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 ]
Plant PRRs either exist as surface-localized receptor kinases (RKs) or receptor-like proteins (RLPs) that contain multiple ligand-binding ectodomains that perceive PAMPs or DAMPs. [41] The corresponding PAMPs for FLS2 and EFR have been identified. [39] Upon ligand recognition, the plant PRRs transduce "PAMP-triggered immunity" (PTI). [42]
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 ...
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 ...
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]

As it does every year, NORAD, the North American Aerospace Command, tracked Santa on his trip around the world on Christmas Eve so children and families could see where he was.
