Mast cells are present in human lung tissue interspersed within the pulmonary epithelium and can secrete a host of pre- and newly formed mediators from their granules, which may propagate small airway inflammation. In this study, tryptase stimulation of HSAEC increased membrane-associated, calcium-independent phospholipase A(2)gamma (iPLA(2)gamma) activity, resulting in increased arachidonic acid and PGE(2) release. These responses were inhibited by pretreating HSAEC with the iPLA(2)-selective inhibitor bromoenol lactone. The tryptase-stimulated PGE(2) production was inhibited by treating HSAEC with the cyclooxygenase (COX)-1-selective inhibitor SC-560 and the nonselective COX inhibitor aspirin but not by the COX-2-selective inhibitor CAY10404, indicating that the early release of arachidonic acid is metabolized by constitutive COX-1 to form PGE(2) in tryptase-stimulated HSAEC. Additionally, platelet-activating factor production and neutrophil adherence to tryptase-stimulated HSAEC was also increased. This complex response can set up a cascade of inflammatory mediator production in small airways. We speculate that selective inhibition of iPLA(2)gamma-mediated phospholipid hydrolysis may prove beneficial in inflammatory airway diseases."xsd:string |
