Examples include LPS, porins, peptidoglycan, lipoteichoic acids, mannose-rich glycans, flagellin, bacterial and viral genomes, mycolic acid, and lipoarabinomannan. Danger-associated molecular patterns or DAMPs are unique molecules displayed on stressed, injured, infected, or transformed human cells also be recognized as a part of innate immunity.
Pathogen-associated molecular pattern - Wikipedia
Pathogen-associated molecular patterns (PAMPs) are small molecular motifs conserved within a class of microbes, but not present in the host. [1] They are recognized by toll-like receptors (TLRs) and other pattern recognition receptors (PRRs) in both plants and animals. [2] This allows the innate immune system to recognize pathogens and thus, protect the host from infection.

Pathogen Associated Molecular Pattern - ScienceDirect Topics
Introduction. Pathogen-associated molecular patterns (PAMPs) are patterns conserved for a whole class of pathogens [1, 2].The capacity of the host to recognize these patterns and mount an immune response results in broad spectrum resistance to all pathogens displaying this molecular pattern, and for which the pathogen has not evolved ways to evade or counteract the resistance response.

Examples of PAMPs. Lipopolysaccharides (LPS): These are found on the outer membrane of Gram-negative bacteria. They are recognized by the Toll-like receptor 4 (TLR4) on immune cells. Peptidoglycan: This is a component of the cell wall of both Gram-positive and Gram-negative bacteria. It is recognized by several PRRs, including NOD-like ...
