Chemokines (or chemotactic cytokines, chemoattractant cytokines) are a large family of small, highly conserved cytokines (8 to 12 kDa) with chemotactic activity. Chemokines mediate the migratory patterns and positioning of all immune cells and are critical for the function of the innate immune system. They are usually categorized into four main subfamilies according to the location of N-terminal cysteine residues: CC, CXC, CX3C and C. Chemokine signals are transduced through binding to G protein-coupled receptor (GPCR) superfamily. Chemokines receptors are divided into four families based on the binding-chemokine type: receptors for CC (CCR), CXC (CXCR), C (XCR1), and for CX3C (CX3CR1). The chemokine signaling network is composed of approximately 50 secreted ligands and 20 GPCRs. Research has shown that this complex system is involved in a variety of physiological processes including mediation of cellular migration during immune responses.
