Wikipedia is no longer in doubt that MS is autoimmune. The wording has been changed to: "In MS, the body's own immune system attacks and damages the myelin. When myelin is lost, the axons can no longer effectively conduct signals."
Their reference is this 2002 Lancet study by Compston and Coles: http://bit.ly/91EFmx
Ok, I'll play - the Lancet Abstract says:
"As with all complex traits, the disorder results from an interplay between as yet unidentified environmental factors and susceptibility genes."
I understand you're just reporting this, but it's outrageous how folks (like the wikifolks) reach and get to publish some of the trash they put out. I still can't get over the one about the mouse that was cured of MS............
