Myelin sheath of a healthy neuron in the central nervous system. Multiple sclerosis is an inflammatory demyelinating disease of the CNS in which activated immune cells invade the central nervous system and cause inflammation, neurodegeneration, and tissue damage. The underlying cause is currently unknown.
It also seems that myelin basic protein (MBP) from multiple sclerosis (MS) patients contains lower levels of phosphorylation at Thr97 than normal individuals. [152] NAWM is the place where lesions appear and the process seems to be made by microglia, in absence of leukocyte infiltration, astrogliosis or demyelination.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
A new study has developed a treatment that can help regenerate myelin with the potential to stop and even heal the damage caused by MS. Multiple sclerosis (MS) is an autoimmune disorder in which ...
Doctors debate whether MS is an autoimmune disorder, arguing that it could possibly be a neurodegenerative disorder instead. Scientists have also made headway into several cause-related theories.
A repair process, called remyelination, takes place in early phases of the disease, but the oligodendrocytes are unable to completely rebuild the cell's myelin sheath. Repeated attacks lead to successively less effective remyelinations, until a scar-like plaque is built up around the damaged axons.
Multiple sclerosis (MS) is an autoimmune disease resulting in damage to the insulating covers of nerve cells in the brain and spinal cord. [3] As a demyelinating disease , MS disrupts the nervous system's ability to transmit signals , resulting in a range of signs and symptoms , including physical, mental , and sometimes psychiatric problems.
In the PNS, myelin protein zero (MPZ or P0) has a similar role to that of PLP in the CNS in that it is involved in holding together the multiple concentric layers of glial cell membrane that constitute the myelin sheath. The primary lipid of myelin is a glycolipid called galactocerebroside. The intertwining hydrocarbon chains of sphingomyelin ...
