What role does the immune system play with ms?

Very complicated. Latest info suggests an inborn genetic susceptibility with environmental triggering events. The basic pathology causes the immune system to mistake brain and spinal cord myelin as a foreign entity. Data regarding grey matter involvement is starting to explain much of what is occurring. All current meds target lymphocyte trafficking, (t cells), but the b cell research is exciting.
Pivotal role. This is a complex and not fully understood aspect of ms. Certain immune cell population recognize proteins in the insulation coating surround nerve fibers in the central nervous system as "foreign". This results in a cascade of events leading to injury of the insulation material and underlying nerve fiber. Other factors possibly separate from immune attack also play a role in ms.
Autoimmune disease. Ms is an autoimmune disease, so the antibodies in your system are working adversely against the neurologic system in your body. Much of the treatment is aimed at down-regulating this aberrant immune reaction.

I see in MS & gbs the immune system only seems to attack the mylein sheath. What stops the immune system going further & directly attacking the nerves?

Read on . Nerves are affected too early axonal degeneration is well known in ms the antibody is specific even in examples given, in ms the antibody is against oligodendrocytes forming the myelin in the central nervous system and in guillain barre is against the schwan cells forming the myelin in the peripheral nervous system!

Specific antibodies. ...Only against myelin are the hallmark of ms and guillain-barre (also transverse myelitis.) other types of autoimmune neurologic disease target other parts of the nervous system: myasthenia gravis, sydenham's chorea, and post-varicella cerebellitis are all examples.

Neuropathy. Although much is known about the mechanisms involved in multiple sclerosis, the cause remains unknown. Theories include genetics or infections. Guillain-barre sydrome involves autoimmune responses but has multiple inciting factors, and the reasons why autoimmune responses are to schwann cells is not understood. Good questions. If you could answer - nobel prize? Read more...
Variable. Yes, in many cases, the myelin sheath alone is involved, and the underlying axon is spared, BUT immune systems are variable, and the more aggressive forms of MS and GBS can result in axonal damage. It is the body's ability to turn off the immune attack which quells the ultimate damage. Read more...

Can myelin injection treat MS, since the immune system is attacking myelin sheeth adding myelin in blood will keep WBC away from the nerves, right?

Wrong. This simply doesn't work. It's simplistic and in fact, you're asking for making the body more sensitive. Your body also makes attacking white cells to order when confortonted with something that it's sensitized to. Tolerization procedures exists for some autoimmune diseases and the whole are is fascinating. Read more...
Practicalities. First, do you or anyone close to you have MS? Secondly, where did you read about myelin injections, as this is scientifically inappropriate and unsound, and has NO conceivable role in legitimate treatment of a rather bad disease? Lots of opinions regarding MS on the internet, so, be very skeptical. Read more...
