| Outline of Final Research Achievements |
Patients with type 1 diabetes are currently increasing, and environmental factors are thought to be one of its causes. Asian sand dust (ASD) is the suspended particulate matter. The events of ASD flying to Japan are increasing since 2000. Although ASD is designated as one of reference materials for air quality to protect public health, it is still unclear whether ASD can become the environmental factor of diabetes onset. In this study, we examined the effect of ASD on type 1 diabetes by using two systems of type 1 diabetes model mice with different pathogenesis. As a result, it was suggested that ASD may become either the exacerbating factor or suppressor for the diabetes onset depending on the system of the type 1 diabetes model mice. However, it is unknown what kind of mechanisms cause such conflicting results. Therefore, further examinations are required.
