A paper in the June 2011 issue of the journal Infection and Immunity offers evidence vitamin D can boost your immune system.
(PHYSORG)- Laboratory-grown gingival cells treated with vitamin D boosted their production of an endogenous antibiotic, and killed more bacteria than untreated cells, according to a paper in the June 2011 issue of the journal Infection and Immunity. The research suggests that vitamin D can help protect the gums from bacterial infections that lead to gingivitis and periodontitis. Periodontitis affects up to 50 percent of the US population, is a major cause of tooth loss, and can also contribute to heart disease. Most Americans are deficient in vitamin D.
His interest piqued by another laboratory’s discovery that vitamin D could stimulate white blood cells to produce natural proteins that have antibiotic activity, Gill Diamond of the UMDNJ—New Jersey Dental School, Newark, showed that vitamin D could stimulate lung cells to produce LL-37, a natural antibiotic protein, and kill more bacteria. That suggested that , vitamin D might help cystic fibrosis patients. Next, in the new research, he showed that vitamin D has the same effct on gingival cells.
Then, Diamond found that vitamin D also stimulates gingival cells to produce another protein, called TREM-1, which had not been well-studied, but which was thought to be made by white blood cells. He found that it boosts production of pro-inflammatory cytokines.
