In lung adenocarcinoma (LUAD), there was a correlation between the expression of CENPFand B cells and neutrophils infiltration, AURKA and B cells, CD4+ T cells, macrophages, and dendritic cells infiltration, PBK and B cells, CD4+ T cells, macrophages, and dendritic cells infiltration, and CCNB1 and B cells, CD4+ T cells, macrophages, and dendritic cells infiltration (p < 0.05) (Figure 7). Here, CD4 is linked to lung adenocarcinoma.
