Question

Which of the following is a cause of allergy which is stored in mast cells?

• A. Interferons
• B. Histamine
• C. Immunoglobulins
• D. None of the above

Answer 1

The correct option is B Histamine

Allergies are the reactions or the response given to the antigens which are in the form of particles. Allergy is also termed as hypersensitivity. The cells release IgE antibodies, histamines and other cytokines which manifest the symptoms of the reaction. When the allergen is encountered, the mast cells and basophils undergo degranulation which releases histamine. Histamine is the inflammatory agent.

Thus, the correct answer is option B.
