CD4 and breast cancer: Moreover, natural regulatory T cells (nTreg), CD4 naïve T cells (CD4_naive), type 1 regulatory T cells (Tr1), and monocytes were negatively correlated, whereas natural killer T cells (NKT) , macrophages, effector memory cells, T helper type 2 (TH2), B cells, dendritic cells (DCs), and gamma delta T cells (gamma delta) positively correlated with the gene expressions of DEPs, exhibiting their extensive impact on immune infiltrations in breast cancer patients.
