Escherichia coli Braun Lipoprotein (BLP) exhibits endotoxemia – like pathology in Swiss albino mice
The endotoxin lipopolysaccharide (LPS) promotes sepsis, but bacterial peptides also promote inflammation leading to sepsis. We found, intraperitoneal administration of live or heat inactivated E. coli JE5505 lacking the abundant outer membrane protein, Braun lipoprotein (BLP), was less toxic than E. coli DH5α possessing BLP in Swiss albino mice. Injection of BLP free of LPS purified from E. col...
متن کاملEscherichia coli Braun lipoprotein induces a lipopolysaccharide-like endotoxic response from primary human endothelial cells.
All bacteria contain proteins in which their amino-terminal cysteine residue is modified with N-acyl S-diacylglycerol functions, and peptides and proteins bearing this modification are immunomodulatory. The major outer membrane lipoprotein of Escherichia coli, the Braun lipoprotein (BLP), is the prototypical triacylated cysteinyl-modified protein. We find it is as active as LPS in stimulating h...
متن کاملBrucella outer membrane lipoprotein shares antigenic determinants with Escherichia coli Braun lipoprotein and is exposed on the cell surface.
In an enzyme-linked immunosorbent assay (ELISA), purified Brucella abortus and Escherichia coli peptidoglycan-linked lipoproteins gave a strong cross-reaction with sera from rabbits hyperimmunized with the heterologous lipoprotein. When smooth E. coli cells were used as ELISA antigens, the immunological cross-reaction was not observed unless the cells were treated to remove lipopolysaccharide a...
متن کاملRadioprotective Efficacy of Lutein in Ameliorating Electron Beam Radiation-induced Oxidative Injury in Swiss Albino Mice
Background: Lutein, a carotenoid compound, has previously been studied for its antioxidant and medicinal properties as well as the moderate protection it confers against gamma radiation. This study aimed at evaluating the effects of lutein against radiation-induced hematological and biochemical changes in mice.Methods: The optimized dose of the compound was orally administered for 15 days, and ...
متن کاملProtective effect of Hypericum hookerianum in reversing haloperidol induced schizophrenia-like behaviors in Swiss albino mice
A major mental disorder that affects young people, schizophrenia ( Greek “split mind”) is characterized by a variety of symptoms including but not limited to , loss of contact with reality, bizarre behaviour, disorganized thinking, speech, decreased emotional expressiveness ,loss of contact with reality and society and long-lasting, not completely successful treatment. Anti-psychotics are the d...
