  Chemokine - Wikipedia, the free encyclopedia
All chemokines have molecular masses of between 8 and 10 kDa and are approximately 20-50% identical.
Chemokines are released from a wide variety of cells in response to bacterial infection, viruses and agents that cause physical damage such as silica or the urate crystals that occur in gout.
Members of the chemokine family fall mostly into two broad groups-CC chemokines (or β-chemokines) with two adjacent cysteines near the amino terminus of the protein, and CXC chemokines (or α-chemokines) in which the cysteines are separated by an amino acid.
