Research Abstract

The understanding of the steroid-resistant mechanism of the T-cell level to characterize severe asthma is important as a premise of the treatment intervention. For the purpose of performing a preclinical study, we established a steroid-resistant asthmatic model. Steroid sensitivity evaluation was done using the steroid sensitivity of the in vitro T-cell clone and T-cell clone transfer mice asthma model (in vivo). By the administration of dexamethasone (Dex), lymphocyte count and eosinophil count in BALF of mice transfected with steroid-sensitive clone, was reduced in a dose-dependent manner. On the other hand, there was no significant reduction in the case where it is transferred with steroid-resistant clones. Namely, it was able to confirm that steroid sensitivity and resistance in the culture system (in vitro) accorded with the sensitivity in the asthma model (in vivo).
