| Research Abstract |
Life time occurrence of low back pain goes up to 60-80%, and the most common complaint at outpatient clinic in Japan is LBP. The major cause of LBP is disc degeneration, that is acted by various kinds of cytokines and enzymes. The purpose of the current study is to explain the cause of the disc degenerations, moreover to examine the possibility of new cytokine treatment. The following below are our new findings conducted by the current study in the inflammation of herniated disc. (1) TWEAK, that is the TNF-α family, must induce MMP-3 and MCP-1 through C-Jun or NF-κβ signal pathway respectively. (2) TSLP must induce MCP-1 through NF-κβ signal pathway, resulting in Mφ infiltration. (3) TNF-α must induce VEGF with TNF-α receptor I, resulting in neovascuralization. However this phenomenon is decreased by aging. (4) The induction of MMP-3 and MCP-1 induced by TNF-α and TWEAK. However this induction is decreased by aging. I would like to continue investigation of this precise mechanism, moreover to achieve the establishment of new cytokine treatment in the future.
