module 4

Question 1

main role of NK cells.

Answer 1

immediate innate responses, kill infected or cancer cells. (perforin and granzyme) know “self” (MHC I) or not

Question 2

main role of basophil

Answer 2

allergic reactions and pathogens/parasites

Question 3

main role dendritic cells

Answer 3

• coordinate adaptive and innate (stimulate t cells)
• APC (antigen capture and presenting)

Question 4

main role neutrophil

Answer 4

• first responder
• enhance rest of immune response

Question 5

main role monocyte

Answer 5

• innate
• important dfferentiate later into machrophage DC etc
• phagocytoze pathogens

Question 6

main role eosinophil

Answer 6

• pathogens/ parosites
• promtoe allergic reactions

Question 7

T cell

Answer 7

made in bone marrow, mature in thymus.
adaptive immune repsponse.
differentiate into cytotoxic, helper, memory,

cell mediated

Question 8

b cell

Answer 8

made in bone marrow, mature in bone marrow.
adaptive immune respose.
differentiate into memory,

make ab
apc
humoral immunity

Question 9

differences between innate vs adaptive

Answer 9

innate- 1st, quicker, general, no memory

adaptive- slower, specific, memory

Question 10

how do vaccines innitae memory in immune responses

Answer 10

vaccines intoruduce harmless antigens into IS which stimulate IR and AB formation. memory is created. IS able to respond to specific second exposure much quicker.

Question 11

step by step vaccination to memory

Answer 11

• vaccine introduce harmless antigens
• antigens uptaken and presented (DC)
• antigens presented, activate T cells
• helper T see MHC II and stimuate B
• B cells begin to differentiate into plasma b and memory b, make antibodies
• B activate differentiation of Cytotoxic T to memory and effector
• memory cells remain for nexttimes
