The boxplot showed the different immune cells statement of tumor samples, demonstrating that the enrichment of naive B cells (Figure 1D), memory B cells (Figure 1E), CD8+ T Cells (Figure 1F), activated memory CD4+T Cells (Figure 1G), activated NK cells (Figure 1H), M0 macrophages (Figure 1I), M1 macrophages (Figure 1J) and M2 macrophages (Figure 1K) was significantly changed in many cancer types, especially in breast cancer samples. Here, CD8A is linked to breast cancer.
