Chemokine ligand 10 (CXCL10), also known as γ-interferon inducible protein 10 (IP-10) or microinducible cytokine B10, is a small molecular weight cytokine belonging to the CXC chemokine family. IP-10 is secreted by many types of cells in response to IFN-γ, including monocytes, endothelial cells, and fibroblasts, etc. IP-10 has multiple functions, such as chemotaxis to monocytes/macrophages, T cells, NK cells, and dendritic cells, promotion of T-cell adhesion to endothelial cells, antitumor activity, and inhibition of bone marrow colony formation and angiogenesis.
