Abstract

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.

期刊介绍： Phytomedicine is a therapy-oriented journal that publishes innovative studies on the efficacy, safety, quality, and mechanisms of action of specified plant extracts, phytopharmaceuticals, and their isolated constituents. This includes clinical, pharmacological, pharmacokinetic, and toxicological studies of herbal medicinal products, preparations, and purified compounds with defined and consistent quality, ensuring reproducible pharmacological activity. Founded in 1994, Phytomedicine aims to focus and stimulate research in this field and establish internationally accepted scientific standards for pharmacological studies, proof of clinical efficacy, and safety of phytomedicines.
