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.
Guillain–Barré syndrome – nerve damage. Neuroregeneration in the peripheral nervous system (PNS) occurs to a significant degree. [5] [6] After an injury to the axon, peripheral neurons activate a variety of signaling pathways which turn on pro-growth genes, leading to reformation of a functional growth cone and regeneration.
Fox News host Laura Ingraham says a "real president answers questions" as she reflects on President-elect Donald Trump's openness with the media on "The Ingraham Angle."
There’s a lot of information out there about how to lose weight—and some tidbits are more reliable than others. But new research suggests that tweaking your diet to feature more protein and ...

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.
