Abstract:

BACKGROUND: Atopic individuals predispose to allergic rhinitis after contacting with an allergen, which is mainly released by IgE-mediated histamine. Allergic rhinitis is a kind of non-infectious inflammatory disease that involves a variety of immune cells and cytokines and is related to Th1 and Th2 immune imbalance. Interferon γ is a cytokine secreted by Th1 cells, while interleukin-4 is a cytokine secreted by Th2 cells.

OBJECTIVE: To establish a stable 129Sv mouse model of allergic rhinitis, so as to lay the foundation of establishing gene knockout 129Sv mouse models of allergic rhinitis, and to observe the concentration variation of IgE, interleukin-4 and interferon γ.

METHODS: Twenty-four mice were randomly divided into 2 groups: model and control groups. Mice in the model group were sensitized by intraperitoneal injection of ovalbumin to establish mouse models of allergic rhinitis. Mice in the control group were subjected to intraperitoneal injection of PBS. After successful modeling, pathological changes of nasal eosinophils and plasmocyte infiltration were evaluated by nasal mucosa staining. Interleukin 4 and interferon γ levels and ovalbumin-specific IgE antibody concentration were detected by enzyme-linked immunosorbent assay.

RESULTS AND CONCLUSION: Enzyme-linked immunosorbent assay showed that compared with the control group, serum ovalbumin-IgE and interleukin-4 concentrations were significantly increased, and  Interferon γ concentration was significantly lower in the model group (P < 0.05). Hematoxylin-eosin staining results showed that cilia lodging and submucosal serous gland hyperplasia, eosinophils and plasmocyte infiltration were obvious. These results confirm that a mouse model of allergic rhinitis was successfully constructed in this study and the pathogenesis of allergic rhinitis was related to Th1/Th2 imbalance.
