How does a neutrophil kill foreign invaders? |
|
Definition
Uses NADPH to produce a superoxide ion that promotes killing of the invader via phagocytosis |
|
|
Term
What are the steps required for neutrophil killing? |
|
Definition
1) recognition of foreign invader through cell-surface receptors
2) invagination of cell membrane which is facilitated when the bacteria are coated with host defense proteins, opsonins
3) phagosome formation: bacteria exposed to enzymes that were originally positioned on the cell surface. NADPH oxidase is activated, secretion of the superoxide into the phagosome causing an oxidative burst
4) killing of pathogens |
