Murine models provide a powerful tool in the investigation of latex allergy and the development of intervention strategies. The immune responses to protein allergens of mice and humans are similar but differences related to the roles of IgE and IgG must be recognized. Mice have been shown to mount a dose and time-dependent IgE response to latex proteins following topical, respiratory, and subcutaneous exposures. Methods are available to evaluate cutaneous and respiratory responses to latex challenge in sensitized animals. These models have been used to investigate the role of route of exposure on the development of latex allergy and to provide a means for investigating the contribution of individual proteins to adverse respiratory and dermal responses. These models provide a mechanism for the evaluation of new technologies aimed at reducing the allergenicity of latex products, and for testing for the potential for cross-reactivity to new allergens in previously sensitized individuals. Murine models may also provide a method for testing immunotherapy strategies prior to initiating human trials.
