CD4 and neoplasm: Therefore, we explored the correlation between the expression of CDCA3 and gene markers of different immune cells, such as B cells, neutrophils, monocytes, tumor-associated macrophages (TAMs), M1 and M2 macrophages, CD4+ T cells, CD8+ T cells, natural killer cells (NK cells), dendritic cells, and different T cells, including Tregs, T-helper 1 cells (Th1), T-helper 2 cells (Th2), T-helper 17 cells (Th17), follicular helper T cells (Tfh), and exhausted T cells.
