Chemokine
Chemokine — A family of small cytokine-like proteins that guide the migration of immune cells through chemotaxis, studied in peptide-based immunology research.
What Is a Chemokine?
Chemokines are a family of small (8-12 kDa) chemoattractant cytokines that direct immune cell migration through concentration gradients. They are classified by cysteine motifs: CC (MCP-1, RANTES), CXC (IL-8, SDF-1), CX3C (fractalkine), and C (lymphotactin). Chemokine-derived peptides and receptor antagonists are active areas of peptide drug discovery.
Peptide Connections
- N-terminal peptides: Chemokine N-terminal fragments often retain receptor binding activity
- CXCR4 antagonists: Peptide antagonists (T140, BKT140) blocking SDF-1/CXCR4 axis in cancer stem cell mobilization
- LL-37: Functions as a chemokine, recruiting immune cells via FPR2
