Neuronal and glial cell membranes

Neuronal and glial cell membranes are the complex lipid bilayer structures that define the boundaries of cells within the nervous system. These membranes serve as the essential scaffold for a vast array of functional proteins, including ion channels, G protein-coupled receptors, and transporters, which are vital for electrical signaling and neurotransmission (StatPearls, 2023). In neurodegenerative conditions like Alzheimer's disease, the integrity of these membranes is often compromised by lipid peroxidation or changes in cholesterol content, leading to synaptic dysfunction (PubMed, PMID: 31510507). While historically considered a target for general anesthetics via the 'lipid theory' of anesthesia, modern pharmacology typically focuses on specific protein components within these membranes. However, certain neuroprotective strategies still aim to stabilize or repair these membranes using phospholipid precursors or omega-3 fatty acids to maintain cellular homeostasis and connectivity.
