Abstract

The present study examined the efficacy of the topical 15d‑PGJ2‑poloxamer 407 hydrogel in an atopic dermatitis (AD) animal model. The 15d‑PGJ2 hydrogel was prepared and characterized. The examined rats possessed AD‑Like cutaneous lesions, which were induced using 2,4‑dinitrochlorobenzene, the rats were then treated with a hydrogel vehicle, 15d‑PGJ2 hydrogel or tacrolimus for 14 days. The rats were sacrificed and blood samples were collected to quantify the IgE levels. Subsequently, skin biopsies were stained with toluidine blue to identify mast cells and immunohistochemistry was performed for ROR‑γt and TNF‑α. Histological analyses demonstrated that 15d‑PGJ2 hydrogel significantly decreased mast cell infiltration (P<0.05) when compared with the AD‑group. Tacrolimus at 0.1% exhibited decreased mast cell infiltration; however, this difference was not statistically significant from the AD‑group. Topical 15d‑PGJ2 hydrogel and Tacrolimus 0.1% significantly reduced the serum levels of IgE (P<0.05) compared with the AD‑group. Immunohistochemistry revealed a significant decrease in ROR‑γt and TNF‑α positive cell expression (P<0.05) in the 15d‑PGJ2 hydrogel group compared with the AD‑group. In summary, topical administration of 15d‑PGJ2 hydrogel had a beneficial effect on AD symptoms, suggesting that this formulation may be a useful strategy for the treatment of AD.
