Class A CpG Oligonucleotide Priming Rescues Mice from Septic Shock via Activation of Platelet-Activating Factor Acetylhydrolase

Frontiers in Immunology, 2017
Sepsis is a life-threatening, overwhelming immune response to infection with high morbidity and mortality. Inflammatory response and blood clotting are caused by sepsis, which induces serious organ damage and death from shock.

Lipopolysaccharide and platelet-activating factor stimulate expression of platelet-activating factor acetylhydrolase via distinct signaling pathways

, 2011
This study was designed to investigate and characterize the ability of platelet-activating factor (PAF) to induce the expression of platelet-activating factor acetylhydrolase (PAF-AH).Ribonuclease protection assays and quantitative real-time PCR were ...

Platelet-activating factor acetylhydrolase (PAF-AH) in human kidney

International Journal of Biochemistry, 1994
1. PAF-AH activity in human kidney (cortex and medulla) has been demonstrated and shares the following properties. 2. Does not require the presence of Ca2+ and appears to be different from phospholipase A2. 3. The pH optimum shows a peak at 7-7.4. 4. It is stable for 4 days at -30 degrees C. 5. It is mainly distributed in the microsomal fraction.

Synthetic studies on platelet-activating factor (PAF).

Chemical and Pharmaceutical Bulletin, 1985
Chemical synthesis of platelet-activating factor (PAF, 1) and its enantiomer was studied. Several alkoxymethyl alkenyl ketones (5a-c, n=14 or 16) were synthesized from Wittig-Horner reagents (4, n=14 or 16) with cyclohexanecarboxaldehyde, octylaldehyde, and benzaldehyde, and subjected to asymmetric reduction with BINAL-H1) which is known to show high ...

Receptor mechanisms of PAF mediated lymphatic constriction in the canine forelimb

Mediators of Inflammation, 1992
Platelet activating factor (PAF) is a potent inflammatory lipid. In this study we assessed the ability of PAF to impact lymphatic vessel function by altering prenodal lymphatic resistance.
