Chemokine (C-X-C motif) ligand 2(CXCL2) is a smallcytokinebelonging to the CXCchemokinefamily that is also calledmacrophage inflammatory protein 2-alpha(MIP2-alpha),Growth-regulated protein beta(Gro-beta) andGro oncogene-2(Gro-2). CXCL2 is 90% identical inamino acidsequence as a related chemokine,CXCL1.This chemokine is secreted bymonocytesandmacrophagesand ischemotacticforpolymorphonuclear leukocytesandhematopoietic stem cells.[5][6][7]The gene for CXCL2 is located on humanchromosome 4in a cluster of other CXC chemokines.[8]CXCL2 mobilizes cells by interacting with a cell surfacechemokine receptorcalledCXCR2.[7]

CXCL2, like related chemokines, is also a powerful neutrophil chemoattractant and is involved in many immune responses including wound healing, cancer metastasis, and angiogenesis.[9]A study was published in 2013 testing the role of CXCL2, CXCL3, and CXCL1 in the migration of airway smooth muscle cells (ASMCs) migration which plays a significant role in asthma. The results of this study showed that CXCL2 and CXCL3 both help with the mediation of normal and asthmatic ASMC migration through different mechanisms.[9]

Clinical development

[edit]

CXCL2 in combination with theCXCR4inhibitorplerixaforrapidly mobilizeshematopoietic stem cellsinto the peripheral blood.[10]

This rapidperipheral blood stem cellmobilization regimen enteredPhase 2 clinical trialsin 2021[11][12]in development by Magenta Therapeutics[13]as a new method to collect stem cells forbone marrow transplantation.
