The active form of vitamin D, 1,25-dihydroxyvitamin D(3)[1,25(OH)(2)D(3)], is a secosteroid hormone that regulates calcium and bone metabolism, controls cell proliferation and differentiation, and exerts immunoregulatory activities. This range of functions has been exploited clinically to treat a variety of conditions, from secondary hyperparathyroidism to osteoporosis, to autoimmune diseases such as psoriasis. Recent advances in understanding 1,25(OH)(2)D(3) functions and novel insights into the mechanisms of its immunomodulatory properties suggest a wider applicability of this hormone in the treatment of autoimmune diseases and allograft rejection.
