Receptors on the surface of phagocytes that recognize certain types of highly conserved molecules that play essential roles in viruses and bacteria are called _______.
A)pattern recognition receptors
B)PRRs
C)Toll-like receptors
D)TLRs
E)All of these are correct.

Question

Quizplus · Accepted Answer

All the options are correct. Pattern recognition receptors (PRRs) are receptors on the surface of phagocytes that recognize highly conserved molecules in viruses and bacteria. Toll-like receptors (TLRs) are a type of PRRs that recognize pathogen-associated molecular patterns (PAMPs) on the surface of microbes and trigger an innate immune response. Therefore, both choices A and B are correct, as well as choices C and D. Therefore, the correct answer is E, "All of these are correct."
