Target Background

This is a neutrophil granule-derived antibacterial and monocyte- and fibroblast-specific chemotactic glycoprotein. Binds heparin. The cytotoxic action is limited to many species of Gram-negative bacteria; this specificity may be explained by a strong affinity of the very basic N-terminal half for the negatively charged lipopolysaccharides that are unique to the Gram-negative bacterial outer envelope. It may play a role in mediating recruitment of monocytes in the second wave of inflammation. Has antibacterial activity against the Gram-negative bacterium P.aeruginosa, this activity is inhibited by LPS from P.aeruginosa. Acting alone, it does not have antimicrobial activity against the Gram-negative bacteria A.actinomycetemcomitans ATCC 29532, A.actinomycetemcomitans NCTC 9709, A.actinomycetemcomitans FDC-Y4, H.aphrophilus ATCC 13252, E.corrodens ATCC 23834, C.sputigena ATCC 33123, Capnocytophaga sp ATCC 33124, Capnocytophaga sp ATCC 27872 or E.coli ML-35. Has antibacterial activity against C.sputigena ATCC 33123 when acting synergistically with either elastase or cathepsin G.

  17. Azurocidin 1 (cationic antimicrobial protein 37)is a multifunctional inflammatory mediator causing an increase of vascular permeability [review]. PMID: 14515154
  18. Due to its localization to atherosclerotic plaques and its ability to modulate smooth muscle cells, CAP37 may play a role in the progression of this disease. PMID: 15020208
  19. Secretion of CAP37, a neutrophil granule protein accumulating on the endothelial cell surface and promoting arrest of monocytes, could contribute to the recruitment of monocytes at inflammatory loci. PMID: 15879141
  20. HBP appears to be one of the primary effector molecules of antibody-mediated nonhemolytic transfusion reactions including transfusion acute lung injury PMID: 18346022
  21. HBP and human neutrophil peptides 1-3 triggered macrophage release of TNF-alpha and IFN-gamma, which acted in an autocrine loop to enhance expression of CD32 and CD64 and thereby enhance phagocytosis[heparin-binding protein, HBP] PMID: 18787642
  22. Data show that human neutrophils challenged with leukotriene B(4) release heparin-binding protein as determined by Western blot analysis. PMID: 19151333
