At the end of this cascade, a group of enzymes called Matrix Metallo Proteinases (MMPâs) are released. What Are MMPâs (Matrix Metallo Proteinases)? Matrix Metallo Proteinases (MMPâs) are enzymes that break down tissue. After an injury or âinsultâ to skin, the bodyâs natural response is to destroy the injured tissue and create new tissue. MMPâs are needed for remodeling skin in wound healing. This make sense if there is a real wound, such as a cut from a knife.
Myelin basic protein (MBP) is a protein believed to be important in the process of myelination of nerves in the nervous system. The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the velocity of axonal impulse conduction.MBP maintains the correct structure of myelin, interacting with the lipids in the myelin membrane.he protein encoded by the classic MBP gene is a major constituent of the myelin sheath of oligodendrocytes and Schwann cells in the nervous system. However, MBP-related transcripts are also present in the bone marrow and the immune system.
