ANTIGEN QUIZ

lymph nodes

liver

bone marrow

blood stream

function as receptors for cytokine and CAMs

allow leukocytes to recognize antigen

are each expressed on only one cell type

are expressed on immune cells to mark them for separation

ability to enter the thyroid

degree of aggregation

dose

size

antigen is bound by a T cell membrane antibody

MHC molecules are not required

antigen exposure during T cell maturation is required

denaturation of antigen does not reduce epitope recognition

virus

bacteria

All of these

agent that causes a disease

low zone immunity

immunological ignorance

hypersensitivity

low zone tolerance

A protein molecule usually contains multiple epitopes

An epitope may be shared by two different antigens

B cells bind only processed antigen epitopes

Epitopes may be linear or assembled

antigen is hidden from the immune system in macrophages

new B and T cells with the appropriate antigen specificity must be produced in the bone marrow

innate immune effectors are eliminating antigen

innate immunity blocks the activation of adaptive immune effector cells

a hapten

an antigen

both an antigen and a hapten

an immunogen

spleen lymphoid tissue

MALT (mucosa associated

draining lymph nodes

blood circulation
