Research Abstract

IL-6 Amp is important for autoimmune diseases and chronic inflammation. In order to identify the target molecules of IL-6 Amp, several genome-wide screening methods were carried out. As results, an inflammatory chemokine Ccl20 that enhances the recruitment of a subset of T cells is identified as a key target. With those findings," a four-step model" for organ-specific autoimmune diseases was presented. Finally, a soluble molecule highly presented in the patients with an autoimmune disease was found to be important for regulating IL-6 Amp, that opens new possibilities for the drug development.
