Regulatory T cell
Dietary and environmental factors[edit | edit source]
Vitamin D improves regulatory T cell function in healthy adults and in patients with relapsing remitting multiple sclerosis (MS), suggesting that it may play a role in both preventing and ameliorating autoimmune disease.
Chronic Fatigue Syndrome and ME/CFS[edit | edit source]
An Australian group found that Tregs were elevated in thirty individuals with Fukuda for chronic fatigue syndrome (CFS). The same group found elevated Tregs in a multiple sclerosis comparison study.
A second study in Japan also found decreased Tregs in 41 people who met both the Canadian Consensus Criteria and the International Consensus Criteria as compared to age- and gender-matched healthy controls.
It is worth noting that such seemingly contradictory results are often found in the systemic autoimmune diseases in which T cell subsets are often studied. Even in illnesses with well-established biomarkers, age, gender, and time since onset lead to significant variability.

chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
