 Located in the nucleus of a variety of cells including immune cells, the VDR is a control system of sorts. When exposed to infection and damage, especially that which is caused by pathogens, the body begins to convert the inactive form 25-D into the active form, 1,25-D. As cellular concentrations of 1,25-D increase, 1,25-D activates the VDR, turning on any number of genes the receptor transcribes.  Located in the nucleus of a variety of cells including immune cells, the VDR is a control system of sorts.

 According to a 2010 analysis, the VDR significantly affects 229 human genes. Many of these genes have long been associated with autoimmune diseases and cancers including, for example, the genes IRF8 (linked to multiple sclerosis), and PTPN2 (connected to Crohn's disease and type I diabetes).(({{pubmed>long:20736230}})) The activation of certain genes also leads to the synthesis of antimicrobial peptides. The antimicrobial peptides are the body's "natural antibiotics" and have a potent anti-bacterial effect. According to a 2010 analysis, the VDR significantly affects 229 human genes.
