Question

________ on phagocytes bind to PAMPs on bacteria, which triggers the uptake and destruction of the bacterial pathogens?

a) Antibodies
b) Cytokines
c) Toll-like receptors
d) Interferons

Answer 1

Toll-like receptors (TLRs) on phagocytes bind to pathogen-associated molecular patterns (PAMPs) on bacteria, triggering the uptake and destruction of the bacterial pathogens.

Step-by-step explanation:

Toll-like receptors (TLRs) on phagocytes bind to pathogen-associated molecular patterns (PAMPs) on bacteria. This binding triggers the uptake and destruction of the bacterial pathogens through a process called phagocytosis. TLRs are a type of pattern recognition receptors (PRRs) found on phagocytes, which are a type of immune cell.
