| Outline of Final Research Achievements |
Activation of synoviocytes that construct synovial tissue is a major pathological condition. Although glucosamine is usefull as a component of articular cartilage for regeneration of the cartilage, but it is unknown whether glucosamine affects the activation of synoviocytes.
I examined the effect of glucosamine on stretch-dependent activation of synoviocytes using a cell stretch-loading system. The pretreatment of synoviocytes with glucosamine suppressed stretch-dependent Cox-2 expression, which is a typical hallmark of synoviocytes activation. In addition, glucosamine strongly suppressed an inflammatory reagent-dependent Cox-2 expression. These results suggest that glucosamine has an ability to inhibit the synoviocyte activation.
