CD8 T cells following coculture with PD-1+ monocytes presented lower IFN-γ and lower TNF-α expression, together with lower proliferation capacity, than CD8 T cells following coculture with PD-1- monocytes, suggesting that PD-1+ monocytes were less capable of supporting CD8 T cell activation. Overall, these data indicated that PD-1 expression was elevated in monocytes from hepatocellular carcinoma patients. In addition, PD-1+ monocytes presented a preference toward M2 polarization and had a deficiency in supporting CD8 T cells.
