Аннотация
BACKGROUND: Sjögren's syndrome (SS) is a complicated autoimmune disorder, encompassing multifaceted pathogenesis of inflammatory response, immune dysregulation and metabolic abnormalities. Shaoteng Decoction (STD) is a type of traditional Chinese medicine preparation that has been shown to effectively improve inflammatory damage and immune dysfunction in patients with SS. Nevertheless, the exact mechanism has not been unspecified.
PURPOSE: This work aims to determine the mechanism of STD treatment on SS, identifying potential therapeutic targets and their relationships.
METHODS: Non-obese diabetic mice served as a disease model. This study analyzes potential signaling pathways of STD treatment for SS through network pharmacology, and assesses the role of STD in reducing inflammatory damage using pathological staining, ELISA, and immunohistochemistry. Additionally, the study apply gut microbiota, metabolomics, and proteomics analyses to identify the key microbiota, metabolites and proteins, aiming to find potential action targets of STD. We use Western blotting and immunohistochemistry to verify the authenticity of the relevant targets and study the interactions among gut microbiota, metabolites, and proteins.
RESULTS: Proteobacteria is the important intestinal bacteria, Bile Acid Biosynthesis is the main metabolic pathway, IfI30, Ndufv3, and Ndufs6 are the crucial differential expressed proteins. Moreover, there is a strong correlation among the three. STD treats SS by reducing the abundance of Proteobacteria, increasing Bile Acid Biosynthesis, decreasing IfI30 expression, and increasing the expression of Ndufv3 and Ndufs6.
CONCLUSION: STD inhibits inflammatory responses, improves immune dysregulation and energy metabolism abnormalities, and prevents the progression of SS through regulating the gut microbiota, enhancing Bile Acid Biosynthesis, and modulating proteins expression levels.
