1, 25 Dihydroxyvitamin D3 modulated cytokine response in pulmonary tuberculosis

, 2007
1, 25 Dihydroxyvitamin D3 (1, 25(OH)2 D3) has gained significant importance in tuberculosis with regard to its immunoregulatory activities. Our aim was to evaluate the effect of 1, 25(OH)2 D3 on cytokine response to Mycobacterium tuberculosis antigens ...

Human bone cells in culture metabolize 25-hydroxyvitamin D3 to 1,25-dihydroxyvitamin D3 and 24,25-dihydroxyvitamin D3

, 1981
Bone cells respond to 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) for mineral mobilization and contain receptors for 1,25(OH)2D3. We report here the expression of 25-hydroxyvitamin D3 (25 (OH)D3) metabolizing enzymes in primary cultures of human bone cells ...

Vitamin D3 and Monomethyl Fumarate Enhance Natural Killer Cell Lysis of Dendritic Cells and Ameliorate the Clinical Score in Mice Suffering from Experimental Autoimmune Encephalomyelitis

Toxins, 2015
Experimental autoimmune encephalomyelitis (EAE) is a CD4+ T cell mediated inflammatory demyelinating disease that is induced in mice by administration of peptides derived from myelin proteins. We developed EAE in SJL mice by administration of PLP139–151

Rapid Actions of 1 -25-Dihydroxyvitamin D3 Physiologic Role

Experimental Biology and Medicine, 1994
The steroid hormone, 1 alpha,25-dihydroxyvitamin D3 (1 alpha,25-[OH]2D3), has been shown to exert actions on cells within seconds. The rapidity of these effects has led to the speculation that they reflect nongenomic actions of the hormone which involve interaction with membrane receptors. Moreover, these rapid effects appear to modulate the actions of

Toll-Like Receptor Signaling in Bovine Macrophages Increases 1,25-Dihydroxyvitamin D3 Production [PDF]

, 2008
Recognition of pathogen associated molecular patterns by Toll-like receptors (TLR) increases 1α-hydroxylase expression in bovine macrophages. This results in increased conversion of 25-hydroxyvitamin D3 (25(OH)D3) to 1,25- dihydroxyvitamin D3 (1,25(OH)

The serum vitamin D status in adults with diabetic retinopathy: A systematic review and meta-analysis [PDF]

Journal of Medical Biochemistry
Background: Emerging evidence suggests that vitamin D may play a crucial role in the development of diabetic retinopathy (DR). However, the extent of vitamin D deficiency in individuals with DR remains uncertain.
