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 ]
Even though, most classes of human pathogens are covered by CLRs, CLRs are a major receptor for recognition of fungi: [15] [16] nonetheless, other PAMPs have been identified in studies as targets of CLRs as well e.g. mannose is the recognition motif for many viruses, fungi and mycobacteria; similarly fucose presents the same for certain ...
The innate immune system relies on germline-encoded pattern recognition receptors (PRRs) to recognize distinct pathogen-associated molecular patterns (PAMPs). Upon recognition of a PAMP, PRRs generate signal cascades leading to transcription of genes associated with the immune response.
The first function described for TLR4 was the recognition of exogenous molecules from pathogens (PAMPs), in particular LPS molecules from gram-negative bacteria. [13] As pattern recognition receptor, TLR4 plays a fundamental role in pathogen recognition and activation of innate immunity which is the first line of defense against invading micro-organisms.
The ability of the immune system to recognize molecules that are broadly shared by pathogens is, in part, due to the presence of immune receptors called toll-like receptors (TLRs) that are expressed on the membranes of leukocytes including dendritic cells, macrophages, natural killer cells, cells of the adaptive immunity T cells, and B cells, and non-immune cells (epithelial and endothelial ...
Structure and domain organization of NOD2, a human NOD-like receptor. The nucleotide-binding oligomerization domain-like receptors, or NOD-like receptors (NLRs) (also known as nucleotide-binding leucine-rich repeat receptors), [1] are intracellular sensors of pathogen-associated molecular patterns (PAMPs) that enter the cell via phagocytosis or pores, and damage-associated molecular patterns ...

In contrast to the noninfectious inflammatory response produced by DAMPs, pathogen-associated molecular patterns (PAMPs) initiate and perpetuate the infectious pathogen-induced inflammatory response. [6] Many DAMPs are nuclear or cytosolic proteins with defined intracellular function that are released outside the cell following tissue injury. [7]
