Immune Responses - Internal Defenses
Cards in this deck (5)
- 1Internal DefensesAntimicrobial proteins discourage microbial growth.
- 2Interferons (IFN)Produced by virally infected lymphocytes and macrophages.
Diffuse to neighboring cells to induce synthesis of antiviral proteins. - 3TransferinsIron-building proteins inhibit bacterial growth by reducing available iron.
- 4Complement SystemInactive proteins in blood plasma.
When activated enhance immune allergic and inflammatory reactions.
Damage bacterial cell wall = Cytolysis.
Causes chemotaxis, they chemically call phagocytic cells.
Causes vasodilation and increase blood flow.
Promotes opsonization of bacteria and increase phagocytosis. - 5What is opsonisation?The process by which a pathogen is marked for ingestion and destruction by a granulocyte.
