Abstract |
Recent findings have shown the significance of CD163-positive macrophages in tumor progression, yet there have been few studies on the function of CD163 in macrophages. Here, we uncover the role of CD163 in macrophage activation using CD163-deficient mice and human samples. We detected CD163 in 62 undifferentiated pleomorphic sarcoma samples, in which a high percentage of CD163-positive macrophages was associated with decreased overall survival and higher histologic grade. We observed macrophage-induced tumor cell proliferation in cocultures of human monocyte-derived macrophages and leiomyosarcoma (TYLMS-1) and myxofibrosarcoma (NMFH-1) cell lines, which was abrogated by silencing of CD163. Tumor development of sarcoma (MCA205 and LM8) cells in CD163-deficient mice was significantly abrogated in comparison with wild-type (WT) mice. Coculture with WT peritoneal macrophages significantly increased proliferation of MCA205 cells but decreased in the presence of CD163-deficient macrophages. Production of IL6 and CXCL2 in CD163-deficient macrophages was suppressed in comparison with WT macrophages, and overexpression of CD163 in CD163-deficient macrophages induced production of IL6 and CXCL2. Silencing of IL6 but not CXCL2 abrogated macrophage-induced proliferation of MCA205 cells. Taken together, our results show that CD163 is involved in protumoral activation of macrophages and subsequent development and progression of tumors in mice and humans.Significance: Macrophage CD163-mediated induction of IL6 promotes tumor development and progression in murine and human malignant tumors.
