Not wanting to put a dampener on things as it is UCL, so very reputable as was said, however there was talk on another thread over on the XMRV forum of it being connected to patients of Simon Wessley or Peter White (can't remember which one now, someone can clarify I am sure) so therefore is likely to be enrolling patients who are fitting the looser description of CFS/ME and will therefore be unlikely to find as much XMRV as perhaps if they took a few of us off here. It's research nonetheless though so we'll see what it brings eh.
