Specific immunity

HideShow resource information
What is involved in specific immunity?
B and T lymphocytes
1 of 19
What is the body infected by?
bacterium with specific antigens on surface
2 of 19
What is the process called that happens here?
phagocytosis
3 of 19
hat happens to the antigen from bacterium?
they are inserted in membranes on MHC proteins,
4 of 19
What do these become?
antigen presenting cells
5 of 19
What do T helper cells bind to?
the antigen
6 of 19
then what do they do?
divide to become a clone of active T helper cells and memory cells
7 of 19
What do the B cells do?
they engulf bacterium
8 of 19
where is the antigen inserted to?
the membrane
9 of 19
What do T helper cells bind to ?
B cells displaying the same antigen and release cytokines
10 of 19
What do cytokines stimulate?
activated B effector cells to divide to produce clone of plasma cells and memory cells
11 of 19
What do plasma cells produce?
antibodies
12 of 19
The Production of T cells
The production of T cells
13 of 19
What do infected cells have on their surface?
pathogen antigens
14 of 19
What do T killer cells do?
use complimentary receptors to bind to these antigens
15 of 19
What happens to T cells?
They become active T killer cells
16 of 19
What do cytokines from T helper cells stimulate?
to divide to produce a clone of active T killer cells which increases the number of cells to fight the infection
17 of 19
What do these T killer cells bind to?
antigens on the surface of the infected ell and release chemicals which either cause the infected cell to self destruct or swell and burst
18 of 19
What do T and B memory cells do?
ensure the immune system can deal with any reinfection by the same pathogens
