Regulatory T cells (Tregs) are anti-inflammatory. They produce the anti-inflammatory cytokines TGF-β and IL-10. They suppress effector Th1, Th2, and Th17.

Dietary and environmental factors[edit | edit source]

Vitamin D improves regulatory T cell function in healthy adults[1] and in patients with relapsing remitting multiple sclerosis (MS),[2] suggesting that it may play a role in both preventing and ameliorating autoimmune disease.

Various species of probiotics have been shown to increase FoxP3 expression in animal models.[3]

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).[4] The same group found elevated Tregs in a multiple sclerosis comparison study.[5]

However, a study that used the Revised Canadian Consensus Criteria (2010) criteria found Tregs were depleted in 76 people with ME/CFS.[6]

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.[7]

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.[8]
