1

These lymphocytes protect against viruses, fungi, facultative organisms

T lymphocytes

2

To tell these apart on a blood smear, you must use a supravital stain

T lymphocytes

3

T lymphocytes play a role in humoral immunity by

cytokine production

4

T lymphocytes acount of what percent of peripheral blood leukoctes?

70-80%

5

These lymphocytes live in the lymph nodes and spleen

T lymphocytes

6

Thymosin helps these lymphocytes mature in the thymus

T lymphocytes

7

These lymphocytes produce cytokines which leads to the activation of B cells

Helper T lymphocytes

8

Helper T lymphocytes account for what percent of T lymphocytes?

40-60%

9

This is the surface marker on Helper T lymphocytes

CD4

10

These lymphocytes downregulate the immune response

Cytotoxic T cells

11

These lymphocytes can kill virus infected cells, tumor cells, or transplant tissue

Cytotoxic T cells

12

Perforin is used by which lymphocyte to kill other cells?

Cytotoxic T cells

13

The surface marker is on Cytotoxic T cells

CD8

14

These lymphocytes are activated by the release of cytokines

B lymphocytes

15

B lymphocytes are part of what kind of immunity?

B lymphocytes

16

These lymphocytes differentiate into plasma cells

B lymphocytes

17

B lymphocytes account for what percent of peripheral blood lymphocytes?

5-15%

18

B lymphocytes live in

the spleen and tonsils (50%)

19

B lymphocytes that do not become plasma cells usually become

Memory B cells

20

These cells rapidly produce antibody on a second exposure to an antigen (amnestic response)

Memory B cells

21

These cells gush antibody for 3-4 days

plasma cells

22

These cells are full of endoplastic reticulum

plasma cells

23

These cell differentiate when exposed to an antigen with Helper T cells (cytokines)

plasma cells

24

These cells have the same specificity from the cell it was derived from

plasma cells

25

These cells are attracted to opsonized particles

macrophages

26

These cells present T and B cells particles for destruction

macrophages

27

These cell produce enzymes, activate plasminogen, denature collagen

macrophages

28

Do macrophages produce complement components?

Yes, C1

29

This cell has an Fc receptor for antibodies

macrophages

30

This cell has a receptor for complement

macrophages

31

These cells have Fc receptor AND the ability to destroy tumor cells

Killer cells

32

These cells stimulate cytotoxic T cells

Helper T cells

33

These cells secrete lymphokines

Helper T cells

34

These cells DO NOT secrete lymphokines

Cytotoxic T cells
