Definitions
- the present invention relates generally to the fields of pharmaceuticals, medical products, health care products, and food technology, and more particularly to mussel mucin products and their use in preventing and inhibiting neuroinflammation.
- the nervous system is a functional regulation system that plays a leading role in the human body. It is composed of brain, spinal cord, cranial nerve, spinal nerve and vegetative nerve, and various ganglia. It can coordinate the activities of various organs and systems in the body and make it complete. Integrated and interacted with the external environment.
- Neuroinflammation refers to the inflammation or deterioration of nerves or nerve groups.
- the symptoms vary with the disease. There are many causes of neuroinflammation, including nerve injuries such as nearby fractures and direct blows; nerve infections such as diabetes and blood cancer. And gout, etc.; mercury, lead, methanol and other poisoning; lack of vitamin B group in the diet, the general symptoms of neuroinflammation are pain, tenderness, tingling, infected nerve itching and loss of consciousness, partial infection of redness and severe spasm.
- Mussel adhesive protein also known as Mytilus edulis foot protein (Mefp)
- Mefp Mytilus edulis foot protein
- Mytilus coruscus A special protein secreted by Perna viridis. Mussels are usually attached in groups to the reefs on the coast or to the bottom of the ship, and have the ability to withstand wave impacts in the offshore. In fact, mussels can be attached extremely strongly to the substrate of any material, such as metal, wood, glass, and the like. The main reason for the above characteristics of mussels is that they can form and store this special mucin in the girth of the foot. The mussels release the mucin through the foot silk to a solid surface such as rock to form a water-resistant combination. Fix yourself.
- Mussel mucin has two structural features: (1) containing lysine, which has a high loading of positive charge; and (2) containing 3,4 dihydroxyphenylalanine (DOPA, dopa). The cells and tissues of the human body are negatively charged.
- Mussel mucin interacts with cells by electrostatic interaction between its own positive charge and the negative charge of human cells and tissues Closely integrated with the organization to play a protective and therapeutic role.
- dopa oxidation produces ortho-dioxins, which can be cross-linked with unoxidized dopa to form a membrane or a network scaffold, which promotes the protein to adhere more closely and firmly to the surface of the human body, thereby protecting.
- Mussel mucin is a macromolecular protein that is completely degraded in the human body for about 3-10 days. Its ability to attach to cell tissues is excellent, so that mussel mucin can be stabilized locally and continue to function.
