let me see if I understand something about this report- I don't

consider myself any kind of genius. And I definitely don't know what

some of those words mean but, I'm wondering....

are they trying to say that the immune system is part of rebuilding

the myelin? So that by supressing the immune system may be supressing

the rebuilding of myelin?

Am I getting this right??
