Q

Hypersensitivity type III

A

Antigen-antibody complexes are deposited in tissue (immune complex disease)

17
Q

Hypersensitivity type IV

A

Activation of cytotoxic T cells (delayed cell mediated) ex type 1 diabetes

18
Q

Autoimmune (hypersensitivity)

A

The immune system response is absent or depressed as a result of a primary or secondary disorder (Primary- T cells, B cells, NK cells; Secondary- HIV, malnutrition, aging)

19
Q

Phases of adaptive immune response

A

Recognition (antigen presenting cell attaches) -> amplification (differentiation) -> effector (elimination of antigens) -> termination (apoptosis) -> memory
