Abstract
Objective: Rheumatoid arthritis (RA) is a chronic inflammatory disorder. Pyridostigmine (PYR), an acetylcholinesterase (AChE) inhibitor, has been shown to reduce inflammation and oxidative stress in several animal models for inflammation-associated conditions. The present study aimed to investigate the effects of PYR on pristane-induced (PIA) in Dark Agouti (DA) rats.
Method: DA rats were intradermally infused with pristane to establish the PIA model, which was treated with PYR (10 mg/kg/day) for 27 days. The effects of PYR on synovial inflammation, oxidative stress, and gut microbiota were evaluated by determining arthritis scores, H&E staining, quantitative polymerase chain reaction, and biochemical assays, as well as 16S rDNA sequencing.
Results: Pristane induced arthritis, with swollen paws and body weight loss, increased arthritis scores, synovium hyperplasia, and bone or cartilage erosion. The expression of pro-inflammatory cytokines in synovium was higher in the PIA group than in the control group. PIA rats also displayed elevated levels of malondialdehyde, nitric oxide, superoxide dismutase, and catalase in plasma. Moreover, sequencing results showed that the richness, diversity, and composition of the gut microbiota dramatically changed in PIA rats. PYR abolished pristane-induced inflammation and oxidative stress, and corrected the gut microbiota dysbiosis.
Conclusion: The results of this study support the protective role of PYR in PIA in DA rats, associated with the attenuation of inflammation and correction of gut microbiota dysbiosis. These findings open new perspectives for pharmacological interventions in animal models of RA.
期刊介绍:
Scandinavian Journal of Rheumatology is the official journal of the Scandinavian Society for Rheumatology, a non-profit organization following the statutes of the Scandinavian Society for Rheumatology/Scandinavian Research Foundation. The main objective of the Foundation is to support research and promote information and knowledge about rheumatology and related fields. The annual surplus by running the Journal is awarded to young, talented, researchers within the field of rheumatology.pasting
The Scandinavian Journal of Rheumatology is an international scientific journal covering clinical and experimental aspects of rheumatic diseases. The journal provides essential reading for rheumatologists as well as general practitioners, orthopaedic surgeons, radiologists, pharmacologists, pathologists and other health professionals with an interest in patients with rheumatic diseases.
The journal publishes original articles as well as reviews, editorials, letters and supplements within the various fields of clinical and experimental rheumatology, including;
Epidemiology
Aetiology and pathogenesis
Treatment and prophylaxis
Laboratory aspects including genetics, biochemistry, immunology, immunopathology, microbiology, histopathology, pathophysiology and pharmacology
Radiological aspects including X-ray, ultrasonography, CT, MRI and other forms of imaging.
