Outline of Final Research Achievements |
The purpose of this study was to elucidate the mechanism of food allergy remission. As a means to achieve this, we aimed to establish a novel transdermal immunotherapy by administering nanoparticles transdermally. However, mice in the control group without nanoparticles also showed spontaneous remission (outgrowth) on multiple occasions. We decided that it was necessary to investigate the cause of the outgrowth in order to provide transdermal immunotherapy, so we focused on clarifying the mechanism of the outgrowth. We conducted a cross-sectional study in humans as a possible mechanism of the outgrowth and published our findings on the possibility that antigen-specific IgD is involved (Itoh N. Allergy. 2021).

Academic Significance and Societal Importance of the Research Achievements |
本研究成果は、未だ解明できていない食物アレルギーの耐性獲得の機序解明に繋がる可能性を秘めている。現在検討している抗原特異的IgDは、その意義自体が近年まであまり明らかではなく、今後明らかにされることで食物アレルギーに限らず、アレルギー疾患全般に貢献する可能性がある。 社会的にも、現在アレルギー疾患は2人に1人は持つと言われており、その影響は大きい。本研究課題である食物アレルギーも、誤食によるアナフィラキシーが生命の危機を招いたり、社会的に問題となるいじめに発展することも報告されており、その食物アレルギーの治療の発展が社会的にも大きな意義を持つ。
