Recognition of extracellular or endosomal pathogen-associated molecular patterns is mediated by transmembrane proteins known as toll-like receptors (TLRs). [7] TLRs share a typical structural motif, the leucine rich repeats (LRR), which give them their specific appearance and are also responsible for TLR functionality. [8]
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
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 ...

They are types of pattern recognition receptors (PRRs), [2] and play key roles in the regulation of innate immune response. NLRs can cooperate with toll-like receptors (TLRs) and regulate inflammatory and apoptotic response. NLRs primarily recognize Gram-positive bacteria, whereas TLRs primarily recognize Gram-negative bacteria.
Toll-like receptor 1 (TLR1) is a member of the toll-like receptor (TLR) family of pattern recognition receptors (PRRs) that form the cornerstone of the innate immune system. [5] [6] [7] TLR1 recognizes bacterial lipoproteins and glycolipids in complex with TLR2. TLR1 is a cell surface receptor. [5]
Pattern-recognition receptors (PRRs) come into play here. These are receptors that recognize the gross, primarily structural features of molecules not innate to the host organism. PRRs include, for example, lipids with a totally different basic chemical structure. Such receptors are bound directly to cells of the immune system and cause ...
Once a DAMP is released from the cell, it promotes a noninfectious inflammatory response by binding to a pattern recognition receptor (PRR). [4] Inflammation is a key aspect of the innate immune response; it is used to help mitigate future damage to the organism by removing harmful invaders from the affected area and start the healing process.
