Allergological implication of the quaternary hexameric structure of the cockroach allergen Per a 3

Abstract

Our data indicate that the quaternary structure can influence both allergenicity and immunogenicity, also depending on the sensitization status. The monomeric variant of Per a 3 allergens could be a possible candidate for a specific immunotherapy because the IgE-mediated allergic reaction and the Th2-inducing capacity are diminished while the Th1-inducing capacity is retained.
