T cells have a symbiotic relationship with vitamin D. Not only does the T cell extend a vitamin D receptor, in essence asking to bind to the steroid hormone version of vitamin D, calcitriol, but the T cell expresses the gene CYP27B1, which is the gene responsible for converting the pre hormone version of vitamin D, calcidiol into the steroid hormone version, calcitriol.
