Lipids,defined by low solubility in water and high solubility in nonpolar solvents,can be classified into fatty acids,glycerolipids,glycerophospholipids,sphingolipids,and sterols.Lipids not only regulate integrity and fluidity of biologi-cal membranes,but also serve as energy storage and bioactive molecules for signaling.Causal mutations in SPTLC1(serine palmitoyltransferase long chain subunit 1)gene within the lipogenic pathway have been identified in amyo-trophic lateral sclerosis(ALS),a paralytic and fatal motor neuron disease.Furthermore,lipid dysmetabolism within the central nervous system and circulation is associated with ALS.Here,we aim to delineate the diverse roles of different lipid classes and understand how lipid dysmetabolism may contribute to ALS pathogenesis.Among the different lipids,accumulation of ceramides,arachidonic acid,and lysophosphatidylcholine is commonly emerging as detri-mental to motor neurons.We end with exploring the potential ALS therapeutics by reducing these toxic lipids. 展开更多
