C-X-C motif chemokine 10 (CXCL10) also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10 is an 8.7 kDa protein that in humans is encoded by the CXCL10 gene. The gene is located on human chromosome 4 in a cluster among several other CXC chemokines. CXCL 10 is a small cytokine belonging to the CXC chemokine family. It is secreted by several cell types in response to IFN-γ. CXCL10 has been attributed to several roles, such as chemoattraction for 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.
