, Type 1: Allergic reaction, Mediated by IgE,
Inflammation due to mast cell degranulation
Local symptoms:
-itching
-rash
Hypersensitivity: Type
Systemic symptoms:
1
-wheezing
Most dangerous = anaphylactic reaction
systemic response of hypotension, severe
bronchoconstriction
Main treatment: epinephrine reverses the
effects
, Type 2: Cytotoxic reaction; tissue specific (ex:
thyroid tissue)
Macrophages are the primary effectors cells
involved
Can cause tissue damage or alter function
Hypersensitivity: Type
Grave's disease (hyperthyroidism) - example of
2
altering thyroid function, but does not destroy
thyroid tissue
Incompatible blood type- example of
cell/tissue damage that occurs; severe
transfusion reaction occurs and the transfused
erythrocytes are destroyed by agglutination
or complement-mediated lysis.
, Type 1 Hypersensitivity
Organ Specific
Antibody binds to the antigen on the cell
surface
Type 1
Hypersensitivity VS.
Type 2 Hypersensitivity
Type 2
