13542 IUPAC Gold Book - pathogen-associated molecular pattern 10.1351/goldbook.13542 13542 current initialism: PAMP 1 Describing repetitive motifs of molecules such as lipopolysaccharide (LPS), peptidoglycan, lipoteichoic acids, and mannans, which are widely expressed by microbial pathogens but are not present on host tissues. They are therefore utilized by the pattern recognition receptors (PRRs) of the immune system to distinguish pathogens from self-antigens. immune system https://goldbook.iupac.org/terms/view/13271 pattern recognition receptors (PRRs) https://goldbook.iupac.org/terms/view/13543 self-antigens https://goldbook.iupac.org/terms/view/12914 PAC, 2012, 84, 1113.
