Question

What do phagocytes have to recognize "pathogen-associated molecular patterns" (PAMPs)?

a) Phagocytes recognize PAMPs through T-cell receptors.
b) Phagocytes recognize PAMPs using Toll-like receptors.
c) Phagocytes rely on antibodies to identify PAMPs.
d) Phagocytes don't recognize PAMPs.

Answer 1

Phagocytes recognize PAMPs using Toll-like receptors.

Step-by-step explanation:

Phagocytes recognize "pathogen-associated molecular patterns" (PAMPs) using Toll-like receptors (TLRs). PAMPs are carbohydrate, polypeptide, and nucleic acid 'signatures' expressed by viruses, bacteria, and parasites. Toll-like receptors are pattern recognition receptors (PRRs) found on phagocytes that can recognize these PAMPs.

Answer 2

Phagocytes detect PAMPs using Toll-like receptors, crucial for initiating an immune response and destroying pathogens. Option b) Phagocytes recognize PAMPs using Toll-like receptors is correct.

Step-by-step explanation:

Phagocytes recognize pathogen-associated molecular patterns (PAMPs) using Toll-like receptors (TLRs), which are a type of pattern recognition receptor (PRR) found on the surface of phagocytes.

These receptors bind to PAMPs on the pathogens' surface, which triggers the phagocytosis and destruction of the invading microbes.

This is crucial for the innate immune response to effectively clear pathogens from the body. Option b) Phagocytes recognize PAMPs using Toll-like receptors is correct.
