1 Intralesional Injection of Vitamin D in Verruca Vulgaris Increases Cathelicidin (LL37) Expression; Therapeutic and Immunohistochemical Study. Vitamin D cathelicidin antimicrobial peptide Homo sapiens
2 Introduction: Despite the promising results of intralesional vitamin D in verruca treatment; its precise mechanism of action is not fully understood.Aim of the work: To investigate immunohistochemical expression of cathelicidin (LL 37) before and after injection of vitamin D in verruca vulgaris and to clarify its possible role in pathogenesis of verruca.Patients and methods: This study included 20 patients with multiple verrucae vulgaris. Vitamin D cathelicidin antimicrobial peptide Homo sapiens
3 Significant increase in LL37 intensity of expression was observed after intralesional injection of vitamin D3 (p = 0.003) and in verrucae showing complete clinical response (p = 0.022).Conclusions: Intralesional injection of vitamin D is effective and safe treatment for verruca vulgaris and causes increase in LL37 expression. Vitamin D cathelicidin antimicrobial peptide Homo sapiens
