[Current Topics on Vitamin D. The vitamin D functions in keratinocytes and its therapeutic applications].
1,25 (OH) 2D and calcium have been shown to promote epidermal keratinocyte differentiation and prevent proliferation. These prodifferentiation and antiproliferative effects of 1,25 (OH) 2D have led to its clinical use in the treatment of psoriasis. However, the mechanism of vitamin D action on keratinocytes remains largely unknown. While the actions of calcium and the vitamin D receptor signaling pathways on epidermal keratinocyte differentiation are redundant, their effects on the hair follicle are not. In this review, we discuss how the vitamin D and its receptor contribute to skin and hair follicle homeostasis.
