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.

    Pamidronate disodium
    Inhibitor ≥98.0%
    Pamidronate disodium (CGP 23339A), the second-generation nitrogen-containing bisphosphonate, is an inhibitor of bone loss. Pamidronate disodium significantly inhibits subchondral bone loss in early osteoarthritis by upregulating the expression of osteoprotegerin in cartilage and subchondral bone, and inhibiting the expression of RANKL and MMP-9 in both tissues, as well as TLR-4 in cartilage, thereby alleviating cartilage degeneration. Additionally, Pamidronate disodium can inhibit the signaling of Wnt and β-catenin, and is applicable for research on osteoporosis and osteosarcoma.
