I think we mentioned this study before. I would like to see the results repeated by another team. I was a bit puzzled by the immunofluorescent results I seem to remember. My intuition is that in ME an autoimmune response would be to something less specifically related to cardiovascular responses. I would caution against the idea that bits of evidence for something being autoimmune always 'add up'. If there is autoimmunity to one target then it is probably less likely that there autoimmunity to another target. If it was Colonel Mustard in the Library it probably wasn't Professor Plum in the Conservatory as well, if you see what I mean!
