Article: Are B-Cells to Blame for ME/CFS?

Building on my last post (the article about methotrexate), Discovery Magazine's new May, 2013, issue includes an article highlighting research which suggests that defective B cells may be responsible for ME/CFS.  This theory has been receiving considerable press lately.  It's hard not to get a little excited by the hub-bub, but at the same time, one hopes that all the excitement is because there's really something to this theory and that it's not just another XMRV-like disappointment.
