We then reassessed the B cell, CD4+ T cell, CD8+ T cell, neutrophil, macrophage, and DC infiltration scores in each tumor for each patient based on gene expression level, and the results were all positively correlated with the ITGA8 expression and revealed more immune infiltration (Figure 2F, B cell, r = 0.33, p < 0.001; CD4+ T cell, r = 0.38, p < 0.001; CD8+ T cell, r = 0.28, p < 0.001; neutrophil, r = 0.22, p < 0.001; macrophage, r = 0.35, p < 0.001; and DC, r = 0.37, p < 0.001). This evidence concerns the gene CD8A and neoplasm.
