cell meditated response

Question 1

what types of lymphocytes are used in cell meditated immune response

Answer 1

t-lymphocytes

Question 2

what are the 3 other cells involved in the cell meditated response and what do they do

Answer 2

1. t helper cells - bind to the APC in order to to allow mitosis
2. memory cells - produce long term immunity for a specific pathogen
3. cytotoxin cells - destroy foreign cells by producing a protein called perforin which makes holes on the surface of the cell

Question 3

describe the process of a cell meditated response

Answer 3

1. pathogen is engulfed by a phagocyte forming it into a APC as they gain the pathogens antigens
2. a t helper cell with receptors compimentary to the antigens will then bind to the APC
3. this produces a response and so more t helper cells are activated in order to divide by mitosis and produce clones

Question 4

why do we need cloned t cells

Answer 4

• stimulate phagocytosis
• stimulate the production of b cells
• produce memory cells
• produce cytotoxins

Question 5

where do b cells mature and where are they produced

Answer 5

produced in the bone marrow and mature in the thymus gland
