| Outline of Final Research Achievements |
The molecular mechanism of developing low back pain is known as disc degeneration by MMP and following nerve innervation by NGF, however that of neck pain was unknown. The effect of selective COX-2 inhibitors, which is clinically used for both low back pain and neck pain, on NGF and MMP expressions were investigated and compared the effect between human lumbar and cervical intervertebral disc (IVD) cells. IL-1-induced NGF and MMP expression were enhanced by selective COX-2 inhibitors in both lumbar and cervical IVD cells, on the other hand, these expressions were suppressed by PGE2 and other prostanoids via EP4 receptor. Our findings would be of importance when choosing drugs for the treatment of low back pain and neck pain.
