Flashcards in CH 16-2 Deck (30):
1

1. Humoral Immunity

B Cells

2

2. CMI (cell mediated immunity

T Cells

3

3. Th1 needed for activation

T Cells

4

4. needs cytokines for activation

B Cells/T Cells

5

5. forms antibodies

B Cells

6

6. have monospecific TCRs for binding MHC presenting antigens

T Cells

7

7. may require Th2 for induction

B Cells

8

8. forms memory cells

B Cells/T Cells

9

9. clones have BCRs for recognizing epitopes

B Cells

10

10. will kill human cells that are virally infected, cancerous, or foreign

T Cells

11

11. needs an antigen to be “challenged"

B Cells/T Cells

12

12. not well understood; possibly BCR

IgD

13

plays role in allergies by triggering release of histamines from mast & basophils cells

IgE

14

most numerous in serum, crosses placenta, activates complement

IgG

15

secreted as dimer in tears, saliva, breast milk

IgA

16

large pentamer, can be BCR, activates complement

IgM

17

17. Ab binding causes lyses G(-) bacteria & activates inflammation by causing degranulation of mast & basophil cells

activation of complement

18

18. Ab blocks adhesion proteins in bacteria & viruses to prevent attachment

neutralization

19

19. IgG coats microbe & Fc has receptor for neutrophils & macrophages stimulating phagocytosis

opsonization

20

20. Ab causes hydrogen peroxide and ozone production to kill bacteria

oxidation

21

21. Ab crosslinks microbes causing them to precipitate

agglutination

22

22. Ab binding causes NK lymphocytes to kill by apoptosis

ADDC

23

23. Response lasts longer

secondary

24

24. Makes IgM first

primary

25

25. Needs lower antigen concentration to trigger response

secondary

26

26. Makes IgG first

secondary

27

27. Produces a higher titer of antibodies

secondary

28

28. Requires several days before antibodies are made

primary

29

29. first memory cells are made

primary

30

30. depends on the activity of memory cells

secondary
