Ampelopsis Brevipedunculata (Maxim.) Trautv Extract Alleviates Symptoms of Atopic Dermatitis in NC/Nga Mice

Atopic dermatitis is a common allergic skin disease characterized by eczema, dryness, and severe itching, which has a significant impact on patients’ quality of life. Its pathogenesis involves immune dysregulation and impaired skin barrier function. In this study, the therapeutic potential of Ampelopsis brevipedunculata (Maxim.) Trautv for alleviating atopic dermatitis symptoms was investigated using the NC/Nga mouse model. A. brevipedunculata (Maxim.) Trautv was effective in attenuating the atopic dermatitis-like epidermal thickening and the immune cell infiltration in the skin lesions induced by the atopic dermatitis ointment. Additionally, A. brevipedunculata (Maxim.) Trautv suppressed the production of inflammatory mediators and chemokines associated with atopic dermatitis progression. In addition, A. brevipedunculata (Maxim.) Trautv exhibited restorative effects on skin barrier dysfunction by increasing the expression of key barrier proteins. Mechanistically, A. brevipedunculata (Maxim.) Trautv modulated the mitogen-activated protein kinase pathway and inhibited nuclear factor-kappa B activation. These findings highlight the potential of A. brevipedunculata (Maxim.) Trautv as a promising therapeutic agent for treating atopic dermatitis and provide insight into its mechanisms of action.
