Central nervous system cell membranes

The term "central nervous system cell membranes" refers to the biological membranes that surround all cell types within the CNS, including neurons (nerve cells) and glial cells (supporting cells such as astrocytes, oligodendrocytes, microglia, and ependymal cells)[1][2][3][4][5]. These membranes are primarily composed of a phospholipid bilayer with embedded proteins, serving as selective barriers that control the entry and exit of ions, nutrients, and signaling molecules, maintain electrochemical gradients, and are studded with specific proteins such as receptors, ion channels, and transporters[2][6]. The specialization and composition of these membranes are critical to neuronal signaling, rapid conduction (via myelination), modulation of synaptic activity, and protection of CNS homeostasis[1][2][4]. Pathological changes in these membranes, due to genetic, autoimmune, or toxic processes, can lead to neurological diseases such as multiple sclerosis, where disruption of the myelin membrane leads to impaired nerve conduction[2][5]. However, "central nervous system cell membranes" does not denote a discrete molecular entity or recognizable pharmaceutical target.
