Axonal protective effects of the myelin-associated glycoprotein.
Progressive axonal degeneration follows demyelination in many neurological diseases, including multiple sclerosis and inherited demyelinating neuropathies, such as Charcot-Marie-Tooth disease. One glial molecule, the myelin-associated glycoprotein (MAG), located in the adaxonal plasmalemma of myelin-producing cells, is known to signal to the axon and to modulate axonal caliber through phosphory...
متن کاملDisruption of the Gene for the Myelin-Associated Glycoprotein Improves Axonal Regrowth along Myelin in C57BL/Wlds Mice
The myelin-associated glycoprotein (MAG) has been shown to be inhibitory for certain neurons in vitro (Mukhopadhyay et al., 1994; McKerracher et al., 1994). To investigate whether MAG is an inhibitory component in peripheral myelin in vivo, MAG-deficient mutant mice were cross-bred with C57BL/Wlds mice that have delayed lesion-induced myelin degeneration and axon regrowth. While in crushed nerv...
متن کاملCytoplasmic Domains of the Myelin-associated Glycoprotein
The function of the vertebrate nervous system is based on the rapid and accurate transmission of electrical impulses. The myelin sheath is a lipid-rich membrane that envelops the axon, preventing the leakage of the nervous impulse to the environment. Myelin is formed when the plasma membrane of a myelinating glial cell differentiates and wraps around an axon. The compaction of myelin leads to t...
متن کاملMyelin-Oligodendrocyte Glycoprotein Antibodies Spectrum Disorders
Myelin-Oligodendrocyte Glycoprotein (MOG) is an adhesive molecule responsible for myelin sheath structural integrity and maintenance. Patients with spectrum of inflammatory demyelinating disease particularly in central nervous system are reported to have antibodies against this protein. Diseases such as multiple sclerosis, clinically isolated syndrome, neuro-myelitis optica (NMO) spectrum disor...
متن کاملBlockade of Nogo-66, myelin-associated glycoprotein, and oligodendrocyte myelin glycoprotein by soluble Nogo-66 receptor promotes axonal sprouting and recovery after spinal injury.
The growth of injured axons in the adult mammalian CNS is limited after injury. Three myelin proteins, Nogo, MAG (myelin-associated glycoprotein), and OMgp (oligodendrocyte myelin glycoprotein), bind to the Nogo-66 receptor (NgR) and inhibit axonal growth in vitro. Transgenic or viral blockade of NgR function allows axonal sprouting in vivo. Here, we administered the soluble function-blocking N...
