WebThe eicosanoids formed play important roles in neural function including sleep induction (PGD2), long term potentiation, spatial learning and synaptic plasticity (PGE2), resolution of inflammation (lipoxins) and anti-inflammatory and neuroprotective bioactivity (dihydroxy-docosatriene, neuroprotectin D1, formed from DHA). Eicosanoids are signaling molecules made by the enzymatic or non-enzymatic oxidation of arachidonic acid or other polyunsaturated fatty acids (PUFAs) that are, similar to arachidonic acid, around 20 carbon units in length. Eicosanoids are a sub-category of oxylipins, i.e. oxidized fatty acids of diverse carbon units in length, and are distinguished from other oxylipins by their overwhelming importance as cell signaling molecules. Eicosanoids function in diverse physiologic…
