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. The gene discussed is CD8A; the disease is gastric adenocarcinoma.
