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 in allergies

International Journal of Immunopathology and Pharmacology, 2015
The platelet-activating factor (PAF) produced and released by mast cells, basophils, neutrophils, eosinophils, fibroblasts, platelets, endothelial cells, and even cardiac muscle cells plays an important role in inflammatory and thrombotic diseases. PAF has been shown to be an important mediator in anaphylaxis. Serum level of the factor correlates with

Anti–platelet factor 4 antibodies causing VITT do not cross-react with SARS-CoV-2 spike protein

Blood, 2021
Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a severe adverse effect of ChAdOx1 nCoV-19 COVID-19 vaccine (Vaxzevria) and COVID-19 vaccine Janssen (Ad26.COV2.S), and associated with unusual thrombosis.

Regulating inflammation through the anti-inflammatory enzyme platelet-activating factor-acetylhydrolase

Memorias do Instituto Oswaldo Cruz, 2005
Platelet-activating factor (PAF) is one of the most potent lipid mediators involved in inflammatory events. The acetyl group at the sn-2 position of its glycerol backbone is essential for its biological activity.

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 ...
