Toll-like Receptor (TLR)

Toll-like receptors (TLRs) are a class of proteins that play a key role in the innate immune system. They are single, membrane-spanning, non-catalytic receptors usually expressed in sentinel cells such as macrophages and dendritic cells, that recognize structurally conserved molecules derived from microbes. Once these microbes have breached physical barriers such as the skin or intestinal tract mucosa, they are recognized by TLRs, which activate immune cell responses. The TLRs include TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR10, TLR11, TLR12, and TLR13. Toll-Like Receptors (TLRs) play a critical role in the early innate immune response to invading pathogens by sensing microorganism and are involved in sensing endogenous danger signals. TLRs are evolutionarily conserved receptors are homologues of the Drosophila Toll protein, discovered to be important for defense against microbial infection. TLRs recognize highly conserved structural motifs known as pathogen-associated microbial patterns (PAMPs), which are exclusively expressed by microbial pathogens.

    Lipopolysaccharides, from S. marcescens
    Activator
    Lipopolysaccharides, from S. marcescens (Serratia marcescens) are lipopolysaccharide endotoxins and TLR-4 activators derived from Serratia marcescens, classified as S-type LPS, which can activate pathogen-associated molecular patterns (PAMP) of the immune system and induce cellular secretion of migrasomes. Lipopolysaccharides, from S. marcescens exhibit a typical three-part structure: O-antigen (O-antigen), core oligosaccharide (core oligosaccharide), and lipid A (Lipid A). Lipopolysaccharides, from S. marcescens induce NF-κB activation in mouse cells via Toll-like receptor (TLR4)/MD-2. The lipopolysaccharides of S. marcescens can induce apoptosis in host immune cells, thereby suppressing the host's innate immunity.
    It is recommended to prepare a stock solution of ≥2 mg/mL and ensure that it is fully mixed and dissolved. Due to the adsorption characteristics of LPS, low adsorption centrifuge tubes should be used for aliquoting and storage.

    Activator
    Lipopolysaccharides from P. aeruginosa (Pseudomonas aeruginosa) 10 are lipopolysaccharide endotoxins and TLR4 activators derived from Pseudomonas aeruginosa 10, and are classified as S-type LPS. Lipopolysaccharides from P. aeruginosa 10 exhibit a typical three-part structure: O-antigen, core oligosaccharide, and lipid A. The lipopolysaccharides of P. aeruginosa 10 have a fatty acid composition distinct from common enterobacteria, an exceptionally high degree of phosphorylation (triphosphate residues have been detected), and a unique outer region of the core oligosaccharide. Additionally, their O-specific side chains are typically rich in novel aminosugars. Lipopolysaccharides from P. aeruginosa 10 demonstrate susceptibility to viruses, with the level of susceptibility determined by the content of high molecular weight polysaccharides in their composition. The absence of high molecular weight polysaccharides increases their sensitivity to bacteriophages.
    It is recommended to prepare a stock solution of ≥2 mg/mL and ensure that it is fully mixed and dissolved. Due to the adsorption characteristics of LPS, low adsorption centrifuge tubes should be used for aliquoting and storage.
