liver

lymph nodes

bone marrow

blood stream

TRUE ANSWER : ?
YOUR ANSWER : ?

A molecule that can be covalently linked to a non-immunogenic antigen to make it an immunogen is called a (n)

adjuvant

carrier

hapten

mitogen

TRUE ANSWER : ?
YOUR ANSWER : ?

CD antigens

are each expressed on only one cell type

are expressed on immune cells to mark them for separation

function as receptors for cytokine and CAMs

allow leukocytes to recognize antigen

TRUE ANSWER : ?
YOUR ANSWER : ?

The antibiotic penicillin is a small molecule that does not induce antibody formation. However, penicillin binds to serum proteins and forms a complex that in some people induces antibody formation resulting in an allergic reaction. Penicillin is therefore

an immunogen

a hapten

both an antigen and a hapten

an antigen

TRUE ANSWER : ?
YOUR ANSWER : ?

A virus vaccine that can activate cytotoxic T cells must contain

a high dose of virus particles

virus peptides

an adjuvant to stimulate T cell division

live virus

TRUE ANSWER : ?
YOUR ANSWER : ?

Antigen, when injected in the body activates its specific lymphocytes in the

blood circulation

MALT (mucosa associated

draining lymph nodes

spleen lymphoid tissue

TRUE ANSWER : ?
YOUR ANSWER : ?

During the lag period between antigen contact and detection of adaptive immunity,

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

innate immunity blocks the activation of adaptive immune effector cells

antigen is hidden from the immune system in macrophages

innate immune effectors are eliminating antigen

TRUE ANSWER : ?
YOUR ANSWER : ?

Which of the following is incorrect with regard to antigen epitopes?

An epitope may be shared by two different antigens

Epitopes may be linear or assembled

A protein molecule usually contains multiple epitopes

B cells bind only processed antigen epitopes

TRUE ANSWER : ?
YOUR ANSWER : ?

agent that causes a disease

All of these

bacteria

virus

TRUE ANSWER : ?
YOUR ANSWER : ?

Very low doses of antigen may induce

immunological ignorance
