Background Nowadays, the vast majority of research focusing on cough in sensitive and/or hyperreactive airways is done on an animal model of guinea pigs intraperitoneally sensitized by ovalbumin. There are no objections to model animal – the neurophysiology and neuropharmacology of their n. X are closest to humans. However, the choice of ovalbumin as model antigen together with the route of administration remains questionable – allergy to chicken eggs in humans manifests as food allergy, not respiratory allergy. These limitations may represent possible obstacles in translation of results in daily clinical practice. Therefore there is need to develop and validate new model of airway hypersensitivity, which would simulate real-life conditions more closely and new model could improve translation of results. Most important indoor allergen for people are house dust mites (HDM), most common species being D. pteronyssius and D. farinae. Their allergenic potential is complex – it includes immunogenic epitopes, faecal pellets, lipopolysaccharides, betaglucans and chitin.
