However, HCMV infection has no effect on the protein level of STING in plasmacytoid dendritic cells (pDC), monocyte-derived dendritic cells (moDC) or granulocyte-macrophage colony-stimulating factor (GM-CSF) cultured bone marrow-derived macrophages (GM-CSF-MΦ), whereas it slightly reduces the protein level of STING in monocyte-derived macrophages (moMΦ) (Paijo et al., 2016). Here, CSF2 is linked to cytomegalovirus infection.
