Whether or not XMRV turns out it is good to have data on an immune signature in CFS patients. If XMRV holds up it will probably be a significant advance for the field. It is too bad that we don't have data on CFS vs XMRV with CFS vs controls...Unfortunately I can't find the immune signature info Peterson believes the immune signature is the key.... It is good to see the WPI getting published, I agree. I think they have one more paper coming out.
