IMMUNE MECHANISM:
Mediator release from IgE-sensitized mast cells and basophils
type 1
IMMUNE MECHANISM:
Cell destruction due to Ab and complement, opsonization, or ADCC
Cell function INHIBITED by Ab binding
Cell function STIMULATED by Ab binding
type 2
IMMUNE MECHANISM:
Ag-Ab complex activates complement proteins
Neutrophils are recruited and release lysosomal enzymes that cause tissue damage
type 3
IMMUNE MECHANISM:
Ag-sensitized Th1 cells release cytokines that recruit macrophage and induce inflammation or activate cytotoxic T cells to cause direct cell damage.
