Lyso-PAF C-16 can be formed by either the action of PAF-AH on PAF C-16, or by the action of a CoA-independent transacylase on 1-O-hexadecyl-2-acyl-glycerophosphocholine. Lyso-PAF C-16 is a substrate for either PAF C-16 formation by the remodeling pathway or selective acylation with arachidonic acid by a...

PAF C-16 is a naturally occurring phospholipid produced upon stimulation through two distinct pathways known as the "remodeling" and 'de novo' pathways. It is a potent mediator of neutrophil migration, and the production of reactive oxygen species, and IL-6 in human macrophages. It is a more potent mediator of...

PAF C-18 is a naturally occurring phospholipid produced upon stimulation through two distinct pathways known as the "remodeling" and 'de novo' pathways. It is less potent than PAF C-16 in the induction of platelet aggregation, but equipotent in activation of guinea pig macrophages. PAF C-18 induces the release of...

Hexadecyl acetyl glycerol (HAG) is an analog of DAG, which inhibits the activation of PKC by DAG. It also inhibits the growth of HL-60 cells and induces differentiation to cells resembling mononuclear phagocytes. Following treatment with 5 µg/ml HAG for six days, HL-60 cells demonstrated a 10-fold increase in...
