Általános leírás

Lipopolysaccharides (LPSs) are characteristic components of the cell wall of Gram-negative bacteria. LPS and its lipid A moiety stimulate cells of the innate immune system by the Toll-like receptor 4 (TLR4), a member of the Toll-like receptor protein family, which recognizes common pathogen-associated molecular-patterns (PAMPs).
This product is extracted from Salmonella Minnesota and purified by gel filtration. The source strain is ATCC 9700. Mechanisms of complement activation by LPS of both rough and smooth strains of Salmonella Minnesota were studied by immunoassay of the activation products.

Alkalmazás


  • TRPV4 is not the molecular sensor for bacterial lipopolysaccharides-induced calcium signaling: This study explores the signaling pathways activated by lipopolysaccharides from Salmonella enterica serotype Minnesota, demonstrating that TRPV4 is not involved, advancing understanding of immune responses to bacterial endotoxins (Wang et al., 2023).

Biokémiai/fiziológiai hatások

Lipopolysaccharides (LPS) are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell surface. They contribute to the integrity of the outer membrane, and protect the cell against the action of bile salts and lipophilic antibiotics.

Elkészítési megjegyzés

The product is soluble in water (5 mg/ml) or cell culture medium (1 mg/ml) yielding a hazy, faint yellow solution. A more concentrated, though still hazy, solution (20 mg/ml) has been achieved in aqueous saline after vortexing and warming to 70-80 oC. Lipopolysaccharides are molecules that form micelles in every solvent. Hazy solutions are observed in water and phosphate buffered saline. Organic solvents do not give clearer solutions. Methanol yields a turbid suspension with floaters, while water yields a homogeneously hazy solution.

Broad-spectrum inhibitors of histone deacetylases (HDACs) constrain Toll-like receptor (TLR)-inducible production of key proinflammatory mediators. Here we investigated HDAC-dependent inflammatory responses in mouse macrophages. Of the classical Hdacs, Hdac7 was expressed at elevated levels in inflammatory macrophages (thioglycollate-elicited peritoneal macrophages)

Macrophage pre-treatment with bacterial lipopolysaccharide (LPS) boosts subsequent activation of the NLRP3 inflammasome, which controls caspase-1-dependent pro-inflammatory cytokine maturation. Previous work has attributed this phenomenon (known as LPS 'priming') to LPS-dependent induction of NLRP3 expression. Whilst this plays a role

Gram-negative bacterial infections are accompanied by inflammation and somatic or visceral pain. These symptoms are generally attributed to sensitization of nociceptors by inflammatory mediators released by immune cells. Nociceptor sensitization during inflammation occurs through activation of the Toll-like receptor 4

Microglia are resident macrophage-like APCs of the CNS. To avoid escalation of inflammatory processes and bystander damage within the CNS, microglia-driven inflammatory responses need to be tightly regulated and both spatially and temporally restricted.
