Outline of Research at the Start

急性腎障害は患者の生命予後に大きく影響する病態であるが、いまだに治療法が確立していない。治療につながる病態の解明が重要である。近年臨床的に重要な場面が増えてきているがん治療と腎障害の両者にまたがる概念としてOnconephrologyという領域が注目されている。その中で、免疫反応と腎障害が改めて着目され、中でも過剰な細胞性免疫が急性腎障害進展に果たす役割が重要とされている。我々が以前より検討を行っている内因性リガンドMRP8が細胞性免疫による腎障害進展に果たす役割を明かにすることは、新しい治療にヒントを与えることができると思われる。

Outline of Final Research Achievements

In this study, we investigated the role of MRP8 in the progression of acute kidney injury, expecting that administration of a vaccine against MRP8 would improve the condition, but the results were the opposite of what we expected. Therefore, we created and analyzed a different model in which the effect of humoral immune activation was more likely to be expected. We performed a right renal IRI to induce MRP8 expression-induced preconditioning, followed by a left renal IRI one week later for analysis. Right kidney IRI preconditioning led to suppression of inflammation and tubular injury markers in the left kidney IRI, and attenuation of the suppressive effect was observed in bone marrow-specific MRP8KO mice.

Academic Significance and Societal Importance of the Research Achievements

ワクチンそして対側腎IRIプレコンディショニングによる検討により、急性期の抗MRP8ワクチンは病態を悪化させた一方、プレコンディショニングがIRIによる腎障害軽減効果の少なくとも一部は内因性MRP8先行暴露が重要である可能性が可能性が示唆された。ワクチン実験の結果はAKI急性期にはMRP8が病態悪化に寄与することを示す既報の一機序として、急性期のMRP8に対する細胞性免疫賦活化が示唆される。反対にMRP8先行暴露のプレコンは保護的な可能性があるため、開心術など事前にAKI発症が予測されるような場面における臨床介入に繋がることが期待される。
