[The vitamin D endocrine system].
The vitamin D endocrine system comprises a group of 7-dehydrocholesterol-derived secosteroid molecules, including its active metabolite 1,25-dihydroxy-vitamin D (1,25(OH)(2)D), its precursors and other metabolites, its binding protein (DBP) and nuclear receptor (VDR), as well as cytochrome P450 complex enzymes participating in activation and inactivation pathways of those molecules. The biologi...
متن کاملVitamin D endocrine system and osteoclasts
Vitamin D was discovered as an anti-rachitic agent preventing a failure in bone mineralization, but it is now established that the active form of vitamin D3 (1α,25(OH)2D3) induces bone resorption. Discovery of the receptor activator of nuclear factor -κB ligand (RANKL) uncovered the molecular mechanism by which 1α,25(OH)2D3 stimulates bone resorption. Treating osteoblastic cells with 1α,25(OH)2...
متن کاملThe immunological functions of the vitamin D endocrine system.
The discoveries that activated macrophages produce 1alpha25-dihydroxyvitamin D3 (1alpha,25-(OH)2D3), and that immune system cells express the vitamin D receptor (VDR), suggested that the vitamin D endocrine system influences immune system function. In this review, we compare and contrast how 1alpha,25-(OH)2D3 synthesis and degradation is regulated in kidney cells and activated macrophages, summ...
متن کاملThe endocrine vitamin D system in the gut.
The active vitamin D metabolite 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3) has important regulatory actions in the gut through endocrine and probably also intracrine, autocrine and paracrine mechanisms. By activating the vitamin D receptor (VDR), which is expressed at a high level in the small intestine and colon, 1,25(OH)2D3 regulates numerous genes that control gut physiology and homeostasis. 1,...
متن کامل[Vitamin D and endocrine diseases].
Vitamin D insufficiency/deficiency has been worldwide reported in all age groups in recent years. It has been considered a Public Health matter since decreased levels of vitamin D has been related to several chronic diseases, as type 2 diabetes mellitus (T2DM), obesity and hypertension. Glucose intolerance and insulin secretion has been observed during vitamin D deficiency, both in animals and ...
