Platelet-Activating Factor Disrupts the Nasal Epithelial Barrier Independently of the Platelet-Activating Factor Receptor Pathway. [PDF]

Allergy Asthma Immunol Res
Platelet-activating factor (PAF) mediates nasal congestion and rhinorrhea by affecting vascular permeability, but the underlying mechanisms remain unclear. Here, we sought to explore the effect of PAF on the nasal epithelial barrier in chronic rhinosinusitis with nasal polyps (CRSwNP).Human nasal epithelial cells (hNECs) were pre-treated with Apafant ...

Interplay Between EGFR and the Platelet-Activating Factor/PAF Receptor Signaling Axis Mediates Aggressive Behavior of Cervical Cancer

Frontiers in Oncology, 2020
Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase widely expressed in cervical tumors, being correlated with adverse clinical outcomes. EGFR may be activated by a diversity of mechanisms, including transactivation by G-protein coupled

Platelet-activating factor: receptors and signal transduction [PDF]

Biochemical Journal, 1993
During the past two decades, studies describing the chemistry and biology of PAF have been extensive. This potent phosphoacylglycerol exhibits a wide variety of physiological and pathophysiological effects in various cells and tissues. PAF acts, through specific receptors and a variety of signal transduction systems, to elicit diverse biochemical ...

Platelet-Activating Factor-Induced Reduction in Contact Hypersensitivity Responses Is Mediated by Mast Cells via Cyclooxygenase-2-Dependent Mechanisms [PDF]

, 2018
Platelet-activating factor (PAF) stimulates numerous cell types via activation of the G protein-coupled PAF receptor (PAFR). PAFR activation not only induces acute proinflammatory responses, but it also induces delayed systemic immunosuppressive effects ...

Design, Synthesis and Anti-Platelet Aggregation Activity Study of Ginkgolide-1,2,3-triazole Derivatives

Molecules, 2019
Ginkgolides are the major active component of Ginkgo biloba for inhibition of platelet activating factor receptor. An azide-alkyne Huisgen cycloaddition reaction was used to introduce a triazole nucleus into the target ginkgolide molecules.

Pharmacologic modulation of experimental postischemic hepatic function [PDF]

, 1989
The present study, evaluated and compared the effects of SRI 63-441, a potent platelet activating factor antagonist, superoxide dismutase (SOD), an oxygen free radical scavenger, and ibuprofen, a cyclooxygenase inhibitor on hepatic function after 90 ...

To hydrolyze or not to hydrolyze: the dilemma of platelet-activating factor acetylhydrolase

Journal of Lipid Research, 2014
Mounting ambiguity persists around the functional role of the plasma form of platelet-activating factor acetylhydrolase (PAF-AH). Because PAF-AH hydrolyzes PAF and related oxidized phospholipids, it is widely accepted as an anti-inflammatory enzyme.

Protease-activated receptor 1 mediates thrombin-dependent, cell-mediated renal inflammation in crescentic glomerulonephritis. [PDF]

, 2000
Protease-activated receptor (PAR)-1 is a cellular receptor for thrombin that is activated after proteolytic cleavage. The contribution of PAR-1 to inflammatory cell-mediated renal injury was assessed in murine crescentic glomerulonephritis (GN).

Platelet lysate-derived neuropeptide y influences migration and angiogenesis of human adipose tissue-derived stromal cells [PDF]

, 2018
Neuropeptide Y (NPY), a powerful neurotransmitter of the central nervous system, is a key regulator of angiogenesis and biology of adipose depots. Intriguingly, its peripheral vascular and angiogenic powerful activity is strictly associated to platelets,
