Transcellular biosynthesis of sulfidopeptide leukotrienes during receptor-mediated stimulation of human neutrophil/platelet mixtures.
The ability of different cell types to cooperate in the metabolism of reactive intermediates of arachidonic acid such as leukotriene A4 (LTA4) is currently receiving considerable attention. Of critical importance is the demonstration that transfer of LTA4 could occur under conditions when relatively low amounts of LTA4 are produced such as would be expected for in vitro receptor-mediated stimul...
متن کاملThe effect of ketamine on NMDA receptor-mediated LTP depends on ketamine effects on non-NMDA-mediated synaptic transmission in CA1 area of rat hippocampal slices
It has been reported that ketamine as an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist has also non-NMDA receptor antagonist properties. We recently found that ketamine (20 ?M) affected differently induction of NMDA receptor-mediated long-term potentiation (LTP) when administered 30 min prior to tetanic Primed-Bursts (PBs) stimulation. On the other hand, ketamine also influenced...
متن کاملHuman neutrophil peptides mediate endothelial-monocyte interaction, foam cell formation, and platelet activation.
OBJECTIVE Neutrophils are involved in the inflammatory responses during atherosclerosis. Human neutrophil peptides (HNPs) released from activated neutrophils exert immune modulating properties. We hypothesized that HNPs play an important role in neutrophil-mediated inflammatory cardiovascular responses in atherosclerosis. METHODS AND RESULTS We examined the role of HNPs in endothelial-leukocy...

متن کاملPlatelets stimulated by IgG-coated surfaces bind and activate neutrophils through a selectin-dependent pathway.
Blood platelets bind rapidly to foreign surfaces and interact with adsorbed proteins and neutrophil granulocytes. We demonstrate by use of luminol-amplified chemiluminescence under stirred and non-stirred conditions that platelets at IgG-coated surfaces amplify the neutrophil extracellular release of reactive oxygen species (ROS). The neutrophil response involved tyrosine phosphorylation, but w...
