Background
Network pharmacology explores the protective mechanism of Sophoraflavescens on atopic dermatitis (AD).
Methods
With the help of the Traditional Chinese Medicine System Pharmacology Technology Platform (TCMSP) and the Swiss target prediction database, the effective ingredients and potential target information of the active ingredients of Sophoraflavescens were obtained, and the human gene database (GeneCards) software was used to screen out the target genes related to atopic dermatitis. Using network pharmacology to explore possible molecular mechanisms.
Results
A total of 38 active ingredients and 508 corresponding targets of Sophoraflavescens were screened out, of which the core target is PAR-2. Sophoraflavescens and cetirizine can significantly improve the degree of inflammatory cell infiltration in AD model mice, reduce pruritus symptoms and pathological damage, and reduce the levels of PGE2, CGRP, LTB4 and SP. Inhibit the expression of PAR-2 and the downstream receptor TrK-A protein.
Conclusions
Sophoraflavescens and its components can affect AD pruritus by inhibiting the PAR-2 signaling pathway.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
