neutrophils

Question 1

what are the different functions of neutrophils

Answer 1

phagocytosis, degranulation and NETs

Question 2

describe the neutrophil process of phagocytosis

Answer 2

pathogen releases chemical signals that attract neutrophils, neutrophils use PRRs to bind to and phagocytose

Question 3

describe the neutrophil process of degranulation

Answer 3

this is the release of anti-bacterial proteins from neutrophil granules into extracellular fluid, killing extracellular pathogens(bacteria and fungi), could cause tissue damage and (possibly)systemic inflammation

Question 4

describe the neutrophil process of NETs

Answer 4

NETs = Neutrophil Extracellular Traps
cell commits suicide in order to trap and kill pathogen, NETs are composed of the cells DNA, histones, enzymes and granular proteins

Question 5

what type of cell are NK(natural killer) cells

Answer 5

lymphocytes

Question 6

what cells do NK cells target and kill

Answer 6

specifically infected or abnormal(cancerous) cells

Question 7

how do they kill other cells

Answer 7

they release cytotoxins that cause the cell to undergo apoptosis
