Is there a way to turn an autoimmune disease around, back to a normal response?
The exciting answer is, yes. At least in animal experiments so far. In many cases there is an excess of activity in the Th1 T cell population, which produces inflammation; by slightly modifying the antigen, the response can be coaxed over to Th2, and inflammation goes away. Keep your eye on this for breakthroughs in human treatment.
