Pathogen-associated molecular pattern

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.[3]: 494 

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. The recognition of PAMPs by the PRRs triggers activation of several signaling cascades in the host immune cells like the stimulation of interferons (IFNs)[4] or other cytokines.[5]
