The Complex V study is a good one. That's for EBV.All the ME metabolomics and mitochondrial research to date hasn’t found anything abnormal with the functioning of our mitochondria except for this paper I believe:
An Isolated Complex V Inefficiency and Dysregulated Mitochondrial Function in Immortalized Lymphocytes from ME/CFS Patients
Prusty and Naviaux have shown HHV-6 causes mito dysfunction as well.
EBV and HHV-6 are two of the most (if not THE two most) viruses associated w/ ME/CFS.
I don't understand why people still question whether mitochondrial dysfunction plays a role in CFS..
