| Summary: | Cow’s milk is one of the most important and basic nutrients introduced early in life in our diet but can induce IgE-associated allergy. IgE-associated allergy to cow’s milk can cause severe allergic manifestations in the gut, skin and even in the respiratory tract and may lead to life-threatening anaphylactic shock due to the stability of certain cow’s milk allergens. Here, we provide an overview about the allergen molecules in cow’s milk and the advantages of the molecular diagnosis of IgE sensitization to cow’s milk by serology. In addition, we review current strategies for prevention and treatment of cow’s milk allergy and discuss how they could be improved in the future by innovative molecular approaches that are based on defined recombinant allergens, recombinant hypoallergenic allergen derivatives and synthetic peptides.
