Q

Hypersensitivity reaction
- Mediator & mechanism

Type 1 e.g. atopy
Type 2 e.g. blood transfusion
Type 3 e.g. erythema nodosum
Type 4 e.g. allergic contact dermatitis
Type 5 e.g neonatal hyperthyroid
Type 6 e.g. tumour rejection
A
  1. IgE - RAPID (30 mins) reaction to specific antigens
  2. IgG & IgM - intravascular reaction
  3. Immune complex - activate complement to cause local tissue damage
  4. Lymphocytes - secondary cellular response, appears 48-72hrs after exposure
  5. IgG - directed towards cell surface antigens
  6. Killer cells - lyse target cells coated by antibody
