Context: Scientists have developed monolayers of pure myelin basic protein (MBP) using the Langmuir-Blodgett technique to study the role of MBP in diseases such as multiple sclerosis.


About Myelin Sheath:

Definition A protective membrane that wraps around the axon of nerve cells in the Human body
Function Acts as an insulator, allowing for fast and efficient transmission of electrical signals along the nerve cells
Composition Consists of lipids and proteins, including myelin basic protein (MBP)
Importance Damage to the myelin sheath can lead to neurological disorders such as multiple sclerosis
About pure Myelin basic protein (MBP) MBP is a major protein component of the myelin sheath. It is responsible for the adhesion of the cytosolic surfaces (liquids found inside cells) of myelin.
About Multiple sclerosis It is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. In MS, the immune system attacks and damages the myelin sheath, leading to a variety of symptoms including muscle weakness, fatigue, balance problems, and vision loss.
