After comprehensively inspecting the association between tumor immune infiltration of 23 common immune cells and the expression of SLC25A5 and SLC25A24 (Fig. S3D), we revealed that the expression of SLC25A5 was negatively related to the infiltration of CD8+ T cells (r = −0.23, p < 0.001) and positively related to neutrophils (r = 0.10, p < 0.05), while the expression of SLC25A24 was positively related to the infiltration of CD8+ T cells (r = 0.21, p < 0.001), neutrophils (r = 0.11, p < 0.05), B cells (r = 0.13, p < 0.01), and macrophages (r = 0.18, p < 0.001) (Fig. 5G). The gene discussed is CD8A; the disease is neoplasm.
