Thank you for the mention @Andy and @Amw66. I do know that Derya Unutmaz was supposed to be looking more into Bile acids. He is usually responsive and so i will try to find out whether he thinks that Bile acids metabolism deserves more attention given their importance to TRegs and TH17. I fear however that the observed disruption of TRegs and TH17 is very likely to be non-ME specific. I feel that we need to check whether TH17/Tregs findings differentiate ME patients from other patients with autoimmune disorders (e.g colitis, psoriasis, RA) : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5877591/
