In vitiligo perilesional skin, IFN-γ levels were significantly decreased in the skin of 5 μg/kg 1,25(OH)2D3-treated mice (p = 0.0019), which was more pronounced than that in the skin of mice treated with 1 μg/kg 1,25(OH)2D3 (p = 0.0193, Figure 6d). This evidence concerns the gene IFNG and vitiligo.
