Does Vitamin D affect immune system response?

In a recent Science Daily article they report on an experiment published in the June 2011 edition of Infection and Immunity.


The experiment covered in the article showed that laboratory-grown gingival cells treated with vitamin D boosted their production of an endogenous antibiotic, and killed more bacteria than untreated cells.


The article suggests this means vitamin D can protect gums from bacterial infections that lead to gingivitis and periodontitis.


In addition to the antibiotic mentioned above, the researchers found that the cells treated with Vitamin D produce another protein, called TREM-1. While this protein has not as yet been well-studied, it is thought to be made by white blood cells and boosts production of pro-inflammatory cytokines.


While as yet unresearched this may be the means by which Vitamin D protects against autoimmune diseases.
