CD8A and intrahepatic cholangiocarcinoma: For example, ICC samples with high CD73 expression showed higher infiltration scores of central memory CD8 T cell, effector memory CD8 T cell, regulatory T cell, myeloid-derived suppressor cell, macrophage, and neutrophil, which was not consistent with the CIBERSORT results estimating a reduced CD8 + T cell infiltration in CD73 high group.
