E)the cell surfaces of viruses

Question

Quizplus · Accepted Answer

Cells of the innate immune system possess receptors like Toll-like receptors (TLRs) on their surface which help them to recognize conserved macromolecules like lipopolysaccharides, flagellin, peptidoglycan, and nucleic acids that are characteristics of viruses and bacteria. This recognition results in the activation of various signaling pathways leading to the production of pro-inflammatory cytokines and chemokines that initiate a cascade of immune responses to eliminate the invading pathogens.
