Gene organization and evolutionary history. The Drosophila genome contains nine genes that encode Toll and related receptors (dToll1 - dToll9), whereas ten Toll-like receptor (TLR) genes have been identified in mice and humans [1,2,3,4,5,6].The human and murine TLR2 genes and the murine TLR4 gene have two 5' non-coding exons followed by a third coding exon.
One of the most important PRR families is the Toll-like receptors ... a novel human Toll-like receptor preferentially expressed in immune cells. Biochim Biophys Acta. 2001; 518:157–61.

Members of the Toll-like receptor (TLR) family are key regulators of both innate and adaptive immune responses. The function of TLRs in various human diseases has been investigated by comparison of the incidence of disease among people having different polymorphisms in genes that participate in TLR signaling.
A small number of Toll-like receptors can detect a broad range of human pathogens, as well as a variety of other molecules that indicate tissue damage, by a process called pattern recognition ...
It is with this idea in mind that Toll-like receptors (TLRs) have emerged as a focal-point of biomedical research, as this small family of proteins serves as one of the earliest determinants of immune activation. ... or an AIM2-like Receptor (ALR). The human and mouse genomes encode multiple NLRs, including Nlrp1, Nlrp3, Nlrc4, and Nlrp12 ...
For the innate response, a family of cellular receptors called Toll-like receptors (TLRs), which recognize molecules unique to microbes, constitutes the primary strategy for self versus non-self discrimination. ... (TIR) domain that is homologous to the intracellular domain of IL-1 receptor family members. In mice and humans combined there are ...
Toll-like receptors (TLRs) are a family of transmembrane receptors that have been preserved throughout evolution and which selectively recognize a broad spectrum of microbial components and endogenous molecules released by injured tissue. Identification of these ligands by TLRs triggers signalling p …
Toll-like receptors (TLRs) are vital components of the innate immune system, serving as the first line of defense against pathogens by recognizing a wide array of molecular patterns. This review summarizes the critical roles of TLRs in immune surveillance and disease pathogenesis, focusing on their structure, signaling pathways, and ...

Receptors involved in the oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine-mediated synthesis of interleukin-8. A role for Toll-like receptor 4 and a ...
The 10 human and 12 mouse Toll-like receptors (Table 9.10) are structurally similar to the IL-1 receptor and recognize various patterns that are common to groups of pathogens [485]. TLR ligation results in cellular activation, mainly of macrophages, but also many other inflammatory and tissue cells.
Toll-like receptors were discovered as proteins playing a crucial role in the dorsoventral patterning during embryonic development in the Drosophila melanogaster (D. melanogaster) almost 40 years ago. ... In 1997, the human homolog was reported and the receptor was named the Toll-like receptor 4 (TLR4) that recognizes lipopolysaccharide (LPS ...
A family of evolutionarily conserved Toll-like receptors plays a pivotal role in initial host defence against invading pathogens. These receptors recognise PAMPs that are common to a broad range of microorganisms, as well as damage-associated molecular patterns (DAMPs) [27]. To date, 11 members of the TLR family have been characterised in mammals.
Toll-like receptor 2 also known as TLR2 is a protein that in humans is encoded by the TLR2 gene. [5] TLR2 has also been designated as CD282 (cluster of differentiation 282). TLR2 is one of the toll-like receptors and plays a role in the immune system.TLR2 is a membrane protein, a receptor, which is expressed on the surface of certain cells and recognizes foreign substances and passes on ...
