Q

What are the three way neutrophils recognise bacteria foreign organisms?

A
  1. The neutrophils have receptors on the surface that recognise bacteria cells and other foreign bodies
  2. Opsonisation by the complement system which will bind a, compound called c3b which finds the surface of any foreign bodies allowing the neutrophils to find it easier
  3. Coat the foreign body with antibodies which will allow the neutrophil to sense the FC region ( te land of the antibody)

Q

What is your interferon system

A

Your interferon system is used to eliminate viruses as they do not have foreign bodies and infect host cells meaning they are not recognised by cells that phagocytosed. e.g Neutrophil.

Q

How does the interferon system work? (3 steps)

A

1.An infected cell will release interferon molecules.

2.The interferon molecules will bind to uninfected cells.

3.This causes the uninfected cells to change their proteins making it harder for the virus to enter the other cells.
