Lecture Set 6 : Part 2

Question 1

what are the properties of the adaptive immune response?

Answer 1

-acquired
-specific
-tolerance
-memory

Question 2

what is the acquired property?

Answer 2

-a pathogen must be encountered before the adaptive immune response is mounted

Question 3

what is the specific property?

Answer 3

-can mount a directed attack against a specific pathogen
-immunity to one pathogen does not mean there is immunity to another

Question 4

what is the tolerance property?

Answer 4

-inabilty to mount an adaptive immune response against self-antigens (molecules that naturally present on the surface of ones own body cells)
-immune cells that recognize self-antigens are destroyed during development

Question 5

what is the memory property?

Answer 5

-once a specific pathogen has been encountered immune cells will multiply and produce long living memory cells
-when the pathogen is encountered again, the memory cells will mount a faster and stronger response

Question 6

what are the 2 types of responses within the adaptive immune response?

Answer 6

-primary response
-secondary response

Question 7

what is the primary response?

Answer 7

-the first time a new pathogen is encountered
-adaptive response is weak
-major result from this response is the production of immunologic memory

Question 8

what is the secondary response?

Answer 8

-can be the 2nd or 100th time a pathogen is encountered
-memory cells are ready to respond so the adaptive response is stronger and faster
-sometimes the response can be so quick that disease does not occur (immunity)

Question 9

what are the 2 branches of the adaptive immune response?

Answer 9

-humoral (antibody mediated) immunity
-cellular (cell mediated) immunity
