Regulatory T cell

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

Dietary and environmental factors
Vitamin D improves regulatory T cell function in healthy adults and in patients with relapsing remitting multiple sclerosis, suggesting that it may play a role in both preventing and ameliorating autoimmune disease.

Various species of probiotics have been shown to increased FoxP3 expression in animal models.

Chronic Fatigue Syndrome
Tregs are elevated in CFS.
