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

The vitamin D radio is a nuclear receptor that is activated by the vitamin D hormone. This can be a receptor that varieties a heterodimer with the retinoid X receptor. The capturing of the calciferol complex with all the RXR ends in the account activation of many intracellular signaling pathways. These types of pathways encourage immediate answers independent of the transcriptional response of target genes.

VDRs can also be thought to mediate the effects of vitamin D on cuboid maintenance. This is supported by the relationship between bone density and VDR radio alleles in human beings. In addition , numerous VDR goal genes are generally identified, including calcium-binding protein, calbindin D-9k and 25-hydroxyvitamin D3 24-hydroxylase.

Many studies include investigated the expression of VDR in various flesh. For instance, confocal microscopy has revealed VDR elemental staining in human cortex cells. In addition , VDR has been diagnosed in white matter oligodendrocytes. These studies have triggered the speculation that calcium-dependent platelet service may be regulated by quick non-genomic effects of VDR in mitochondria.

In addition to vitamin D, VDRs have been implicated in dangerous calcium homeostasis in the intestinal tract. Nevertheless , the exact system is not known. Various factors, including environmental exposures and genetic elements, may control VDR phrase.
