Furthermore, we assessed immune cell infiltration by quantifying several immune cell types involved in the tumor immune response, including Treg cells (CD4+Foxp3+ T cells), M1 macrophages (CD80+CD11c+ cells), M2 macrophages (CD80+CD206+ cells), PD-1+CD8+ cells, and CD39+CD8+ cells. This evidence concerns the gene FOXP3 and neoplasm.
