module 4 - 12.8 functions of antibodies Flashcards
1
Q
what is a complement?
A
- proteins in plasma of the blood
- complement cascade
- disrupt bacterial cell membranes
- cause cell lysis
2
Q
what are opsonins?
A
- any substance that helps phagocytosis
- are immunoglobulins produced by B cells
- protects body against foreign antigens through immune response
3
Q
what are cytokines?
A
- small proteins that control growth & activity of other immune system cells and blood cells
- they signal immune system when released
- help the body’s immune & inflammation response
4
Q
what are interleukins?
A
- type of cytokine
- produced by many other body cells
- activate and differentiate immune cells
5
Q
what are interferons?
A
- proteins that are part of your natural defences
- tells immune system that pathogens are in the body
- trigger T cells
- they ‘interfere’ so stop them multiplying
6
Q
what is immobilization?
A
they stop bacteria moving
7
Q
what is agglutination?
A
when pathogens are clumped together
8
Q
what is lysis?
A
bacteria are destroyed by digestion so rupture bacterial membrane
9
Q
what is opsonisation?
A
pathogens are coated with antibodies that identifies them as foreign cells
10
Q
what are antitoxins?
A
toxins produced by bacteria are neutralised
