Intro To Immune System Flashcards
1
Q
What is innate immune system made up of?
A
Barriers that keep viruses, bacteria + parasites + other foreign particles out of body or limit their ability to spread + move throughout the body
2
Q
How do immune cells know when to get to work?
A
Immune system detects danger through series of pathogen associated molecular patterns (PAMPs) or danger associated molecular pattern molecules (DAMPs)
3
Q
What is a PAMP?
A
Pathogen associated molecular pattern Small molecular motif conserved within class of microbes
4
Q
What is DAMPs?
A
Danger associated molecular pattern
Are molecules released by stressed cells undergoing necrosis which is uncontrolled mode of cell death
5
Q
How are PAMPs and DAMPs recognised?
A
Recognised by pattern recognition receptors (PRRs) on immune cells
