CD4 and neoplasm: We comprehensively evaluated the immune cell profiles within the tumor microenvironment by determining the proportions of dendritic cells (CD86HiCD11c+ DCs and CD80HiCD11c+ DCs), T cells (CD4+ T cells and CD8+ T cells), effector/memory T cells (CD44+CD62L−CD8+ TEM cells), cytotoxic T cells (IFNγ+CD8+ T cells and TNFα+CD8+ T cells) and regulatory T cells (CD127+CD25+CD4+ Treg cells).
