The correlation between SLC7A7 expression and the level of immune cell infiltration was assessed with an immune infiltration assay, tumor tissues with higher SLC7A7 expression levels were accompanied by higher Infiltration Score, CD8_T cells, Central memory cells, Cytotoxic cells, DC cells, Exhausted cells, iTreg cells, Macrophage cells, Monocyte cells, NK cells, Tfh cells, Th1 cells, Th2 cells, Tr1 cells. The gene discussed is SLC7A7; the disease is neoplasm.
