CD4 and gastric adenocarcinoma: The results of our analysis showed that, the CFP expression in LUAD and STAD was positively correlated with the number of CD8+ T cells, CD4+ T cells, macrophages, neutrophils and dendritic cells and negatively correlated with immune infiltration (Figure 5), suggesting that the CFP may be involved in the immunomodulatory mechanisms of LUAD and STAD.
