Background

Vitamin D aids in the absorption of calcium and has central roles in bone formation and maintenance, hypertension, cancer, and immunity.^1,2 In addition, the active form of vitamin D, 1,25-dihydroxy vitamin D₃, decreases the proliferation and increases differentiation of keratinocytes.³ 1,24-dihydroxy Vitamin D₃ is an analog of 1,25-dihydroxy vitamin D₃ which, when used in a 4 μg/g ointment, safely and effectively suppresses psoriasis.⁴ It also is effective at increasing the time interval between phototherapy cycles when ultraviolet light is used for psoriasis.⁵ 1,24-dihydroxy Vitamin D₃ inhibits the growth of both normal and psoriatic human keratinocytes (IC₅₀ ~ 10 nM) via the vitamin D receptor.⁶ It also suppresses the production of RANTES and IL-8 by human dermal fibroblasts and reduces cutaneous lymphocyte-associated antigen on CD4⁺ T cells, impairing migration and skin infiltration.^7,8
