Neuronal cell membrane phospholipids

Neuronal cell membrane phospholipids are the fundamental building blocks of the neuronal lipid bilayer, primarily consisting of phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine. These lipids are crucial for maintaining the structural integrity and optimal fluidity of neuronal membranes, which directly influences the activity of embedded receptors, ion channels, and transporters [1][2]. Beyond their structural role, they serve as precursors for vital secondary messengers involved in intracellular signaling and inflammatory responses [3]. In pathological states such as Alzheimer's disease or acute stroke, the degradation of these phospholipids leads to membrane instability, synaptic dysfunction, and eventual neuronal death [4]. Pharmacological strategies often focus on supplying precursors like citicoline to stimulate phospholipid synthesis or utilizing polyunsaturated fatty acids to restore membrane composition and neuroprotective signaling [5]. Additionally, the lipid environment of the neuronal membrane is known to modulate the sensitivity and kinetics of various neurotransmitter receptors, making it an indirect target for anesthetic agents [6].
