Flashcards in Adaptive/Acquired Immunity Deck (17):
1

antigen (Ag)

antibody generator-substance that binds to a lymphocyte receptor

2

antigenic molecule

has the ability to be bound by a specific antibody (Ab)

3

immunogen

substance that induces an immune response when injected into an individual

4

what makes a good antigen (antigenicity)

host genetics, size, route of administration, adjuvant, complexity, foreignness, dose, chemical stability

5

what are antigen presenting cells (APC)?

macrophages, lymphocytes (B), dendritic cells

6

adaptive immune response intracellular antigens

cellular immune response, T lymphocytes, cytotoxic T cells

7

adaptive immune response extracellular antigens

humoral immune response, B lymphocytes, antibodies

8

what do T cells provide immunity to?

intracellular bacteria, intracellular virus, fungi, protozoa, tumors

9

when is the only time that T cells recognize an antigen?

when it is presented on the surface of APC by self MHC molecules

10

what response processes are mediated by T cells?

infected cells are killed, infected cells are activated and destroy the intracellular organism

11

adaptive humoral immune response; passive/artificial

immunoglobulins

12

adaptive humoral immune response; passive/natural

transplacental, colostrum, egg

13

adaptive humoral immune response; active/artificial

vaccination

14

adaptive humoral immune response; active/natural

diseases

15

classes of immunoglobulins (Ig)

IgG, IgM, IgA, IgD, IgE

16

IgA

saliva, milk, gastrointestinal fluids

17

what is the most common form of immunization?

vaccines
