CD8A and cancer: Further analysis of immune cell infiltration revealed that PLAG1 is positively correlated with the infiltration levels of B cells, T cells, and dendritic cells (DC) in cancer types such as LGG, GBMLGG, PRAD, and BRCA, while it is negatively correlated with the infiltration of certain immune cells (such as CD8+ T cells and dendritic cells) in cancer types including KIRC and LIHC (Figure 7B).
