Correlation between T-cell exhaustion markers and M2 macrophage marker. (A) Correlation plot between CD163 and LAG3, between CD163 and FAP, and between CD163 and programmed death-ligand 1 in lymphoma cell areas. (B) Correlation plot between CD163 and LAG3, between CD163 and TIM-3, and between CD163 and PD1 in immune cell areas. (C) The expression of LAG3 and FAP according to patch-, plaque-, and tumor-stage MF in the lymphoma cell area. (D) The expression of LAG3 and TIM-3 according to patch-, plaque-, and tumor-stage MF in the immune cell area.
