IL-10 and TGF-β reduce synthesis of interferon-gamma (IFN-γ) and TNF-α by pro-inflammatory CD4 T cells, thus, lower tumor-specific cytotoxicity of CD8 cells, inhibit the main functions of dendritic cells and NK cells and this way induce tolerance to tumor cells [33,34]. Here, TGFB1 is linked to neoplasm.
