My hero, the pioneering neuroimmunologist Dr. Michal Schwartz, has written a terrific new book. It is for laypeople, and explains the misconception of the brain's immune system and how her research has over-turned 100 years of wrong thinking about immune cells and the brain. Neuroimmunity: A New Science That Will Revolutionize How We Keep Our Brains Healthy and Young. Before taking any serious immune ablating drugs to treat MS, please read her take on the subject. She has been proven right. http://ccsviinms.blogspot.com/2015/06/dr-michal-schwartz-was-right.html
