Moreover, these results reveal the potential regulating role of CFP in T cell and neutrophils, which including the increase of CFP expression positively correlates with the expression of neutrophils and T cell (general) gene markers (MPO, CD15, CD66B, CD11b, CCR7, CD3D, CD3E, CD2) in STAD and LUAD. Here, CEACAM8 is linked to gastric adenocarcinoma.
