Advanced Science, EarlyView.A microfluidic electrochemical biosensor enables sensitive and specific detection of antibodies associated with vaccine‐induced immune thrombotic thrombocytopenia (VITT) and heparin‐induced thrombocytopenia (HIT). The platform uses two antigen targets— platelet factor 4 (PF4) and cross‐linked‐PF4 (c‐PF4)—and microliter volumes of patient sera to ...

Platelet-activating factor antagonists
Clinical Reviews in Allergy, 1995The great number of PAF antagonists reviewed in this article clearly shows the tremendous effort made in the last 20 yr to explore the complex biological background of the mechanism of action of PAF and the potential clinical benefit of its antagonists. It is obvious that now highly potent, long-acting, and perorally applicable PAF-receptor antagonists

Platelet-activating factor (PAF) is a potent mediator that occurs at very low concentrations in cells and tissues. Accurate quantitation of PAF has always been difficult because of the physicochemical properties of PAF and its structural similarity to several much more abundant phospholipids.

Platelet-activating factor receptor
Prostaglandins & Other Lipid Mediators, 2002Platelet-activating factor (PAF, 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is a biologically active phospholipid mediator. Although PAF was named for its potential to induce platelet aggregation, intense investigations have elucidated potent biological actions of PAF in a broad range of cell types and tissues.

Platelet-Activating Factor Antagonists
Annual Review of Pharmacology and Toxicology, 1987Over the past decade platelet-activating factor has achieved the status of an important inflammatory mediator. The scientific enthusiasm and number of research investigators, publications, and meetings recently devoted to PAF suggest that this mediator will be the subject of continued study in the foreseeable future.

Radioimmunoassay for platelet‐activating factor
Lipids, 1991AbstractA radioimmunoassay (RIA) for measurement of platelet‐activating factor (PAF) was developed. At a final antiserum dilution of 1∶640, the lowest detection limit of PAF was 0.1 pmol (50 pg). The standard curve obtained was suitable for measurement of PAF in amounts ranging from 0.1 pmol to 30 pmol. The antiserum showed high specificity.

Our ability to chemically characterize and synthesize this autacoid of allergy and inflammation has given us a unique opportunity to study these important molecules in a highly disciplined fashion. It has also opened the door to a vista of research approaches to define PAF's normal physiologic role as well as its actions as an immunopathologic mediator.

Platelet Activating Factor Receptors
2003Platelet activating factor (PAF) is a potent pro-inflammatory lipid mediator. Its effects are mediated through cell surface G protein-coupled receptors (GPCRs) that are distributed on numerous cells notably on endothelium [1]. An intracrine mode of action for PAF is proposed based on evidence for intracellular PAF binding sites [2] and retention of ...

Platelet-activating factor (PAF) is a proinflammatory lipid. It has been strongly implicated in the regulation of pancreatic exocrine secretion and in the local and systemic events which occur in acute pancreatitis. PAF antagonists, when given as pretreatment, ameliorate the severity of experimental acute pancreatitis by reducing serum amylase ...
