Outline of Final Research Achievements

The production of pro-inflammatory cytokines was found to be far larger at the co-culture group that was cultured with macrophages and Fas Ligand (FasL) overexpressed intervertebral nucleus pulposus cells. Furthermore, it was found that the expression of ADAM (A Disintegrin And Metalloproteinase) 10, which controls the expression of FasL, was also increased. And also, mRNA expression of TNF-α was significantly increased stimulating by IL-1β+adiponectin.
From these results, we consider that FasL and ADAM10 play an important role in the production of pro-inflammatory cytokines coming from interaction of the intervertebral nucleus pulposus cells and macrophages. Also, the adiponectin which is an adipocyte specific hormone known to have anti-diabetic, anti-atherogenic and anti-inflammatory effects, may have inhibited permanently inflammatory reaction around the intervertebral disc.
