STAT1 and prostate adenocarcinoma: Further studies on immune cell type marker PRAD (Table 1) showed that the expression level of TMPRSS2 mRNA was correlated with B-cells (CD19, CD27, and CD38), and CD8+ in PRAD T-cells (CD8A and CD8B), neutrophil granulocytes (FCGR3B, SIGLEC5, and S100A12), macrophages (CD84 and CD163), Th1 (STAT4 and STAT1), Treg (STAT5B and TGFB1), and T-cell failure (PDCD1, CTLA4, LAG3, and GZMB) were significantly correlated, suggesting that these results strongly confirm the close correlation between TMPRSS2 and immune infiltration of PRAD.
