Is It an Auto Immune?

In the thirties, there were lab mice going, hey, it's auto immune, right? And doctors were like, oh, don't listen to the lab results from those silly mice. They sort of were not looking at the evidence right nd front of their faces for a little while. In 19 forty seven, they found that these weird protein by products, and they're in their cerebra spinal fluid. So when they find all this stuff, they can say, this is probably multiple sclerosis.
