| Outline of Final Research Achievements |
The hygiene hypothesis is a hypothesis that states a lack of early childhood exposure to infectious agents increases susceptibility to allergic diseases by suppressing the development of Th1-based immunity. In this study, we investigated whether respiratory syncytial virus (RSV) infection in infancy affects allergic responses in adult mice. As a result, mice that infected with RSV at a week old significantly increased susceptibility to house dust mite-induced allergic responses at 8 weeks old. These results suggest that RSV infection in infancy leads to enhanced susceptibility to allergic diseases.
