Abstract

Atopic dermatitis (AD) is a recurrent and chronic inflammatory skin condition characterized by a high lifetime prevalence and significant impairment of patients' quality of life, primarily due to intense itching and discomfort. However, current pharmacological interventions provide only moderate efficacy and are frequently accompanied by adverse side effects. The immune-pathogenesis of AD involves dysregulation of the Th2 immune response and exacerbation of inflammation related to excessive Reactive Oxygen Species (ROS). Therefore, to address these issues, in this study, we targeted the upstream pathogenesis by designing a pro-Th1 Adjuvant nanoemulsion loaded with poly(I:C) and encapsulated with the ROS-scavenger vitamin E, termed PV-NE. PV-NE effectively rebalanced the Th1/Th2 immune response and reduced ROS levels both in vivo and ex vivo, leading to the restoration of immune balance in AD-affected skin and alleviation of symptoms such as lichenification and erythematous patches. In conclusion, our development of the reductive Adjuvant nanosystem PV-NE demonstrates its biocompatibility and efficacy in combating AD progression without the use of immunosuppressant glucocorticoids. This has the potential to significantly impact the design and enhancement of pharmacotherapy in future clinical research aimed at curing AD.
