Type 1 Hypersensitivity mechanism
free antigen cross links IgE on presensitized mast cells and basophils triggering release of vasoactive amines. after antigen exposure rapid response due to preformed antibodies
type 2 hypersensitivity mechanism
IgM, IgG bind to free antigen on "enemy" cell, leading to lysis by complement or phyagocytosis
1. opsonize cells or activate complement
2.antibodies recruit neutrophils and macrophages that incite tissue damage
3. bind normal cellular receptors and interfere with functioning

disease tends to be specific to tissue or site where antigen is found
type 3 hypersensitivity mechanism
antigen-antibody (IgG) complexes activate complement which attracts neutrophils; neutrophils release lysosomal enzymes also complement acts. immune complexes can deposit and cause damage in kidneys, joints, etc

can be associated with vasculitis and systemic manifestations
type 4 hypersensitivity mechanism
sensitized t lymphocytes encounter antigen and then release lymphokines (leads to macrophage activation)

only type to not involve antibodies. cell mediated therefore, not transferable by serum.
