Learning Objectives for "The Adaptive Immune System: Type I Immediate Hypersensitivity"

After completing this section you should be able to perform the following objectives.

1. Describe the mechanism for Type I (IgE-mediated) hypersensitivity and give 3 examples. State how they are treated symptomatically.

2. Describe how desensitization (allergy) shots work to lessen the severity of Type I hypersensitivities.

3. Briefly describe how monoclonal antibodies against the Fc portion of IgE may someday be used to prevent Type I allergies.

4. When a person has hay fever, common symptoms include runny eyes, runny nose, swollen sinuses, and difficulty in breathing. In terms of humoral immunity, discuss the mechanism behind these symptoms. Also state the reason for giving antihistamines.
