Innate and Adaptive immunity Flashcards
1
Q
Intracellular killing by phagocytes
A
Adhesion to pathogen, phagocytosis of who cells or viral particles with passage to endosomes and lysosomes
2
Q
Extracellular killing
A
toxic metabolites, pore formation, induction of apoptosis
3
Q
Endocytosis
A
nonspecific pinocytosis or specific receptor mediated uptake, fusion with endosomes then with lysosomes containing degradative enzymes (intracellular killing)`
4
Q
Polymorphonuclear (PMN) leukocytes
A
eosinophils, basophils,neutrophils/ short lived
5
Q
