| Outline of Final Research Achievements |
A recent report has revealed a gene polymorphism that is associated with reduced risk of Alzheimer's disease within the IL-33 gene region in addition to decreased IL-33 expression in the brains of patients with Alzheimer's disease. Furthermore, IL-33 has been reported to reduce the expression of beta-amyloid (Abeta40). Thus, it has been suggested that IL-33 may act as inhibitors against the development of Alzheimer's disease. However, the precise mechanism of reduced IL-33 expression and the physiological role for cognitive function of IL-33 in the brain remains unclear. In this study, we investigated the physiological role of IL-33 in cognitive function using IL-33 deficient mice. As a result, we revealed that IL-33 and its intracellular signaling factor is involved in learning and memory formation.
