| Outline of Final Research Achievements |
It is an urgent task to reduce physical disorder caused by low back pain, reduce health inequality and extend healthy life span. Inflammation associated with disc degeneration and sensory nerve invasion are reported as one cause of low back pain. In this study, as a novel mechanism of inflammation induction, PAR-1 agonist stimulation was assumed and PAR-1 receptor expression in mouse intervertebral disc was shown. In addition, it proved that the migration ability of mouse macrophages is actually enhanced by cytokines released by this stimulation.
These results lead to clarification of disc degenerative processes and activation of inflammation. Furthermore, we aim to become a new treatment for low back pain by blocking this molecule.
