Polyunsaturated fatty acids (PUFAs) such as Arachidonic acid (AA), alpha-linolenic acid (ALA), docosahexaenoic acid (DHA) or lysophospholipids (LP) such as lysophosphatidylcholine (LPC) also activate TREK-1 channels and are neuroprotective against both ischemia and seizures induced by kainate injections [22], [29]. The gene discussed is KCNK2; the disease is ischemia.
