Outline of Final Research Achievements

Allergic dermatitis (AD), associated with pruritus and itchiness, is one of the major stressful conditions early in life. AD also influences the incidence of neuropsychiatric disorders and developmental disorders through neuro-immune interactions. To the best of our knowledge, there is no report that assesses the effects of early childhood dermatitis on psychiatric disorders later in life using an animal model.
Here, we developed an oxazolone (Ox)-induced AD model in the early life and found that we suggest that early life stress from AD aggravates susceptibility to systemic inflammation in the adolescent brain, leading to depressive behaviors with abnormal kynurenine metabolism.

Academic Significance and Societal Importance of the Research Achievements

これまで乳幼児期のアトピー性皮膚炎に対する予防や治療として皮膚症状や随伴するアレルギー症状に焦点をあてた予防・治療計画が主流でありましたが、今後は将来の精神・神経発達を含めた予防や治療の重要性を示すことが出来ました。また、乳幼児期のストレス全般においてその後の精神・神経発達への影響に脳内炎症に対するプライミング機構の関与が明らかとなってきています。本研究では乳幼児期の環境が将来の精神・神経発達へ及ぼす影響に対する分子機構の一部を明らかにすることが出来、今後新たな予防法や治療法開発につながることが期待されます。
