In UCEC, there were significant differences in the estimated proportions of resting CD4 memory T cells, M0 macrophages, regulatory T cells (Tregs), follicular helper T cells, plasma cells, naive B cells, M1 macrophages, resting mast cells, resting dendritic cells, memory B cells, activated dendritic cells, monocytes, activated CD4 memory T cells, and gamma delta T cells between the tumor and normal groups (Figure 4B). Here, CD4 is linked to neoplasm.
