Pathogen-associated molecular patterns, or PAMPs, are molecules associated with groups of pathogens, that are recognized by cells of the innate immune system. These molecules can be referred to as small molecular motifs conserved within a class of microbes. They are recognized by Toll-like receptors (TLRs) and other pattern recognition receptors (PRRs) in both plants and animals. A vast array of different types of molecules can serve as PAMPs, including glycans and glycoconjugates.
PAMPs activate innate immune responses, protecting the host from infection, by identifying some conserved nonself molecules. Bacterial lipopolysaccharides (LPSs), endotoxins found on the cell membranes of bacteria, are considered to be the prototypical class of PAMPs. LPSs are specifically recognised by TLR4, a recognition receptor of the innate immune system. Other PAMPs include bacterial flagellin (recognized by TLR5), lipoteichoic acid from gram-positive bacteria, peptidoglycan, and nucleic acid variants normally associated with viruses, such as double-stranded RNA (dsRNA), recognized by TLR3 or unmethylated CpG motifs, recognized by TLR9. Although the term "PAMP" is relatively new, the concept that molecules derived from microbes must be detected by receptors from multicellular organisms has been held for many decades, and references to an "endotoxin receptor" are found in much of the older literature.
In a study published in Science, Prof ... They found that the β-d-manno-heptoses are cross-kingdom small molecule pathogen-associated molecular patterns that activate the alpha-protein kinase 1 (ALPK1)-dependent innate immune signaling cascade ... DOI ... ....
Cytokine production is initiated by various stimuli, including pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs). These molecular signals are recognized by ...
The proteins and sugars on the surface of bacteria, viruses or other disease-causing pathogens have different shapes to any of the ones in the human body. These markers are pathogen-associated molecular patterns, commonly known as PAMPs.
However, no vaccine has shown lasting protection. ... “When humans get sick, their body’s defence system spots particular signs, called Pamps (pathogen-associated molecular patterns), on the outside of bacteria, viruses or other harmful germs.
The ability of these receptors to detect molecular patterns associated with pathogens depends on two types of proteins, called RLPs and RLKs, both of which can contain leucine-rich repeats—sections in ...
