Vitamin D and the anti-viral state.
Vitamin D has long been recognized as essential to the skeletal system. Newer evidence suggests that it also plays a major role regulating the immune system, perhaps including immune responses to viral infection. Interventional and observational epidemiological studies provide evidence that vitamin D deficiency may confer increased risk of influenza and respiratory tract infection. Vitamin D de...
متن کاملThe anti-cancer actions of vitamin D.
Vitamin D3 is biologically inert. To become active, it requires two successive hydroxylation steps catalyzed by two cytochrome P450 enzymes, first to synthesize the pro-hormone 25-hydroxyvitamin D3 [25(OH)D3] and then the active hormone 1α,25- dihydroxyvitamin D3 [1α,25(OH)2D3]. 1α,25(OH)2D3 has high affinity for the vitamin D receptor (VDR), a transcription factor and a member of the steroid r...

متن کاملVitamin D and The Magic Mountain: the anti-infectious role of the vitamin.
V itamin D status has become a ‘‘hot topic’’ in human nutrition. In part, the concept of osseous and non-osseous effects of the active form of the vitamin underlies this expanded emphasis on vitamin D nutrition. There are 2 mechanisms by which human beings acquire vitamin D: ingestion from the diet and synthesis after exposure to sunlight. The discovery that appreciable segments of human popula...
متن کاملVitamin D deficiency and stroke
Vitamin D comprises a group of fat-soluble pro-hormones, obtained from sun exposure, food, and supplements, and it must undergo two hydroxylation reactions to be activated in the body. Several studies have shown the role of vitamin D in mineral metabolism regulation, especially calcium, phosphorus, and bone metabolism. Some factors such as inadequate vitamin intake and liver or kidney disorders...
