WebJungo Kato, Camilla I. Svensson, in Progress in Molecular Biology and Translational Science, 2015. 1 Introduction. Pathogen-associated molecular pattern molecules (PAMPs), for example, lipopolysaccharide (LPS), are a diverse set of microbial molecules that share a number of different general “patterns,” or structures, that alert immune cells … 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 to recognize pathogens and thus, protect the host from infection. Although the term "PAMP" is relatively new, the concept that molecules derived from microbes … diabetic royal canin gato
