Toll-like receptor 4 – Wikipedia

Toll-like receptor 4 is a protein that in humans is encoded by the TLR4 gene. TLR4 is a transmembrane protein, member of the toll-like receptor family, which belongs to the pattern recognition receptor (PRR) family. Its activation leads to an intracellular signaling pathway NF-κB and inflammatory cytokine production which is responsible for activating the innate immune system.

Toll-Like Receptors | SpringerLink

The third class of molecules of the innate immunity includes cell surface receptors which recognize and bind whole bacteria or conserved bacterial molecules such as LPS. Receptors responding to this definition are CD14 and the newly discovered Toll-like receptors (TLRs), reviewed in (2, 4, 6-16).

Toll-Like Receptor Signaling Pathways and the Evidence… : Shock

Toll-like receptors are pattern-recognizing receptors that can be activated by microbial components or mammalian endogenous molecules. Upon activation, they induce the characteristic inflammation associated with innate immunity and promote the development of antigen-specific adaptive immunity ( 3-5 ).

Genetic approaches to the study of Toll-like receptor function.

The Toll-like receptor (TLR) family plays a role in sensing invading pathogens. Ten members have been reported to date, seven of which were found to recognize discrete bacterial components. Mouse models lacking each TLR and its signaling molecule are useful tools for the analysis of the innate immune system. PMID: 12106781 [Indexed for MEDLINE]

Where is tlr7 located? Explained by FAQ Blog

Who discovered Toll-like receptors? The first reported human toll-like receptor was described by Nomura and colleagues in 1994, mapped to a chromosome by Taguchi and colleagues in 1996. Because the immune function of toll in Drosophila was not then known, it was assumed that TIL (now known as TLR1) might participate in mammalian development.

Pattern recognition receptors (PRRs): toll-like receptors

Rossana Zaru, European Bioinformatics Institute EMBL-EBI, UK Toll-like receptors (TLRs) are pattern recognition receptors ( PRRs) which play a crucial in the initiation of innate immune response by detecting potential harmful pathogens. In mammals, the number of TLRs varies between species: human have 10 TLRs whereas mouse have 12 TLRs.

The evolution of vertebrate Toll-like receptors | PNAS

The Toll-like receptor (TLR) multigene family encodes important recognition receptors of the innate immune system that have been conserved in both the invertebrate and vertebrate lineages ( 1, 2 ). TLRs recognize a variety of endogenous and exogenous ligands; many of the latter are conserved molecules essential for pathogen survival.
