Abstract

Abstract: Cockroach allergy is associated with the development of asthma. The identification of cockroach allergens, which began in the 1990 s, is an ongoing process that has led to the current listing of 20 official allergen groups in the WHO/IUIS Allergen Nomenclature database. The function and structure of some of these allergens has been determined and define their natural delivery into the environment and their allergenicity. Analysis of antigenic determinants by X-ray crystallography and rational design of site-directed mutagenesis led to the identification of IgE binding sites for the design of molecules with reduced IgE reactivity and T cell modulatory capacity. New developments in recent years include component analyses of B and T cell reactivity and a recent cockroach immunotherapy trial, CRITICAL, that will contribute to understand the immune response to cockroach and to define future directions for cockroach allergy diagnosis and immunotherapy. Highlights: Cockroach (CR) allergy is associated with the development of asthma. CR extracts for diagnosis and immunotherapy (IT) show high molecular heterogeneity. Subjects have unique B and T cell reactivity profiles (no immunodominant allergens). Crystallographic analyses of CR allergens contribute to design molecules for IT. CR IT trial CRITICAL and new experimental approaches will inform future therapies.
