Lysophospholipids are phospholipids that have just one fatty acid chain, and in recent years, the role of lysophospholipids in physiology and pathophysiology has attracted attention. Lysophosphatidylethanolamine (LPE) is a type of lysophospholipid that is reportedly present in the brain that consists of many species with different fatty acid chain lengths and degrees of unsaturation. The latest studies in animal models have reported elevated levels of LPE in the brain after traumatic brain injury and cerebral ischemia. Fluctuations in LPE concentration have also been reported in the plasma of patients with major depression and Alzheimer’s disease. Although these reports suggest the involvement of LPE in brain function, the role of LPE in the brain has remained unclear.
