Question

Allergens are

• A. Infectious and increased secretion of IgE
• B. Non- infectious and increased secretions of IgE
• C. Infectious and increased secretion of IgG
• D. Non- infectious and increased secretion of IgM

Answer 1

The correct option is B Non- infectious and increased secretions of IgE

An allergen is a usually harmless substance capable of triggering a response that starts in the immune system and results in an allergic reaction.

IgE is an immunoglobulin that plays a central role in acute allergic reactions and chronic inflammatory allergic diseases.

Human allergy is caused by a limited number of inhaled small-protein allergens that reproducibly elicit IgE production in susceptible individuals.

So the answer is option B ' Non- infectious and increased secretions of IgE'.
