CD274 and hepatocellular carcinoma: Striking differences between responders and non-responders were detected for GranB expressions in CD8+ T cells only in close-I (FDR-adjusted p = 0.00123) and in PD-L1 expressions in HCC/hepatocytes in close-I and far-I regions (FDR-adjusted p < 10-4), but not for other regions.
