eicosanoids การใช้

• Endogenous ligands for the PPARs include free fatty acids and eicosanoids.
• EFA sources : Essential fatty acid production and metabolism to form eicosanoids.
• The three types of eicosanoids are prostaglandins, thromboxanes, and leukotrienes.
• This enzyme is important in the production eicosanoids which are mediators of inflammation.
• In this way, synthesis of eicosanoids are inhibited.
• The eicosanoids are involved in multiple regulatory pathways.
• They are a subclass of eicosanoids and of the prostanoid class of fatty acid derivatives.
• They are a subclass of eicosanoids and form the prostanoid class of fatty acid derivatives.
• After oxidation, the eicosanoids are further modified, making a " series ".
• Hormones can consist of either amino acid complexes, steroids, eicosanoids, leukotrienes, or prostaglandins.
• The actions of eicosanoids within the brain are not as well characterized as they are in inflammation.
• LPS acts as the prototypical endotoxin because it binds the inflammatory cytokines, nitric oxide, and eicosanoids.
• For example, both AA-derived thrombaxane and leukotriene B4 are proaggregatory and vasoconstrictive eicosanoids during inflammation.
• The enzyme catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid which is subsequently metabolized into eicosanoids.
• Activated I 1-imidazoline receptors trigger the hydrolysis of phosphatidylcholine into second messengers arachidonic acid and downstream eicosanoids.
• By 1979 more of what are now known as eicosanoids were discovered : thromboxanes, prostacyclins, and the leukotrienes.
• In general, the eicosanoids derived from AA promote inflammation, and those from EPA and from pro-resolving.
• Cytosolic phospholipase A2-? acts on membrane phospholipids to release arachidonic acid a precursor in the synthesis of eicosanoids.
• If the rate of synthesis exceeds the rate of metabolism, the excess eicosanoids may, however, have deleterious effects.
• Researchers found that certain omega-3 fatty acids are also converted into eicosanoids, but at a much slower rate.
