Immune System Imbalance in ME

In researching ME, I kept coming across references to scientific findings of an imbalance between th1 and th2.  I didn't know what that was about, but I had bookmarked it in my mind as something to research in the future.  In the meantime, another ME/CFS blogger, Sue Jackson, wrote a post today that I think clearly summarizes the issue in lay terms.  So I'm going to link to her post.  It is a quick, easy read.
