Description
House dust mite/HDM atopy patch test/APT elicits positive reactions in the majority of atopic dermatitis/AD and healthy individuals. Experimental systems for new-onset/chronic AD are needed to support rapid therapeutic development, particularly since animal models representing AD pathology in humans are lacking. HDM APT historically simulated AD, but its suitability to model the emerging AD skin phenotype as Th2/Th22 polarized with Th1 and Th17 components is unknown. To assess whether HDM APT tissues reproduce acute or chronic AD, positive HDM APT (n=14) were compared with nonlesional, acute (<72hrs; n=10), and chronic phase AD biopsies (n=8), allergic contact reactions (to nickel [n=10] and fragrance [n=3]) using arrays.
