Outline of Final Research Achievements |
Human alfa1-acid glycoprotein (AGP) is known as an acute phase reactant, and we have recently found anti-inflammatory effects of AGP. In this study, the effect of AGP on renal protection on adriamycin-nephropathy (AN) mice was investigated. As a result, administration of AGP to AN mice reduced proteinuria and improved kidney tissue inury. At that time, the expression level of TNF-alfa and macrophage marker F4/80 in the kidney was decreased. Addition of AGP to macrophages resulted in an increase in IL-10 production and a decrease in iNOS expression. At the same time, gene expression of CD 163 also increased. In conclusion, we discovered for the first time that AGP exerts a renoprotective effect through the calming of the inflammatory response caused by macrophages.
