On the other side, macrophages (cor = 0.629), dendritic cells (cor = 0.542), CD4+T cells (cor = 0.539), Neutrophils (cor = 0.465), B cells (cor = 0.441), and CD8+T cells (cor = 0.415) all had the highest correlation with ENO2, indicating that this gene, among seven HR-DEmRNA-os in the ceRNA network, might play the most important role in tumor immune infiltration. This evidence concerns the gene CD4 and neoplasm.
