MDSC and macrophages are present in most solid tumors and are important drivers
of immune suppression and inflammation. It is established that cross-talk between
MDSC and macrophages impacts anti-tumor immunity; however, interactions between
tumor cells and MDSC or macrophages are less well studied. To examine potential
interactions between these cells, we studied the impact of MDSC, macrophages, and
four murine tumor cell lines on each other, both in vitro and in vivo. We focused
on IL-6, IL-10, IL-12, TNF-?, and NO, as these molecules are produced by
macrophages, MDSC, and many tumor cells; are present in most solid tumors; and
regulate inflammation. In vitro studies demonstrated that MDSC-produced IL-10
decreased macrophage IL-6 and TNF-? and increased NO. IL-6 indirectly regulated
MDSC IL-10. Tumor cells increased MDSC IL-6 and vice versa. Tumor cells also
increased macrophage IL-6 and NO and decreased macrophage TNF-?. Tumor
cell-driven macrophage IL-6 was reduced by MDSC, and tumor cells and MDSC
enhanced macrophage NO. In vivo analysis of solid tumors identified IL-6 and
IL-10 as the dominant cytokines and demonstrated that these molecules were
produced predominantly by stromal cells. These results suggest that inflammation
within solid tumors is regulated by the ratio of tumor cells to MDSC and
macrophages and that interactions of these cells have the potential to alter
significantly the inflammatory milieu within the tumor microenvironment.
