Yet another benefit of omega-3 fats

NPD1 inhibits genes causing inflammation and cell death that oxidative stress and other triggers turn on. RPE cells contain the omega-3 fatty acid family member, DHA, which Dr. Bazan and colleagues found is a precursor to NPD1. RPE cells regulate the uptake, conservation, and delivery of DHA to the photoreceptor cells. DHA, known to be in short supply in patients with retinitis pigmentosa and Usher's syndrome, promotes protective cell signaling by facilitating the expression of helpful rather than destructive proteins as well as stimulating the production of NPD1. DHA and NPD1 also decrease the production of damaging free radicals. DHA has been shown by Dr. Bazan to promote survival and inhibit cell death not only of photoreceptor cells, but also of neurons in an experimental model of Alzheimer's disease.
