Adaptive Immunity - Mucosal immunity Flashcards
1
Q
Absorption and secretion in the GI?
A
2
Q
What defences do we have in our GI tract?
A
3
Q
Why do we get ill despite having defences?
A
4
Q
What does GALT (Gut associated lymphoid tissue) include?
A
5
Q
What are the 4 ways the immune system samples?
The mucosal immune system constantly samples the gut lumen? Why is it sampled?
A
-To ensure that the bacteria is pathogenic in order to try limit inflammation
6
Q
What Mucosal surfaces do we have to try limit inflammation?
A
7
Q
How is the GI tract kept in an anti inflammatory environment? (maintain mucosal defences)
A
8
Q
Summarise Mucosal surfaces?
A
- At mucosal surfaces antibody secretion is vital to maintain integrity
-These surfaces aim to produce an immune response to clear the pathogen whilst reducing tissue damage
