Innate and adaptive Immunity Flashcards
Mucus composition
glycoproteins proteoglycans, and enzymes
lysozyme in tears and saliva
Effector mechanisms
effector cells engulf bacteria, kill virus-infected cells, or attack protozoan parasites
batter of serum proteins called complement that help the effector cells by marking pathogens with molecular flags
How do macrophages react in innate immunity?
They engulf bacteria through receptor-mediated phagocytosis and degrade the contents of the phagosome after combining with a lysosome
They release inflammatory cytokines
Source of macrophages
monocytes (from myeloid progenitor) (from hematopoeitic stem cell) from/in bone marrow
What activates alphabeta-T cells?
Peptides, proteins
What activates B cells?
Peptides, proteins, Glycoproteins/Proteoglycans, Carbohydrates, Glycolipids and phospholipids,
