Based on the results after adjusting for tumor purity, we observed that the level of GPI expression was significantly correlated with multiple immune markers, including CD20, CD70, CD25, CD278, CD191, CD195, CD360, CD196, FOXP3, CD73, PD-1, CTLA4, LAG3, CD68, NOS2, CD163, CD206, CD86, CD14, CD57, KIR3DL1, CD7, CD16, CD1C, and CD141 (p < 0.05, Table 2). This evidence concerns the gene THBD and neoplasm.
