General description

MIP-2 (microphage inflammatory protein-2), or Cxcl2 ((C-X-C motif) ligand 2), was initially recognized as a 6kDa protein released by an LPS (lipopolysaccharide)-stimulated mouse macrophage cell line. It belongs to the chemokine family which contains 6-14kDa, heparin-binding cytokines. It is a member of the a (CXC) chemokine family, where any amino acid separates both conserved cysteines.
Mouse MIP-2 is a 7.8kDa protein containing 73 amino acid residues including the ‘RLR′ motif common to the CXC chemokine family that bind to CXCR1 or CXCR2.

Biochem/physiol Actions

MIP-2 (microphage inflammatory protein-2), or Cxcl2 ((C-X-C motif) ligand 2), is a functional homolog of human IL-8 (interleukin) in mice, and like human IL-8 it induces a potent neutrophil chemotactic activity. It might be critical in the recruitment and influx of immune cells in inflammation and infection. Murine encephalomyelitis virus of Theiler (TMEV) induces the expression of MIP-2 in genetically susceptible but not in resistant mouse strains. In mice, in acute and chronic liver injury, TLR2 (Toll-like receptor)/S100A9/MIP-2 signaling pathways is crucial for neutrophil recruitment, and this might have therapeutic implications in selectively manipulating neutrophils in liver disease while circumventing normal wound healing and regenerative responses.

Physical form

Sterile filtered and then lyophilized without additives.

Reconstitution

Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.

Chronic otitis media with effusion is characterized by middle ear secretion of mucin glycoproteins, predominantly MUC5B; MUC5AC, the other secretory mucin studied frequently, has also been identified in the middle ear. Emerging evidence suggests a dichotomous role for these mucins

Immune cell chemotaxis to the sites of pathogen invasion is critical for fighting infection, but in life-threatening conditions such as sepsis and Covid-19, excess activation of the innate immune system is thought to cause a damaging invasion of immune cells

Excessive neutrophil activation is a major component in septic lung injury. Neutrophil-derived DNA may form extracellular traps in response to bacterial invasions. The aim of the present study was to investigate the potential role of neutrophil extracellular traps (NETs) in
