Chemokine C-X-C motif ligand 10 Overview

Chemokine C-X-C motif ligand 10 (CXCL10), also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10, is a small pro-inflammatory chemokine belonging to the CXC chemokine family. It plays a central role in immune cell trafficking and inflammation by binding primarily to the CXCR3 receptor. CXCL10 expression is strongly induced by interferon-gamma (IFN-γ) in various cell types. Elevated levels or dysregulation of CXCL10 have been implicated in numerous diseases, including cancer, viral infections, autoimmune diseases and renal diseases.

Mechanism of Action

CXCL10 exerts its effects mainly through binding to the G-protein coupled receptor CXCR3 on target leukocyte subsets. This triggers downstream signaling cascades leading to calcium influx and cytoskeletal rearrangement required for directed migration ("chemotaxis"). Additional effects include modulation of apoptosis pathways via caspase activation.

Safety Considerations

  • Dysregulation of CXCL10 can contribute to pathological inflammation and tissue damage.
  • In some contexts, CXCL10/CXCR3 signaling can mediate detrimental neuroinflammation and apoptosis.

Associated Biomarkers

Biomarker
CXCL10 levels can be a biomarker for disease activity and treatment response in various inflammatory conditions and infections.
