Figure 7. The correlation analysis between the expression level of SLC1A5 and the infiltration level of immune cells. The expression level of SLC1A5 was positively correlated to the infiltration level of (A, B) CD4+T cells. The expression of SLC1A5 was negatively correlated with the number of (C) CD8+T cells, (D) B cells, (E) neutrophils and (F) macrophages.
