A Review of Platelet-Activating Factor As a Potential Contributor to Morbidity and Mortality Associated with Severe COVID-19

Clinical and Applied Thrombosis/Hemostasis, 2021
The precise mechanisms of pathology in severe COVID-19 remains elusive. Current evidence suggests that inflammatory mediators are responsible for the manifestation of clinical symptoms that precedes a fatal response to infection. This review examines the

Platelet activating factor receptor antagonists improve the efficacy of experimental chemo- and radiotherapy

Clinics, 2018
Platelet activating factor is a lipid mediator of inflammation, and in recent decades, it has emerged as an important factor in tumor outcomes. Platelet activating factor acts by specific binding to its receptor, which is present in both tumor cells and ...

Effect of montelukast on platelet activating factor- and tachykinin induced mucus secretion in the rat

Journal of Occupational Medicine and Toxicology, 2008
Background Platelet activating factor and tachykinins (substance P, neurokinin A, neurokinin B) are important mediators contributing to increased airway secretion in the context of different types of respiratory diseases including acute and chronic ...

Structural identification of oxidized acyl-phosphatidylcholines that induce platelet activation [PDF]

, 2005
Oxidation of low-density lipoprotein (LDL) generates proinflammatory and prothrombotic mediators that may play a crucial role in cardiovascular and inflammatory diseases.

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 ...

Platelet-activating factor acetyl hydrolase IB2 dysregulated cell proliferation in ovarian cancer

Cancer Cell International, 2021
Background Ovarian cancer is the leading cause of death from gynaecologic illnessed worldwide. Platelet-activating factor acetyl hydrolase IB2 (PAF-AH IB2) is an intracellular serine esterase that hydrolyzes platelet-activating factor, a G-protein-like ...

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.

Platelet activating factor revisited [PDF]

Thorax, 1997
8A2 and acetyltransferase on membrane alkylacyl phospholipids. PAF was found to possess many properties that made it well suited as a proinflammatory mediator of inflammation in many inflammatory diseases. 1 Interest in Degradation of PAF its potential role as a mediator of asthma was fuelled Being a potent bioactive mediator, it makes sense that PAF ...

Plasma PAF-acetylhydrolase in patients with coronary artery disease: results of a cross-sectional analysis

Journal of Lipid Research, 2003
Inflammation underlies both onset and perpetuation of atherosclerosis. Plasma lipoproteins transport the platelet-activating factor-acetylhydrolase (PAF-AH) with potentially anti-inflammatory activities.
