Allergy shots can be helpful for reducing the signs and symptoms of seasonal allergies (to grass or tree pollen for example). What is the proposed mechanism for how allergy shots work?
A. The injections contain epinephrine, which prevents release of histamine from mast cells.
B. The injections contain an inhibitor of B class switching that prevents secretion of IgE.
C. Delivery of small doses of allergens stimulates IgG production, which competitively inhibits IgE.
D. The injections contain an inhibitor of mast cell maturation. E. Delivery of immunoglobulins against the allergens shields them from IgE recognition.
The proposed mechanism for allergy shots is to inhibit the excess production of IgE antibodies against particular allergen when given periodically at specific doses and stimulate the IgG antibody production where IgG protects the body from bacteria and viruses.
The correct answer is C.
