PD-1-treated B16F10E-KO for the expression of MHC-I and PD-L1 did not reveal significant differences suggesting that the observed CTL-mediated activities in αV-KO tumours were not associated with optimized antigen presentation by target cells nor with decreased PD-L1 expression. Here, CD274 is linked to neoplasm.
