Innate: Chemical Mediators
- Promote phagocytosis and inflammation
- Complement
- 20 proteins in blood circulation
- activated in cascade form
- Form membrane attack complexes.
(MAC) These make channels through
the plasma membrane
- attach to surface of bacterial
cells which stimulates
phagocytosis.
- Attract immune system
to site of infection and
promote inflammation
- Classical or Alternative pathway
- alternative: - innate
immunity. C3 binds with
the foreign substance
which attracts
macrophages.
- classical: adaptive immunity.
Requires antibodies to
produce antigens.
- Interferons
- Prevent viral infection
- Produced by infected cell
but cause the neighboring
cells to produce antiviral
proteins.
