摘要：Osteoarthritis (OA) is a degenerative joint disease associated with inflammation. Polygonatum sibiricum polysaccharide (PSP) is a major group of active components isolated from Polygonatum sibiricum with broad activities including anti-inflammatory effect. However, the role of PSP in OA is unclear. In the present study, we aimed to investigate the effects of PSP on IL-1β-induced inflammatory response in primary human OA chondrocytes. The results showed that PSP improved cell viability of chondrocytes in response to IL-1β induction. The increased levels of several inflammatory mediators including nitric oxide (NO), prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in IL-1β-induced chondrocytes were attenuated by PSP in a dose-dependent manner. The IL-1β-induced production of pro-inflammatory cytokines, TNF-α and IL-6, were mitigated by PSP in chondrocytes. Besides, PSP also suppressed the production of matrix metalloproteinases (MMPs), including MMP-1, MMP-3 and MMP-13 in IL-1β-stimulated chondrocytes. Furthermore, the IL-1β-induced activation of NF-κB signaling pathway in chondrocytes was also prevented by PSP. These findings suggested that PSP alleviated IL-1β-induced inflammatory response in chondrocytes via inhibiting NF-κB signaling pathway.
