Chemokine (C-X-C motif) ligand 2 (CXCL2) is a small cytokine belonging to the CXC chemokine family that is also called macrophage inflammatory protein 2-alpha (MIP2-alpha), Growth-regulated protein beta (Gro-beta) and Gro oncogene-2 (Gro-2). CXCL2 is 90% identical in amino acid sequence as a related chemokine, CXCL1. This chemokine is secreted by monocytes and macrophages and is chemotactic for polymorphonuclear leukocytes and hematopoietic stem cells.^[5]^[6]^[7] The gene for CXCL2 is located on human chromosome 4 in a cluster of other CXC chemokines.^[8] CXCL2 mobilizes cells by interacting with a cell surface chemokine receptor called CXCR2.^[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

CXCL2 in combination with the CXCR4 inhibitor plerixafor rapidly mobilizes hematopoietic stem cells into the peripheral blood.^[10]

This rapid peripheral blood stem cell mobilization regimen entered Phase 2 clinical trials in 2021^[11]^[12] in development by Magenta Therapeutics^[13] as a new method to collect stem cells for bone marrow transplantation.
