    Mayo Clinic researchers have linked the T cell disfunction seen in rheumatoid arthritis with a metabolic deficiency, according to a new publication in Nature Immunology. In "helper" T cells donated by Mayo Clinic patients, low levels of a specific amino acid lead to cellular miscommunication, and supplying it may provide a new therapeutic strategy for autoimmune disease.
