Tendoactive®
Resumen: Tendons have a limited capacity for self-repair due to the low density and mitotic activity of tenocytes. Pro-inflammatory cytokines such as interleukin-1ß (IL-1ß) have been identified as the main initiators of tendinopathies, stimulating inflammation, apoptosis and extracellular matrix (ECM) degradation. The aim of this study was to evaluate the potential of Tendoactive®, a newly developed proprietary nutraceutical formulation that includes mucopolysaccharides, collagen and vitamin C, in an in vitro model of tendon inflammation. The effects of Tendoactive® were studied in primary cultures of human tenocytes treated with IL-1ß for up to 72 h. Expression of collagen type I, integrin ß1, cyclo-oxygenase-2 (COX-2), caspase-3 and matrix metalloproteinase-1 (MMP-1) was monitored by western blotting. The effects of Tendoactive® on the expression, phosphorylation and nuclear translocation of protein components of the NF-κB system were studied by western blotting and immunofluorescence respectively. Treatment of tenocytes with Tendoactive® suppressed IL-1ß-induced NF-κB activation and p65 nuclear translocation. These events correlated with down-regulation of NF-κB targets including COX-2, MMP-1 and activated caspase-3. Tendoactive® also reversed the IL-1ß-induced down-regulation of collagen type I and ß1-integrin receptor expression. These results indicate that Tendoactive® has nutraceutical potential as an anti-inflammatory agent for treating tendinopathy through suppression of NF-κB mediated IL-1ß catabolic signalling pathways in tenocytes.
