My boss sent this to me from a Canadian website: http://www.canada.com/Health/story.html?id=1539611
The article is discussing a treatment for progressive MS, rather than relapsing-remitting. The experimental treatment discussed is a stem-cell transplant to reboot the immune system. This is not a simple or easy procedure, so it is a last effort type treatment. The patients in the trial have not had any relapses or new brain lesions. While it may not be a cure, it is very promising for the worst MS cases prior to disability.
Interestingly, they reported that the cost of treatment, although expensive, would pay for itself in about three years due to the cost of MS drugs.
