Solution

Question number 1 :

Answer : IgE is the antibody responsible for allergic rhinitis. This is commonly known as hay fever. Other IgE mediated disorders includes asthma, atopic dermatitis (eczema) and food allergies.

Supplementary Information : Allergic Rhinitis The most common atopic disorder results from the reaction of airborne allergens with sensitized mast cells in the conjunctivae and nasal mucosa to induce the release of pharmacologically active mediators from mast cells; these mediators then cause localized vasodilation and increased capillary permeability. The symptoms include watery exudation of the conjunctivae, nasal mucosa, and upper respiratory tract, as well as sneezing and coughing.
