Researchers measured levels of a immune signaling molecule called TGF-β1 in blood cells from ME/CFS patients and compared them to healthy people and patients with other illnesses. They found that ME/CFS patients had significantly higher levels of TGF-β1 than both groups, suggesting this molecule may play a role in ME/CFS disease development.
