Jane’s symptoms are the result of her brain coming under attack from her own immune system. Her immune cells, whose job is to protect her body against microbial invaders, have instead set their sights on a fatty substance called myelin, which wraps around her nerve fibres. Gradually they are tearing apart this myelin insulation, leaving her neurons unable to carry electrical signals efficiently. The reason for the attacks is still a mystery.
I find it amazing that we continue to see this kind of comment from some researchers after 70 years of MS research has yet to prove this theory. And you have other docs like Dr. Barrett who have examined the brains of MS patients who have died from very severe attacks and found no evidence at all from the involvement of the person's immune system.
Then I saw that Tysabri was being used in the investigative trials!! What some researchers do to try and prove that by shaking up a MS patient's immune system, the answer will be found.
