Prostaglandin E2 Prevents Hyperosmolar-Induced Human Mast Cell Activation through Prostanoid Receptors EP2 and EP4
BACKGROUND Mast cells play a critical role in allergic and inflammatory diseases, including exercise-induced bronchoconstriction (EIB) in asthma. The mechanism underlying EIB is probably related to increased airway fluid osmolarity that activates mast cells to the release inflammatory mediators. These mediators then act on bronchial smooth muscle to cause bronchoconstriction. In parallel, prote...
متن کاملReceptors and signaling mechanisms required for prostaglandin E2-mediated regulation of mast cell degranulation and IL-6 production.
Mast cells are implicated in the pathogenesis of a broad spectrum of immunological disorders. These cells release inflammatory mediators in response to a number of stimuli, including IgE-Ag complexes. The degranulation of mast cells is modified by PGs. To begin to delineate the pathway(s) used by PGs to regulate mast cell function, we examined bone marrow-derived mast cells (BMMC) cultured from...
متن کاملProstaglandin E2 induces degranulation-independent production of vascular endothelial growth factor by human mast cells.
Mast cells accumulate in large numbers at angiogenic sites, where they have been shown to express a number of proangiogenic factors, including vascular endothelial growth factor (VEGF-A). PGE(2) is known to strongly promote angiogenesis and is found in increased levels at sites of chronic inflammation and around solid tumors. The expression pattern of VEGF and the regulation of VEGF-A by PGE(2)...
متن کاملProstaglandin E2 is generally required for human dendritic cell migration and exerts its effect via EP2 and EP4 receptors.
The control of dendritic cell (DC) migration is pivotal for the initiation of cellular immune responses. In this study, we demonstrate that the migration of human monocyte-derived (Mo)DCs as well as of ex vivo peripheral blood DCs toward CCL21, CXCL12, and C5a is stringently dependent on the presence of the proinflammatory mediator PGE2, although DCs expressed CXCR4 and C5aR on their surface an...
متن کاملProstaglandin E2 promotes degranulation-independent release of MCP-1 from mast cells.
Mast cells (MCs) are common components of inflammatory infiltrates and a source of proangiogenic factors. Inflammation is often accompanied by vascular changes. However, little is known about modulation of MC-derived proangiogenic factors during inflammation. In this study, we evaluated the effects of the proinflammatory mediator prostaglandin E2 (PGE2) on MC expression and release of proangiog...
