Question

Which one of the following is a class of transmembrane pattern recognition receptor?

1) NOD-like receptors
2) Toll-like receptors
3) RIG-like receptors
4) Antibodies

Answer 1

Toll-like receptors (TLRs) are a class of transmembrane pattern recognition receptors that play a key role in the innate immune response by recognizing pathogens. Hence the correct answer is option 2

Step-by-step explanation:

The class of transmembrane pattern recognition receptor is Toll-like receptors (TLRs). They are proteins localized on the cell membrane of immune cells and recognize molecules that are characteristic of broad classes of invaders. TLRs are a type of pattern recognition receptor (PRR) that play a key role in the innate immune response by recognizing pathogens and initiating an immune response.

Hence the correct answer is option 2
