HYPOALLERGENIC HYBRID PROTEINS OF MAJOR GROUP 1 AND 2 MITE ALLERGENS FOR USE IN THE TREATMENT OF ALLERGIES

摘要

The present invention refers to recombinant ADN molecules coding to hybrids polypeptides of different allergens from D. pteronyssinus useful for the prevention and treatment of allergies, particularly allergies caused by mites. Specifically, the invention describes hybrid proteins composed of fragments of allergens Derp p l y Derp p 2 with hypoallergenic characteristics and maintain their immunogenic capacity, being particularly useful for the treatment of allergy. The invention also describes the production methods of these polypeptides in heterologous expression systems. Besides, the invention describes efficient purification methods of these hybrid proteins.
