- Abstract: BACKGROUND: VitabridC¹² is newly developed and composed of vitamin C and Vitabrid (lamellar, hydrated zinc oxide). OBJECTIVE: In this study, we aimed to investigate the effects of VitabridC¹² on psoriasis and atopic dermatitis. METHODS: Mice with imiquimod-induced psoriasis or Dermatophagoides farinae-induced atopic dermatitis were applied with VitabridC¹². The effects of VitabridC¹² were evaluated by clinical features, histology, and immunologic features by examining cytokines and chemokines. RESULTS: In psoriasis model, VitabridC¹² decreased epidermal thickness and reduced inflammatory cell infiltration. In atopic dermatitis model, VitabridC¹² decreased dermal infiltration of inflammatory cells, epidermal hyperplasia, and hyperkeratosis. VitabridC¹² reduced the expression levels of proinflammatory mediators such as interleukin (IL)-1β, IL-6, IL-8, IL-17A, IL-22, tumor necrosis factor-α, CXCL1, CCL17, and CCL20 as well as COX-2 in imiquimod-induced psoriatic skin lesions. Likewise, VitabridC¹² reduced the expression levels of IL-4, IL-5, IL-13, thymic stromal lymphopoietin, and CCL4 in D. farinae-induced skin lesions, and decreased the serum immunoglobulin E level in the atopic dermatitis mouse model. Particularly, the VitabridC¹²-treated mice showed downregulated expressions of mitogen-activated protein kinase (MAPK), including extracellular signal-regulated kinase (ERK), p38, and MAPK/ERK kinase, as well as inhibited phosphorylation of nuclear factor-κB p65. CONCLUSION: Taken together, these findings indicate that VitabridC¹² exhibits anti-inflammatory activities and is a promising candidate as a treatment option for psoriasis or atopic dermatitis.
