, Question 5
local symptoms of type 1 hypersensitivty
Correct Answer
itching and rash
Question 6
Type 1 hypersensitivtity immune components include
Correct Answer
•Ige antibodies, mast cells, basophils
Question 7
•Mechanism of type 1 hypersensitivity
Correct Answer
initiated by allergen exposure
Question 8
Tx of Type 1 Hypersensitivity
Correct Answer
•Avoidance of allergen
•Antihistamines
•Corticosteroids
•Epinephrine
•Desensitization immunotherapy
Question 9
type 1 hypersensitvity
Correct Answer
Fast and furious (e.g., anaphylaxis, asthma). You'll see swelling, wheezing, hives, and possibly low BP. Think EpiPen and
airway.
Question 10
Process of type 1 hypersensitivity?
Correct Answer
•First exposure: allergen stimulates B-cells to produce IgE
•IgE binds to FceRI receptors on mast cells/basophils (sensitization)
•Re-exposure: cross-linking of IgE which causes mast cell degranulation
•Release of histamine, prostaglandins, leukotrienes that leads to inflammation
