Molecular biology of the calciferol receptor (VDR) is a key factor in most processes which can be important for general homeostasis. VDRs tend to be found in a variety of skin cells, including monocytes, dendritic cellular material, macrophages, neutrophils, keratinocytes, and epithelial cells.

The vitamin D receptor is a elemental receptor that is activated by the vitamin D hormone. This can be a receptor that varieties a heterodimer with the retinoid X radio. The capturing of the vitamin D complex when using the RXR brings into reality the account activation of many intracellular signaling pathways. These types of pathways stimulate immediate responses independent of the transcriptional response of target family genes.

VDRs are likewise thought to mediate the effects of vitamin D on bone tissue maintenance. This is maintained the relationship between cuboid density and VDR receptor alleles in humans. In addition , a number of VDR target genes have been completely identified, which includes calcium-binding proteins, calbindin D-9k and 25-hydroxyvitamin D3 24-hydroxylase.

Many studies contain investigated the word of VDR in various tissues. For instance, confocal microscopy has shown VDR nuclear staining in human cortex cells. In addition , VDR has been diagnosed in white matter oligodendrocytes. These results have triggered the hypothesis that calcium-dependent platelet activation may be governed by quick non-genomic effects of VDR in mitochondria.

In addition to vitamin D, VDRs have been implicated in dangerous calcium homeostasis in the digestive tract. Nevertheless , the exact device is not as yet known. Various elements, including environmental exposures and genetic factors, may regulate VDR manifestation.
