Vitamin D may protect asthmatics and those suffering with cystic fibrosis from an allergic response linked to the common mold, Aspergillus fumigates, suggests a new study. This environmental mold is a very widespread fungal organism that when inhaled does not normally cause any problems to the vast majority of people. However, in asthmatics and in patients with cystic fibrosis, exposure can lead to significant allergic symptoms.
In an unrelated vitamin D study, researchers have identified vitamin D receptors (VDR) on 2776 gene positions and also found 229 genes that were activated in response to vitamin D. Vitamin D receptors are proteins that become activated by vitamin D. Activated VDR can then attach to specific sites on DNA which result in the expression of certain gene traits and/or genetic products such as enzymes. VDR binding sites were densely populated near autoimmune and cancer associated genes which may imply the importance vitamin D can play in autoimmune disease and cancer prevention.
