Description générale

Lipopolysaccharide (LPS) is the pyrogenic element arising from enterobacteria such as Escherichia coli and Salmonella enterica. It is an amphiphilic component containing polysaccharides and lipoidic material. LPS is present in the outer membrane of the cell wall of almost all Gram-negative bacteria.
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).

Application

Lipopolysaccharides from Salmonella enterica serotype minnesota has been used:
  • as a toll-like receptors (TLR ) agonist to induce tumor necrosis factor (TNF) α production in cereblon and Rabex-5 deficient mice in vivo,
  • to study its effect on prostaglandin-E Synthase (PTGES) protein expression in monocyte-derived macrophages
  • as a positive control for the maturation of monocyte-derived dendritic cells (MoDCs) to assess secretion of interleukin-10 and interferon (IFN)-γ
  • as a supplement in Roswell park memorial institute (RPMI)media for culturing splenic B cells
  • as a toll-like receptor 4 ligand to study its effect on the expression of the proallergic cytokines thymic stromal lymphopoietin (TSLP) and interleukin 33 (IL33) in H292 cells (pulmonary mucoepidermoid carcinoma cells)

Actions biochimiques/physiologiques

Lipopolysaccharide (LPS) forms a permeability barrier around the cell surface to restrict the entry of toxic molecules such as antibiotics and bile salts. Owing to their external location, this endotoxin also plays a vital role in host-bacterium interactions by regulating host immune response. LPS is a microbe-associated molecular pattern (MAMP) that serves as a potent agonist for toll-like receptor 4 (TLR4)-MD2-CD14 receptor complex.

SF3B1 is recurrently mutated in chronic lymphocytic leukemia (CLL), but its role in the pathogenesis of CLL remains elusive. Here, we show that conditional expression of Sf3b1-K700E mutation in mouse B cells disrupts pre-mRNA splicing, alters cell development, and induces
