The binding of toll-like receptors on dendritic cells and macrophages to LPS from bacteria stimulates the secretion of
A)cytokines.

C)PAMPs.
D)peptidoglycans.

Question

Quizplus · Accepted Answer

Toll-like receptors (TLRs) recognize various pathogen-associated molecular patterns (PAMPs) including lipopolysaccharides (LPS) from bacteria. The binding of TLRs on dendritic cells and macrophages to LPS stimulates the secretion of cytokines. Cytokines are important for the initiation of the innate immune response and act as chemoattractants for immune cells to the site of infection.
