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.[3] 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.[4] Its
gene is located on
chromosome 1 in humans.[5]
