| Outline of Final Research Achievements |
In most pollen allergy patients, symptoms worsen overnight or early in the morning. Although the circadian pathophysiology of pollen allergy is well documented, the biological basis of this phenomenon remain poorly unknown. In this study, "circadian clocks" were directly verifies that involved in the pathogenesis of pollen allergy using allergic rhinitis model. The severity of allergic rhinitis symptoms in wild-type mice showed a time-of-day-dependent variation, whereas, was absent in clock mutant mice. Furthermore, a time-of-day-dependent variation in the severity of allergic rhinitis symptoms observed in wild-type mice was absent by administering a drug that effects on the circadian clocks. A time-of-day-dependent variation in the severity of allergic rhinitis symptoms in the healthy mice was absent in the mouse chronic jet lag model.
These results suggested that "circadian clocks" is involved in pathogenesis of pollen allergy.
