Australian research unlocks [URL="http://www.msra.org.au/unlocks-genetic-mechanism"][U]genetic mechanism behind vitamin D and its role in MS[/U][/URL]
[QUOTE]New research published in the Journal of Genes & Immunity has identified the genetic switch which shows how immune cells are controlled by vitamin D and sheds light on how vitamin D may be used as a therapy for MS.
The research group, led by Professor David Booth at the Westmead Institute for Medical Research, says it has long been known that vitamin D deficiency is associated with autoimmune diseases such as multiple sclerosis (MS), but until now researchers did not know the exact biological mechanism for this association.
'Understanding the genes that control the vitamin D response in MS and the types of immune cells that offer protection, helps us to pave the way for more targeted approaches for people with this disease,' Professor David Booth said.[/QUOTE]
[QUOTE]Professor Booth and his team discovered that three known MS risk genes, which control vitamin D activation, are “turned on” in specific cells called myeloid cells. Myeloid cells are a type of immune cell found in the skin and lymph nodes. Until now, nobody has looked at how the genes work in these cells in relation to MS and vitamin D.
With the help of a powerful technique called ChIP Seq, which analyses protein interactions with DNA, they found that the genes, including the risk genes, are controlled by vitamin D in the myeloid cells.
'We now have the key to help develop more targeted treatments to help people with this devastating disease,' Professor Booth said.[/QUOTE]
