The neutrophil has been implicated as an important mediator of vascular injury, especially after endotoxemia. This study examines neutrophil-mediated injury to human microvascular endothelial cells in vitro. We found that neutrophils stimulated by formyl-methionyl-leucyl-phenylalanine (FMLP), the complement fragment C5a, or...

The mature neutrophils in the circulation contain, besides the different proteases known for a long time, a recently discovered proteolytically inactive elastase homologue (HBP/CAP37/azurocidin). This homologue, which we have named HBP due to its strong affinity to heparin, is a...

Neutrophils play an important role in innate immunity by defending the host organism against invading microorganisms. Antimicrobial activity of neutrophils is mediated by release of antimicrobial peptides, phagocytosis as well as formation of neutrophil extracellular traps (NET). These structures are...

Previously published work has indicated that polyunsaturated fatty acids (PUFA) may enhance neutrophil-mediated damage to host tissues. We have found that endothelial detachment was significantly increased by neutrophils pretreated with docosahexaenoic (22:6, n-3) and arachidonic (20:4, n-6) acids at 10-40...

The role of elastase and proteinase inhibitors in polymorphonuclear leukocyte(PMN)-mediated injury to human umbilical cord venous endothelial cells (HUVEC) was investigated. Both purified human neutrophil elastase and PMN that were stimulated with serum-treated zymosan (STZ) induced detachment, but not lysis...

Incubation of polymorphonuclear cells (PMN), isolated from human peripheral blood, with either lipoprotein(a) (Lp(a)) or free apolipoprotein(a) (apo(a)), derived from the parent Lp(a), caused in both cases a multisite fragmentation of apo(a) inhibited by methoxysuccinyl-Ala-Ala-Pro-Val-CH2Cl, a specific elastase inhibitor. The...
