Research Abstract

The results of this study show that intervertebral disc (IVD) cells express PAR-2. The expression of PAR-2 is regulated by IL-1β stimulation. PAR-2 activation accelerates the expression of matrix degrading enzymes. PAR-2 may play an important role in the cytokine-mediated catabolic cascade and consequently may be involved in IVD degeneration.
