Question 5

Why is it a good strategy for a microbe to adhere to a receptor that plays a critical function for a host cell?

Accepted Answer

A) It ISN'T a good strategy-host cells could shift to a backup receptor and shut down production of the main receptor, preventing infection. 
B) If it's a receptor the cell MUST use, it doesn't have a backup system in place to switch to-so, even though it makes it susceptible to infection, it HAS to put that target out there.This benefits the microbe. 
C) Microbes want to evade detection and elimination by the immune system-the closer they can adhere to host cells, the less likely they are to trigger destructive immune responses.This would be similar to using a hostage as a shield in a police-standoff situation. 
D) It ISN'T a good strategy-by binding to receptors, microbes will be phagocytosed by cells and destroyed within them.
