In lung squamous carcinoma (LUSC), there was a correlation between the expression of CENPF and tumor purity, B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells infiltration, AURKA and tumor purity, B cells, CD4+ T cells, macrophages, and dendritic cells infiltration, PBK and tumor purity, CD4+ T cells, macrophages, neutrophils, and dendritic cells infiltration, and CCNB1 and tumor purity, B cells, CD4+ T cells, macrophages, and dendritic cell infiltration (p < 0.05) (Figure 7). Here, CD4 is linked to neoplasm.
