How the gut microbiome supports iron uptake by intestinal regulatory T-cells
Research paper discusses the relationship between iron deficiencies and immune tolerance in patients with inflammatory bowel disease. The study shows that high cellular iron levels fostered by pentanoate, a short-chain fatty acid produced by intestinal microbiota, are necessary for the homeostasis of regulatory T cells in the intestine, and iron deficiencies in Treg can result in lethal autoimmune disease.
