Physiologically, lipopolysaccharide (LPS) is present in the bloodstream and can be bound to several proteins for its transport (i.e.) LPS binding protein (LBP) and plasma lipoproteins). LPS receptors CD14 and TLR-4 are constitutively expressed in the Central Nervous System (CNS). To our knowle...
Blocking LPS biosynthesis prior to the addition of an L-glycero-D-manno-heptose (Hep) residue results in increased bacterial sensitivity to hydrophobic antibiotics and phagocytosis by macrophages; thus, HepI is considered an excellent target for inhibitor development. In our efforts to determine the ...
1, LPS caused morphologic changes in the microglia. The cells became enlarged with a flattened Chemical reagents Lipopolysaccharide from Escherichia coli, serotype 026:B6, was purchased from Sigma-Aldrich Chemical Company (St. Louis, MO, USA). Other reagents used in this study were of analytical...
Lipopolysaccharide (LPS) as an important inflammatory mediator activates the innate/adaptive immune system. The existence of LPS in pancreatic ductal adenocarcinoma (PDAC) has been reported, however, its biological function in PDAC remains unclear. Here,
Lipopolysaccharide (LPS) dose response and time studies Male CD-1 mice aged 6–10 weeks were weighed and given an intraperitoneal (IP) injection of 0.03, 0.3, or 3 mg/kg LPS fromSalmonella typhimurium(Sigma Aldrich, St. Louis, MO, USA) dissolved in sterile normal saline. Mice were reweigh...
THP1 cells stimulated with LPS were harvested after 48 h for the nuclear protein extraction with a kit (CelLyticTMNuCLEARTM Extraction, Sigma-Aldrich). According to the manufacturer’s instructions, cells were allowed to swell with hypotonic buffer. Once disrupted, the cytoplasmic fraction was remov...
Materials and Methods Reagents. Lipopolysaccharide (LPS) was obtained from Sigma Aldrich (#L4524). Streptozotocin was also from Sigma Aldrich (#S0130). In situ hybridization. Paraffin-embedded block and section (6 μm) of mouse embryonic day 18.5 (E18.5) for in situ hybridization ...
Systemic lipopolysaccharide (LPS) is implicated in increasing mortality in patients with alcoholic hepatitis but the underlying mechanisms are not well characterised. The objective of this study was to characterise neutrophil function, LPS and cytokine concentrations within the splanchnic circulation of alcoho...
