Toll-like receptors (TLRs) are the important mediators of inflammatory pathways in the gut which play a major role in mediating the immune responses towards a wide variety of pathogen-derived ligands and link adaptive immunity with the innate ...
Toll-like receptors (TLRs) are an important family of receptors that constitute the first line of defense system against microbes. They can recognize both invading pathogens and endogenous danger molecules released from dying cells and damaged tissues and play a key role in linking innate and adaptive immunity. TLRs are widely distributed in both immune and other body cells.
Key Terms. Toll-like receptor: Toll-like receptors (TLRs) are a class of proteins that play a key role in the innate immune system as well as the digestive system.They are single, membrane-spanning, non-catalytic receptors that recognize structurally conserved molecules derived from microbes.
Innate immunity is the first defense system against invading pathogens. Toll-like receptors (TLRs) are well-defined pattern recognition receptors responsible for pathogen recognition and induction of innate immune responses. ... Xu D, Liew FY.

The Toll family of receptors comprises numerous related proteins implicated in the development and defense of plants and animals. Toll was first discovered in Drosophila melanogaster as a gene that controlled the dorsal-ventral axis of the developing embryo. Elements of its molecular structure; the extracellular leucine-rich repeat domain (LRR), short cysteine rich patches, a transmembrane ...
This review article summarizes the mechanisms and consequences of TLR-mediated signal transduction, which are central to innate immunity and host defense. It covers topics such as microbial detection, signal amplification, protein trafficking, and adaptive immunity, with a focus on themes that apply to other immune signaling pathways.

Toll-like receptors (TLRs) are an evolutionarily conserved family in the innate immune system and are the first line of host defense against microbial pathogens by recognizing pathogen-associated molecular patterns (PAMPs). TLRs, categorized into cell surface and endosomal subfamilies, recognize diverse PAMPs, and structural elucidation of TLRs ...
These functions heavily depend on pattern-recognition receptors (PRRs). 1 Among PRRs, a group of transmembrane proteins, Toll-like receptors (TLRs), are featured by their potent immunoadjuvant ability to activate antigen-presenting cells (APCs). 2, 3 TLRs include 10 (TLRs 1-10) and 12 (TLRs 1-9 and 11-13) family members in human subjects and ...
Toll-like receptors (TLRs) are cell surface and intracellular molecules on eukaryotic cells that detect and respond to microbial antigens. They derive their name from homology to the Drosophila Toll molecule, an important component of dorsal-ventral patterning and antifungal defense . TLRs are part of the innate immune system, which is a ...
This review attempts to cover the implication of the toll-like receptors (TLRs) in controlling immune functions with emphasis on their significance, function, regulation and expression patterns. The tripartite TLRs are type I integral transmembrane receptors that are involved in recognition and conveying of pathogens to the immune system.
Toll-like Receptors Function TLR signaling can induce a variety of functions in cells, which are dependent on the specific receptor, cell type, and other co-stimulatory signals involved. TLRs can stimulate expression of pro-inflammatory cytokines, proliferation and survival mechanisms, and facilitate communication between innate and adaptive ...
What are toll like receptors. Toll-like receptors are members of the pattern-recognition receptors family and play a key role in the innate immune system in the activation of innate immune cells including monocytes, macrophages and dendritic cells (DCs) 1.Macrophage activation by toll like receptors is pivotal in the initiation of the rapid expression of pro-inflammatory cytokines tumor ...
2. Toll-Like Receptors (TLRs) Toll-like receptors (TLRs) are evolutionarily conserved receptors belonging to the family of pattern recognition receptors (PRRs) which play a vital role in immune responses especially pathogen recognition by the extracellular matrix [18, 29 – 31].
Toll‐like receptors (TLRs) are pattern‐recognition receptors of the innate immune system that are activated when conserved molecular signatures on microbial or host molecules [pathogen‐ and danger‐associated molecular patterns (PAMPs and DAMPs, respectively)] are detected. 1 Mammalian TLRs were named due to their similarity to the Toll ...

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] In humans, TLR1 is encoded by the TLR1 gene, which is located on chromosome 4.
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 Receptors Function. TLR signaling can induce a variety of functions in cells, which are dependent on the specific receptor, cell type, and other co-stimulatory signals involved.
