An Example of Pathogen-Associated Molecular Patterns (PAMP) Is

Question

An example of pathogen-associated molecular patterns (PAMP) is
A) cell-surface proteins.
B) flagellin proteins.
C) lipopolysaccharide (LPS).
D) pilus.

Accepted Answer

Lipopolysaccharide (LPS) is a PAMP that is found in the outer membrane of Gram-negative bacteria. It is a complex molecule that consists of a lipid A core, an inner core, and an O-antigen. LPS is recognized by Toll-like receptor 4 (TLR4) on the surface of immune cells, which triggers an inflammatory response.
