cells of innate immune system

Question 1

dendritic cells role

Question 2

macrophages cells role

Question 3

mast cells role

Question 4

neutrophils cells role

Answer 4

first WBC recruited to acute inflammation - in response to chemotaxis
first line of defence in response to invading pathogens - phagocytosis + release of antimicrobial factors from granules

Question 5

basophils cells role

Question 6

eosinophils cells role

Question 7

gamma delta T cells role

Question 8

natural killer cells role

Question 9

what is the main constituent of pus

Answer 9

neutrophils

Question 10

how do neutrophils directly interact with pathogens

Answer 10

via recognition of pamps
by neutrophil pattern recognition receptors

Question 11

how do neutrophils directly interact with pathogens

Answer 11

via recognition of pamps
by neutrophil pattern recognition receptors

Question 12

how do neutrophils indirectly interact with pathogens

Answer 12

through recognition of opsonised microbes by Fc receptors or complement receptors
the phagosome undergoes a rapid maturation process that involves the fusion with neutrophil granules ,, reactive oxygen species are generates - to kill pathogen
