Question

Inflammatory response in an allergy is caused by the release of

• A. Antigen
• B. Histones
• C. Histamines
• D. Antibodies

Answer 1

The correct option is C Histamines

Histamine is an organic nitrogenous compound involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter. Histamine is involved in the inflammatory response. As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues.

Thus, the correct answer is option C.
