Marker molecules found on pathogens
Pathogen-associated molecular patterns (PAMPs) are small molecular motifs conserved within a class of microbes, but not present in the host. They are recognized by toll-like receptors (TLRs) and other pattern recognition receptors (PRRs) in both plants and animals. This allows the innate immune system … Meer weergeven A vast array of different types of molecules can serve as PAMPs, including glycans and glycoconjugates. Flagellin is also another PAMP that is recognized via the constant domain, D1 by TLR5.
