Myelin is the protective insulation surrounding nerve fibers of the central nervous system (the brain and spinal cord).
MS symptoms result when inflammation and breakdown affect myelin.
Scientists believe that overcoming this blockage and allowing the body to function as designed (remyelinate) is more straightforward than trying to induce an entirely foreign process or mechanism.

 The Myelin Project: June 2004 Progress Report
Although these cells do not normally make myelin, they are able to do so when transplanted to areas of demyelination in the brain or spinal cord, as shown by Dr. Franklin’s previous work in rats.
As you know, The Myelin Project is based on a spirit of private initiative—most of our funds are contributed from families struck by one myelin disease or another.
Ian Duncan of the University of Wisconsin-Madison and his research associate Dr. Abdelmadjid Belkadi report further progress in their experiment involving transplantation of oligodendrocyte progenitor cells (OPCs) into the myelin-deficient (md) rat, a strain that is born without myelin, and serves as a model for both PMD and some aspects of MS.

 A Look at Myelin and Myelin-Related Disorders
The characteristics and specific functions of myelin have not fully been explored by researchers, and as far as I can tell most current research efforts are initiated by groups that research myelin-related disorders, such as the Myelin Profect.
As we have seen, the production, make-up and functions of myelin are very complex, and they are interrupted in very specific ways in myelin-related disorders, some of which were described here.
These different ways of affecting the myelin lead to different symptoms in the patient, which explains the multitude of demyelinating disorders that have so far been identified These different disorders often have very fine distinctions.

It seems likely from animal models of multiple sclerosis (experimental autoimmune encephalomyelitis) that initial relapsing-remitting phases of the disease centre on one antigen component, perhaps of myelin basic protein, but that, as the disease progresses, antigens from other proteins become involved.
Myelin occurs in both the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) but the cells that produce the myelin differ.

Myelin basic protein (MBP) MEDLINE:1710177, MEDLINE:1710279 is a hydrophilic protein that may function to maintain the correct structure of myelin, interacting with the lipids in the myelin membrane by electrostatic and hydrophobic interactions.
In mammals various forms of MBP exist which are produced by the alternative splicing of a single gene; these forms differ by the presence or the absence of short (10 to 20 residues) peptides in various internal locations in the sequence.

Demyelination is the term used for a loss of myelin, a substance in the white matter that insulates nerve endings.
Myelin helps the nerves receive and interpret messages from the brain at maximum speed.
When nerve endings lose this substance they can not function properly, leading to patches of scarring, or ‘sclerosis’, occurring where nerve endings have lost myelin.
