Vitamin D can have a huge effect on the immune system and people may be more susceptible to diseases such as complex sclerosis, scientists have been found.
The body generates vitamin D in response to sunlight and scientists investigated how it affects the immune system – the ability of dendritic cells to activate T cells.
In healthy people, T cells have a very important role in helping to treat a disease, but in people with self-belief conditions, they can start to attack the body's own meat.
By examining cells from both mice and humans, researchers found that vitamin D was caused by more dendritic cells of the molecules called CD31, and that this restricted the functioning of cells T.
CD31 was seen to be hindering both types of cells from making sustainable contact – an integral part of the operational process – and the movement of security was very low.
Professor Richard Mellanby, of the University of Edinburgh's Center for Research on Regeneration, said: "Low levels of D vitamin have been a long-standing feeling as a significant and threatening feature to develop many self-inflicting diseases. T .
"Our study shows one way in which metabolites of vitamin D can have a huge impact on the immune system."
The study, published in the Borders of the Migration, was funded by the Medical Council Research Council, the Biotechnology and Biological Sciences Council, the Natural Environment Research Council and the Wellcome Council.
