Q

Type 1 IgE Mediated Hypersensitivity

A

Immediate
Local or systemic
Allergen activates IgE when binds to mast cells
At next exposure, the antigen binds with the surface IgE, releasing mediators and triggering the complement system

Q

Type II Cell Mediated

A 
Antigens deposit themselves on tissue
Antibody binds to tissue
Complement reaction causing inflammation
Phagocytosis
Cell death
17
Q

Type III Immune Complex Mediated

A

IgM binds to antigen and agglutinates

Accumulates and deposits in the tissue, specifically the blood vessel walls

18
Q

Serum sickness

A

Type III immune complex are formed in the blood and target tissues

19
Q

Arthus reaction

A

Type III immune complex are formed in the walls of blood vessels

20
Q

Type IV Cell Mediated

A

T cells activated from a chemical bound to the proteins in the skin
