Anti-invasive effects of Celastrus Orbiculatus extract on interleukin-1 beta and tumour necrosis factor-alpha combination-stimulated fibroblast-like synoviocytes

摘要

BackgroundInvasion of fibroblast-like synoviocytes (FLSs) is critical in the pathogenesis of rheumatoid arthritis (RA). The metalloproteinases (MMPs) and activator of nuclear factor-kappa B (NF-κB) pathway play a critical role in RA-FLS invasion induced by interleukin-1 beta (IL-1β) and tumour necrosis factor-alpha (TNF-α). The present study aimed to explore the anti-invasive activity and mechanism of Celastrus orbiculatus extract (COE) on IL-1β and TNF-α combination-stimulated human RA-FLSs.
