Induction of allergic rhinitis in mice

Abstract

We describe a method for allergic rhinitis (AR) induction in mice. Methodology involves nasal infusions of small volumes of ovalbumin for both initial sensitization and challenges. The latter are frequent and carried out over several weeks. This methodology more closely resembles natural AR induction than does the common use of systemic sensitization, often with adjuvants, followed by nasal challenges with relatively large allergen volumes. Also described are methodologies for collection of cardiac blood and perfusion for preparation of histological samples, both essential in verifying AR induction in individual animals. © 2013 Springer Science+Business Media, LLC.
