Remyelination is the process of propagating oligodendrocyte precursor cells to form oligodendrocytes to create new myelin sheaths on demyelinated axons in the Central nervous system (CNS). This is a process naturally regulated in the body and tends to be very efficient in a healthy CNS. [ 1 ]
The process and mechanistic function of myelinogenesis has traditionally been studied using ultrastructure and biochemical techniques in rat optic nerves. The implementation of this method of study has long allowed for experimental observation of myelinogenesis in a model organism nerve that consists entirely of unmyelinated axons. Furthermore ...
The process of generating myelin is called myelination or myelinogenesis. In the CNS, oligodendrocyte progenitor cells (OPCs) differentiate into mature oligodendrocytes, which form myelin. In humans, myelination begins early in the 3rd trimester, [ 11 ] although only little myelin is present in either the CNS or the PNS at the time of birth.
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.
Nervous system injuries affect over 90,000 people every year. [2] Spinal cord injuries alone affect an estimated 10,000 people each year. [ 3 ] As a result of this high incidence of neurological injuries, nerve regeneration and repair, a subfield of neural tissue engineering , is becoming a rapidly growing field dedicated to the discovery of ...
Why the meat you eat affects your brain. The connection between red meat and cognitive health hasn’t been studied thoroughly, but researchers have found associations with many other health ...
Repair processes, called remyelination, also play an important role in MS. Remyelination is one of the reasons why, especially in early phases of the disease, symptoms tend to decrease or disappear temporarily. Nevertheless, nerve damage and irreversible loss of neurons occur early in MS.
Neither Suboxone nor methadone is a miracle cure. They buy addicts time to fix their lives, seek out counseling and allow their brains to heal. Doctors recommend tapering off the medication only with the greatest of caution. The process can take years given that addiction is a chronic disease and effective therapy can be a long, grueling affair.
