Platelet-activating factor, also known as PAF, PAF-acether or AGEPC (acetyl-glyceryl-ether-phosphorylcholine), is a potent phospholipid activator and mediator of many leukocyte functions, platelet aggregation and degranulation, inflammation, and anaphylaxis. It is also involved in changes to vascular permeability, the oxidative burst ...
Platelet-activating factor receptor. The platelet-activating factor receptor (PAF-R) is a G-protein coupled receptor which binds platelet-activating factor. [5] [6] It is encoded in the human by the PTAFR gene. The PAF receptor shows structural characteristics of the rhodopsin (MIM 180380) gene family and binds platelet-activating factor (PAF).
Lipoprotein-associated phospholipase A 2 (Lp-PLA2) also known as platelet-activating factor acetylhydrolase (PAF-AH) is a phospholipase A 2 enzyme that in humans is encoded by the PLA2G7 gene. [5][6] Lp-PLA 2 is a 45-kDa protein of 441 amino acids. [7] It is one of several PAF acetylhydrolases.
Atrial fibrillation (AFib) is a type of irregular heartbeat. If you have it, your doctor will classify yours by the reason for it and on how long it lasts. When your heartbeat returns to normal ...
6 min read. It’s easy to confuse atrial fibrillation (AFib) with what’s called supraventricular tachycardia (SVT). After all, both have to do with your heart rate and both start in the upper ...
Paroxysmal atrial fibrillation (AFib) is a type of AFIB that happens without an obvious trigger and stops just as spontaneously. These episodes can last from a few minutes to a few days. Around 40 ...
Paroxysmal atrial tachycardia (PAT) is a form of arrhythmia in which an abnormally fast heartbeat starts and ends abruptly from your heart’s upper chambers. Lifestyle changes can reduce your ...
