Mouse models of allergic diseases.

The increasing prevalence of allergic diseases worldwide is posing significant socio-economic challenges. The pathogenesis of these diseases reflects a complex interaction of genetic and environmental factors. The heterogeneity of disease phenotypes challenges the concept of single mechanisms of disease. As human experimentation is limited, animal models have been developed to provide insights into pathogenesis and potential for discovery of novel therapeutics. Mice have served in models of many of the allergic diseases including asthma, allergic rhinitis, food allergy, atopic dermatitis (AD), and allergic conjunctivitis. Although much has been learned from these investigations, there are limitations when these models are translated to the human diseases.
