This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This article reviews the role and clinical applications of 1,25-dihydroxyvitamin D3 and parathyroid hormone-related peptide in dermatology, with a focus on psoriasis treatment, and reports no new experimental findings.
