There seems to be a certain co-morbidity between ME and Irritable Bowel Syndrome (IBS). This article has found a mechanism. One can imagine similar mechanisms causing the general inflammation in other tissues, known by many ME-sufferers.

From the press release:
We were able to demonstrate that the level of the Bcl-3 protein, which also plays a role in the development of various cancerous diseases, is elevated in the intestinal tract of colitis patients and is indeed a trigger of the disease," said Dr. Hövelmeyer, head of the work group at the Mainz-based Institute for Molecular Medicine. According to the study, Bcl-3 impacts intestinal health through interaction with the regulatory T cells (Tregs) whose main task is to prevent overreaction of the immune system.
"We were able to demonstrate that Bcl-3 suppresses the activation of Tregs by preventing the necessary genes from being read," explained Dr. Glasmacher, head of the team at the Institute for Diabetes and Obesity in Munich. "Bcl-3 interacts with the transcription factor p50, which is otherwise responsible for activation, and blocks it."
"Consequentially, the regulatory T cells remain passive, the immune system is no longer regulated, and inflammatory processes begin to take place. Experiments using various models have revealed that elevated quantities of Bcl-3 cause certain cells to migrate to the intestines, where they trigger a severe inflammatory response," Sonja Reissig, Ph.D., lead author of the paper and research associate at Mainz University Medical Center, pointed out.
"The results represent a major contribution toward our understanding of chronic intestinal inflammation and hopefully over the long term will help us discover aspects that we can target with new therapies," concluded Dr. Hövelmeyer.
