Dendritic-cell activation by secretory phospholipase A2.
Dendritic cells (DCs), also referred to as the sentinels of the immune system, induce and coordinate important functions of immune surveillance. DCs acquire immunity-initiating capacity only after a process of maturation usually induced by ligands that bind to members of the tumor necrosis factor (TNF) or toll-like receptor families. Secretory phospholipase A2 (sPLA2), which hydrolyzes the sn-2...
متن کاملInvolvement of cytosolic phospholipase A2 and secretory phospholipase A2 in arachidonic acid release from human neutrophils.
The purpose of this study was to define the role of secretory phospholipase A2 (sPLA2), calcium-independent PLA2, and cytosolic PLA2 (cPLA2) in arachidonic acid (AA) release from fMLP-stimulated human neutrophils. While fMLP induced the release of extracellular sPLA2 activity and AA, 70% of sPLA2 activity remained associated with the cell. Treatment with the cell-impermeable sPLA2 inhibitors DT...
متن کاملQuercetin as an inhibitor of snake venom secretory phospholipase A2.
As polyphenolic compounds isolated from plants extracts, flavonoids have been applied to various pharmaceutical uses in recent decades due to their anti-inflammatory, cancer preventive, and cardiovascular protective activities. In this study, we evaluated the effects of the flavonoid quercetin on Crotalus durissus terrificus secretory phospholipase A2 (sPLA2), an important protein involved in t...
متن کاملSecretory phospholipase A2: a multifaceted family of proatherogenic enzymes.
Secretory phospholipase A(2) (sPLA(2)) represents a class of enzymes that hydrolyze phospholipids from cellular membranes and lipoproteins, resulting in multifarious proatherogenic actions in the vessel wall. Proatherogenic actions of sPLA(2) involve lipoprotein remodeling that facilitates proteoglycan binding and formation of lipid aggregates that are rapidly internalized by tissue macrophages...
متن کاملSecretory phospholipase A2 in the pathogenesis of acute dengue infection
INTRODUCTION Platelet activating factor (PAF) is an important mediator of vascular leak in acute dengue. Phospholipase A2s (PLA2) are inflammatory lipid enzymes that generate and regulate PAF and other mediators associated with mast cells. We sought to investigate if mast cell activation and increases in secretory sPLA2s are associated with an increase in PAF and occurrence of dengue haemorrhag...
