CD4 and carcinoma: The results showed that the CD209 expression was evidently correlated with the infiltration of CD8+ T cells (Figure 5A), CD4+ T cells (Figure 5B), Treg cells (Figure 5C), B cells (Figure 5D), monocytes (Figure 5E), NK cells (Figure 5F), myeloid dendritic cells (Figure 5G), neutrophils (Figure 5H), macrophages (Figure 5I), and cancer-associated fibroblasts (Figure 5J) in pan-carcinoma patients.
