CBX5 mRNA was correlated with CD4+ T cells (ρ = 0.252, p = 4.02−8), macrophages (ρ = 0.387, p = 6.47−18), neutrophils (ρ = 0.364, p = 6.57−16) and dendritic cells (ρ = 0.220, p = 1.91−6) in ccRCC, while it was associated only with dendritic cells (ρ = 0.162, p = 9.13−3) in pRCC patients. Here, CD4 is linked to nonpapillary renal cell carcinoma.
