Distinct Populations of Immune-Suppressive Macrophages Differentiate from Monocytic Myeloid-Derived Suppressor Cells in Cancer

Here, we report that functional heterogeneity of macrophages in cancer could be determined by the nature of their precursors: monocytes (Mons) and monocytic myeloid-derived suppressor cells (M-MDSCs). Macrophages that are differentiated from M-MDSCs, but not from Mons, are immune suppressive, with a...

Shrnutí:Here, we report that functional heterogeneity of macrophages in cancer could be determined by the nature of their precursors: monocytes (Mons) and monocytic myeloid-derived suppressor cells (M-MDSCs). Macrophages that are differentiated from M-MDSCs, but not from Mons, are immune suppressive, with a genomic profile matching that of M-MDSCs. Immune-suppressive activity of M-MDSC-derived macrophages is dependent on the persistent expression of S100A9 protein in these cells. S100A9 also promotes M2 polarization of macrophages. Tissue-resident- and Mon-derived macrophages lack expression of this protein. S100A9-dependent immune-suppressive activity of macrophages involves transcription factor C/EBPβ. The presence of S100A9-positive macrophages in tumor tissues is associated with shorter survival in patients with head and neck cancer and poor response to PD-1 antibody treatment in patients with metastatic melanoma. Thus, this study reveals the pathway of the development of immune-suppressive macrophages and suggests an approach to their selective targeting. [Display omitted] •M-MDSCs, in contrast to monocytes, differentiate into immune-suppressive macrophages•M-MDSC-derived macrophages fail to downregulate expression of S100A8/A9 proteins•High expression of S100A9 regulates suppressive activity of macrophages via C/EBPβ•S100A9+ macrophages are associated with negative clinical outcome in cancer patients Kwak et al. report that tumor immune-suppressive macrophages differentiate from the population of myeloid-derived suppressor cells (MDSCs). This effect is dependent on the persistent expression of S100A9 protein. The presence of S100A9-positive macrophages in tumors is associated with shorter survival and poor response to immunotherapy of cancer patients.
