Explanation:
Detailed explanation-1: -Atopy-Atopy is the genetic predilection to produce specific IgE following exposure to allergens. At a cellular level, atopy appears to result, in part, from a predisposition toward a certain response on the part of CD4+ T helper cells called a T helper type 2 (Th2) response [1].
Detailed explanation-2: -IgE plays a central role in the pathogenesis of atopic disorders. The binding of IgE to the Fc epsilon RI receptor on the surface of mast cells induces an immediate hypersensitivity reaction in allergic rhinitis, atopic dermatitis, asthma, food allergies, and anaphylaxis.
Detailed explanation-3: -Allergens are small antigens that commonly provoke an IgE antibody response.
