The immune infiltration analysis of CCR5, FCER1G, and ITGB2 revealed significantly positive correlations between their expression and the infiltration levels of B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells, implicating the role of these three genes in regulating tumor immunology in EC. Here, ITGB2 is linked to neoplasm.
