Description

General description

The gene for C-X-C motif chemokine ligand 10 (CXCL10), also known as interferon-γ-inducible protein-10 (IP-10), is mapped to human chromosome 4q21.1.[1] IP-10 is secreted by monocytes, neutrophils, endothelial cells, keratinocytes, fibroblasts, mesenchymal cells, dendritic cells, astrocytes and hepatocytes.[2] It is a polypeptide of 78 amino acids. Human IP-10 shows 67% amino acid homology to mouse CRG-2.

Biochem/physiol Actions

IP-10 (interferon-γ-inducible protein-10) protein is a proinflammatory chemokine which controls immune responses. It interacts with chemokine receptor 3 (CXCR3) and activates leukocytes including T cells, eosinophils, monocytes and natural killer cells. Mutations in IP-10 are associated with rheumatoid arthritis.[3] In humans with chronic hepatitis C virus (HCV) infection or HCV/human immunodeficiency virus (HIV) co-infection, IP-10 is linked with obesity and insulin resistance.[2]

IP-10, a chemoattractant for activated T lymphocytes, is a potent inhibitor of angiogenesis and displays thymus-dependent anti-tumor effects.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline with 5% trehalose containing 50 μg bovine serum albumin per 1 μg of cytokine.

Analysis Note

The biological activity is measured by its ability to chemoattract mouse BaF/3 cells transfected with hCXCR3.
