Studies have reported that chemerin/CMKLR1 promotes chemotactic responses of many immune cells and non-immune cells, including macrophages, immature myeloid and plasmacytoid DCs, NK cells, vascular smooth muscle cells (SMCs), endothelial cells, and gastric cancer cells [13,34,35,36,37,38,39,40]. This evidence concerns the gene CMKLR1 and gastric cancer.
