摘要

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease affecting the adult motor system, with no effective treatments available. Despite extensive research efforts, the exact pathological cascade leading to progressive motor neuron degeneration remains elusive. Recent evidence highlights significant modifications in lipid metabolism during ALS progression, even before the onset of motor symptoms. Glycerophospholipids, the primary components of cellular membranes, are frequently altered in ALS patients and models. These lipids not only play a structural role in membranes, but also contribute to cellular metabolism, signaling pathways, and cell type-specific processes such as neuronal transmission and muscle contraction. In this review, we discuss glycerophospholipid physiological functions in the motor system and review recent studies demonstrating their alterations and the possible underlying pathological mechanisms in ALS. Furthermore, we discuss challenges emerging from studying lipid alterations in neurodegeneration and evaluate the therapeutic potential of glycerophospholipids.
