Chemokine (C motif) ligand 2 (XCL2) is a small cytokine belonging to the XC chemokine family that is highly related to another chemokine called XCL1.[1] It is predominantly expressed in activated T cells, but can also be found at low levels in unstimulated cells. XCL2 induces chemotaxis of cells expressing the chemokine receptorXCR1.[2] Its gene is located on chromosome 1 in humans.[3]
