Cytokines play crucial roles in regulating the proliferation, differentiation and functions of a variety of cells. In this study, we investigated the biological activities of a novel cytokine named as CX1, which was origically isolated in our lab recently. Sharing homology to interleukin(IL)-17, cytokine CX1 promotes the proliferation of granulopoiesis and erythropoiesis, and stimulates the production of IL-6 and tumor necrosis factor (TNF-a) by monocytes. But it exhibits no obvious effects on dendritic cells or T lymphocytes. By expression cloning, the receptor for cytokine CX1 was identified, which encodes a type I membrane receptor of 502 residues. Furthermore, the Fc fusion protein for the extracellular domain of the receptor was successfully generated and functionally confirmed. Taken together, these data are valuable to better understanding the biological functions of cytokine CX1.
