Dermatophagoides farinae allergen (multiple group allergens) (Der f (followed by group number, e.g., Der f 1, Der f 2, Der f 7, Der f 23))

Dermatophagoides farinae allergens are a family of proteins produced by the American house dust mite that trigger allergic responses in sensitized individuals. Multiple allergen groups have been identified and characterized structurally, including Der f 2 (which has a hydrophobic lipid-binding cavity)[1], Der f 7 (which binds bacterial lipopeptides)[2], and Der f 23 (which contains chitin-binding domains)[3]. These allergens interact with IgE antibodies in allergic patients, causing immune responses that manifest as asthma, rhinitis, eczema, and conjunctivitis[9]. Rather than being therapeutic targets themselves, Der f allergens are relevant to allergy diagnosis and potential immunotherapy development. The specific IgE binding profiles vary among allergen groups and between dust mite species, offering opportunities for more targeted allergy testing and treatment strategies. Note: This is not a single therapeutic target. "Dermatophagoides farinae allergen" requires specification of which allergen group (Der f 1, Der f 2, Der f 7, Der f 23, etc.) is being referenced for meaningful therapeutic target classification.
