Question

Quizplus · Accepted Answer

During allergic desensitization, the goal is to shift the immune response from a Th2-mediated response to a Th1-mediated response. The Th1 response leads to the production of IgG antibodies which can block the allergen from binding to IgE on mast cells and basophils, preventing the release of inflammatory mediators that lead to symptoms of an allergic reaction. Therefore, IgG is the immunoglobulin that blocks the allergen from binding with IgE in the theory for allergic desensitization.
