Lecture 14

Question 1

What is the function of T-cells?

Answer 1

cell mediated immunity

Question 2

What is the function of B-cells?

Answer 2

antibody mediated immunity

Question 3

How does the secondary immune response differ from the primary immune response?

Answer 3

The lag time is not as great (starting of with a greater number of cells- memory)

Question 4

Th lymph nodes has _cells on the inside and _ cells on the outside:

Answer 4

T-cells

B-cells

Question 5

What is the response of B-cells to antigen? What is the benefit of this response?

Answer 5

These are antibody making factories, synthesising large amounts of Y-shaped proteins. Anti-body can block things, the macrophages can see them and will eat them

Question 6

What conditions are required for the T-cell to be able to recognise the antigen?

Answer 6

Only able to recognise the protein when it is presented in a special MHC molecule that allows peptides to be able to fit within it

Question 7

How do the antigens typically get to the T-cells?

Answer 7

Dendritic cells capture the antigen and bring it to the T-cell

Question 8

What is the function of killer T-cells?

Answer 8

Use toxic granule proteins to kill the virus

Question 9

What is the function of helper T-cells?

Answer 9

make cytokines and surface cells to help activate other cells within the immune system
