Principles and Application of Mouse Model of Allergic Rhinitis / 대한이비인후과학회지

ABSTRACT

Allergic rhinitis is a one of the most prevalent disease and its prevalence has been increasing these days. Many researchers have used the mouse models to study the mechanism of allergic rhinitis and development of anti-allergic medications. In the fields of allergic disease, several models such as allergic asthma, allergic contact dermatitis, and allergic rhinitis etc are introduced and several modifications are used. In case of mouse models of allergic rhinitis, it has been developed and modified from allergic asthma model. Most commonly used allergic rhinitis models are acute models and chronic models are used less. Ovalbumin, house dust mite and fungus are most commonly used allergens. Usually, mouse are sensitized with allergen and adjuvant such as aluminum hydroxide gel or Freund adjuvant for 2-3 weeks (once/week) then are challenged with allergen intranasally every day for 1 week. Mouse are sacrificed within 24 hours after final challenge and several parameters of allergic rhinitis are evaluated. They include nasal rubbing and sneezing count, eosinophil count in the nasal mucosa, total and allergen specific immunoglobulin E, nasal cytokine level and splenic cytokine level by splenocyte culture. By revealing those parameters, researchers could identify the allergic status of the mouse. However, there are many variables in mouse model of allergic rhinitis such as mouse strain, type of allergen, sensitization time, adjuvant, acute or chronic type, and allergen administration route etc. In this review, several variables and protocols of mouse model of AR will be discussed in detail.
