| Outline of Final Research Achievements |
Lumbar intervertebral disc (IVD) degeneration is attributable mainly to LBP, called discogenic pain, which often leads to disc herniation presenting as sciatica. We investigated the effects of inhibition of c-Fos/AP-1（T-5224）on IVD degeneration and associated pain. We used a tail disc percutaneous needle puncture method to further assess the effects of oral administration of T-5224 on IVD degeneration. Analysis of x-ray, MRI findings, and histology revealed that IVD degeneration was significantly mitigated by T-5224. Further, oral administration of T-5224 ameliorated pain as indicated by the extended tail-flick latency in response to heat stimulation of rats with needle-puncture-induced IVD degeneration. T-5224 prevented disc degeneration, and oral administration of T-5224 extended the tail flick latency as a measure of heat stimulation in the rat tail-puncture model. These findings suggest that the inhibition of c-Fos/AP-1 prevents disc degeneration and its associated pain.

| Academic Significance and Societal Importance of the Research Achievements |
腰椎椎間板変性は、脊柱管狭窄症、ヘルニア、腰痛の原因の一つである。これらの疾患は若年-中高年まで労働生産性の高い年代に患うことが多い。現在臨床応用可能な椎間板変性抑制の薬はなく、早期臨床応用可能な治療法の開発は急務である。椎間変性が抑制できれば、多くの腰痛や狭窄症に悩む患者にとって非常に朗報である。c-fos/AP-1阻害薬（T-5224）は、動物実験レベルでは椎間板変性抑制作用とその関連痛を抑制した。この薬は実際にヒトへの投与も可能であり、実際に臨床的効果が得られれば、労働生産性の向上など社会的利益も大きい点で、極めて有益な研究であると確信する。
