Question

Allergens are noninfectious .They induce disorders through secretion

• A. IgM
• B. IgE
• C. Histamines
• D. Both B and c

Answer 1

The correct option is D Both B and c

An allergen is a type of antigen which are non-infectious that produces an abnormally vigorous immune response in which the immune system fights off a perceived threat that would otherwise be harmless to the body. Such reactions are called allergies. The production of allergens stimulates the release of IgE (immunoglobulin E) antibodies. These IgE antibodies bind to the allergens and then activates receptors of mast cells which triggers the release of inflammatory chemicals such as histamine. Hence, allergens induce disorders through secretion of IgE and histamine.

So, the correct answer is 'Both B and C'.
