Abstract: A unique DHA product, 10, 17S-docosatriene (“Neuroprotectin D1” or “NPD1”), was found to provide surprisingly effective neuroprotection when administered right after an experimental stroke. Moreover, both nerve cells and retinal pigment epithelial (RPE) cells were found to synthesize 10,17S-docosatriene (NPD1) from DHA. NPD1 also potently counteracted H2O2/TNF? oxidative stress-mediated cell apoptotic damage. Under the same oxidative-stress conditions, NPD1 up-regulated the anti-apoptotic Bcl-2 proteins, Bcl-2 and Bcl-xL, and decreased expression of the pro-apoptotic proteins, Bad and Bax. Moreover, in RPE cells NPD1 inhibited oxidative stress-induced caspase-3 activation, IL-1?-stimulated human COX-2 promoter expression, and apoptosis due to N-retinylidene-N-retinylethanolamine (A2E). Overall, NPD1 protected both nerve and retinal pigment epithelial cells from cellular apoptosis and damage due to oxidative stress.
