Question

CR3 and CR4 can recognize LPS directly.
A. True
B. False

Answer 1

CR3 and CR4 can recognize LPS directly.

Step-by-step explanation:

CR3 and CR4 can recognize LPS directly.

TLRs, or Toll-like receptors, are proteins on the cell membrane of immune cells that recognize molecules characteristic of invaders. These TLRs can recognize molecules like lipopolysaccharides (LPS), which are found in bacterial cell walls.

Therefore, CR3 and CR4, which are types of TLRs, can indeed directly recognize LPS.
