House Dust Mite Allergen-Specific Immune Response (HDM Immune Response)

The house dust mite (HDM) allergen-specific immune response is a complex immunological process triggered by exposure to proteins from house dust mites. It involves both innate and adaptive immunity, with a strong bias toward Th2-type responses that promote IgE production and eosinophilic inflammation. This response is a major driver of allergic diseases such as asthma, allergic rhinitis, and atopic dermatitis. Key features include epithelial barrier disruption, activation of innate immune cells via pattern recognition receptors, Th2 polarization, allergen-specific IgE production, and mast cell/basophil degranulation upon re-exposure.
