Our data demonstrated that GPX8 was correlated with mRNA expression of immune markers of CD8+ T cells (CD8B), CD4+ T cells (CD4), T cells (CD3D), macrophages (CD68 and ARG1), neutrophils (ITGAM and CCR7), dendritic cells (NRP1), NK cells (B3GAT1), and tumor-associated fibroblasts (FAP). The gene discussed is CD3D; the disease is neoplasm.
