Outline of Research at the Start

今回、慢性アレルギー炎症の観点から1型AIPの病態解明を行うとともに、各種免疫細胞のTGF-betaシグナルがどのようになっているのかを検討し線維化の機序を明らかにすることを目的とする。このように1型AIPを含むIgG4関連疾患において、系統立てた自然免疫反応の役割と線維化についての研究はなく、この研究成果は病態解明に大きく寄与するものと予想される。

Outline of Final Research Achievements

We previously reported the role of M2 macrophage and basophil in type 1 autoimmune pancreatitis. Moreover, neutrophil which is characteristic in type 2 AIP, play an important roll in type 1 AIP. Recently, invariant T cells such as Mucosal-associated invariant T cell(MAIT cell)、invariant natural killer T cell(iNKT cell)、γδT cell is receiving a lot of attention in pathophysiology in several diseases.
Then we examined peripheral MAIT cell, iNKT cell and γδT cell in the patients wit type 1 AIP.
There is no significant difference among healthy control group, chronic pancreatitis group and type 1 AIP groups.

Academic Significance and Societal Importance of the Research Achievements

近年、自然免疫反応が様々な疾患に関与されていることが報告されており、本研究はその中でも近年注目されているMAIT細胞、iNKT細胞、γδT細胞について検討したことは、1型AIPの病態解明には重要な役割を果たしたと考える。
