Examples of hypersensitivity type 1 - ANSWER: allergic rhinitis, anaphylactic reaction
Type 1 hypersensitivity reactions are mediated by what - ANSWER: IgE
What cells are involved in hypersensitivity type 1 - ANSWER: Mast cells
symptoms of hypersensitivity type 1 - ANSWER: local: itching, immediate rash
systemic: wheezing
main treatment for anaphylaxis - ANSWER: epinephrine
Type 2 hypersensitivity is also known as what kind of reaction? - ANSWER:
cytoctoxic reaction, tissue specific
what cells are involved in type 2 hypersensitivity reaction? - ANSWER: Macrophages
what does type 2 hypersensitivity do to tissues? - ANSWER: can cause damage or
alter function of specific tissues
Examples of hypersensitivity type 2 - ANSWER: graves disease/ hyperthyroidism,
blood incompatibility
what is the difference between type 2 and 3 hypersensitivity? - ANSWER: type 2 is
organ specific; antibody binds to the antigen on the surface of the cell
type 3 is NOT organ specific; binds outside of the cell surface and is released into
