WebA characteristic feature of mouse models of the peripheral neuropathies caused by dominant mutations in peripheral myelin protein 22 (pmp22) is the appearance, in Schwann cells, of pmp22 aggregates. Using a set of dominant and recessive pmp22 mutations that cause human disease of varying degrees of … Myelin is formed in the central nervous system (CNS; brain, spinal cord and optic nerve) by glial cells called oligodendrocytes and in the peripheral nervous system (PNS) by glial cells called Schwann cells. In the CNS, axons carry electrical signals from one nerve cell body to another. Meer weergeven Myelin is a lipid-rich material that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed … Meer weergeven Myelin is considered a defining characteristic of the jawed vertebrates (gnathostomes), though axons are ensheathed … Meer weergeven The main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the … Meer weergeven Demyelination Demyelination is the loss of the myelin sheath insulating the nerves, and is the hallmark of some neurodegenerative autoimmune diseases, … Meer weergeven The process of generating myelin is called myelination or myelinogenesis. In the CNS, oligodendrocyte progenitor cells (OPCs) differentiate into mature oligodendrocytes, which form … Meer weergeven CNS myelin differs slightly in composition and configuration from PNS myelin, but both perform the same "insulating" function (see above). Being rich in lipid, myelin appears white, hence the name given to the "white matter" of the CNS.
