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 platelet aggregation than PAF C-18. Pathological processes involving PAF include necrotizing enterocolitis, inflammation, asthma, and allergy.
