Flashcards in Immunology Deck (17):
1

Name and draw the 5 different antibodies

MADGE

2

Name the 2 different lymphoid organs

Primary and secondary

3

Give 2 examples of primary lymphoid organs

Bone marrow and thymus

4

What are the 2 functions of primary lymphoid organs

Produce lymphocytes and where they mature. Selection and deletion of auto-reactive cells to prevent autoimmunity

5

Give 2 examples of secondary lymphoid organs

lymph nodes and spleen

6

What i the function of secondary lymphoid organs

Maintain mature, naive lymphcytes and initiate the adaptive immune response

7

Where are B cells produced

bone marrow

8

What do b cells have on their surface

membrane bound immunoglobin

9

Where do T cells mature

in the thymus

10

What separates a helper t cell from a cytotoxic t cell

Helper = CD4 surface receptor
Cytotoxic = CD8 surface receptor

11

Give some characteristic of an adaptive immune response

1. Has memory
2. Occurs in specialised places
3. Has a unique antigen receptor on each lymphocyte
4. Response is heightened second time

12

What cells are involved in an adaptive immune response

B and T cells

13

Describe some characteristics of an innate immune response

1. Occurs locally
2. There is no memory
3. response is immediate and pathogen specific

14

What cells are involved in an innate immune response

Neutrophils and macrophages

15

What would the immune systems response be to a viral infection?

Recruitment of natural killer and cytotoxic T cells.

16

WHat would the immune response to a bacterial infection be

An innate response. Involving phagocytosis and antibodies

17

How do T and B cells work together?

T cells produce cytokine which bring about the production of antibodies. B cells prodoce antibodies
