Jackson Labs ME/CFS Collaborative Center Director Derya Unutmaz and his collaborator and microbiome expert Julia Oh recently published a study in the journal Mucosal Immunology, titled “Tuning of human MAIT cell activation by commensal bacteria species and MR1-dependent T-cell presentation.” Mucosal-associated invariant T (MAIT) cells are a type of T cell present in various sites of the body, including the gut mucosa, and defend against microbial infection by recognizing a particular bacterial metabolite shown to them by antigen presenting cells (APCs). In the gut microbiota, there are many different species of bacteria present and yet, MAIT cells don’t mount an immune response to all of them. It is therefore likely that these cells can distinguish which types of bacteria are beneficial to us and which are harmful. The findings from this study could be highly relevant for ME/CFS patients, who are thought to have disruptions of both their immune system and their microbiome.
