Lipopolysaccharide O-antigens—bacterial glycans made to measure

Journal of Biological Chemistry, 2020
Lipopolysaccharides are critical components of bacterial outer membranes. The more conserved lipid A part of the lipopolysaccharide molecule is a major element in the permeability barrier imposed by the outer membrane and offers a pathogen-associated ...

Phosphodiesterase 4B is essential for lipopolysaccharide-induced CC chemokine ligand 3 production in mouse macrophages

Journal of Medical Sciences, 2015
Background: Phosphodiesterase 4 (PDE4) inhibitors negatively modulate many inflammatory responses, and some of these pharmacological effects are mediated by inhibition of PDE4B in inflammatory cells.

Localization of lipopolysaccharide from Escherichia Coli into human atherosclerotic plaque [PDF]

, 2018
Experimental studies showed that gut-derived lipopolysaccharide (LPS) is pro-atherogenic, however, its relationship with human atherosclerosis is still to be defined.

Antioxidant mitoquinone ameliorates EtOH-LPS induced lung injury by inhibiting mitophagy and NLRP3 inflammasome activation

Frontiers in Immunology, 2022
Chronic ethanol abuse is a systemic disorder and a risk factor for acute respiratory distress syndrome (ARDS) and chronic obstructive pulmonary disease (COPD). However, the mechanisms involved are unknown.

Lipopolysaccharides in diazotrophic bacteria [PDF]

Frontiers in Cellular and Infection Microbiology, 2014
Biological nitrogen fixation (BNF) is a process in which the atmospheric nitrogen (N2) is transformed into ammonia (NH3) by a select group of nitrogen-fixing organisms, or diazotrophic bacteria. In order to furnish the biologically useful nitrogen to plants, these bacteria must be in constant molecular communication with their host plants.

Gut-Derived Serum Lipopolysaccharide is Associated With Enhanced Risk of Major Adverse Cardiovascular Events in Atrial Fibrillation: Effect of Adherence to Mediterranean Diet [PDF]

, 2017
Gut microbiota is emerging as a novel risk factor for atherothrombosis, but the predictive role of gut-derived lipopolysaccharide (LPS) is unknown. We analyzed (1) the association between LPS and major adverse cardiovascular events (MACE) in atrial ...

The atypical lipopolysaccharide ofFrancisella [PDF]

Carbohydrate Research, 2013
Bacterial lipopolysaccharides (LPSs) are ubiquitous molecules that are prominent components of the outer membranes of most gram-negative bacteria. Genetic and structural characterizations of Francisella LPS have revealed substantial differences when compared to more commonly studied LPSs of the Enterobacteriaceae. This review discusses both the general

MD-2, a Molecule that Confers Lipopolysaccharide Responsiveness on Toll-like Receptor 4

Journal of Experimental Medicine, 1999
Toll-like receptor 4 (TLR4) is a mammalian homologue of Drosophila Toll, a leucine-rich repeat molecule that can trigger innate responses against pathogens.
