CXCL10 (IP-10): Navigating the Complex Landscape of Inflammatory Signaling

CXCL10 or Interferon gamma inducible Protein 10 (IP-10) is becoming increasingly recognized as a chemokine, in the realm of immune system communication and inflammatory reactions. The compact but potent protein acts as a messenger at the level to coordinate cell interactions essential, for our body’s defence mechanisms and inflammatory pathways.

Molecular Characteristics and Biosynthesis

CXCL10 represents a sophisticated molecular entity with unique characteristics:

• Member of the CXC chemokine family
• Encoded by the CXCL10 gene
• Comprises 98 amino acids
• Molecular weight approximately 11.7 kDa
• Characterized by a highly conserved structural motif

Key structural features include:

• ELR (Glutamate-Leucine-Arginine) motif absent
• High affinity for CXCR3 receptor
• Ability to form complex intermolecular interactions
• Rapid response to inflammatory stimuli

Activation and Production Mechanisms

The synthesis of CXCL10 is triggered by multiple physiological signals:

1. Interferon-γ (IFN-γ) stimulation
2. Inflammatory cytokine activation
3. Viral and bacterial infections
4. Oxidative stress
5. Cellular damage responses

Primary production sites:

1. Endothelial cells
2. Fibroblasts
3. Epithelial cells
4. Monocytes
5. Activated immune cells
