Type I Hypersensitivities
Multiple Choice
Which statement about the mechanism & desired outcome of desensitization immunotherapy is correct?
A
It will increase the number of IgE antibodies, saturating the receptors on mast cells/basophils which prevents them from degranulating.
B
It shifts the immune response toward allergen-specific IgG antibodies, which intercept antigens before they can bind to IgE antibodies on mast cells/basophils.
C
It promotes IgG antibody production to intensify the response of wheal-flare reactions, improving their diagnostic accuracy.
D
It reduces the number of all antibodies, thereby weakening the allergic reaction.
