Cell surface lipopolysaccharides of different rhizobia

Different NK Cell Surface Phenotypes

Role of Cell Surface Lipopolysaccharides in Escherichia coli K12 adhesion and transport.

The influence of bacterial surface lipopolysaccharides (LPS) on cell transport and adhesion has been examined by use of three mutants of Escherichia coli K12 with well-characterized LPS of different lengths and molecular composition. Two experimental techniques, a packed-bed column and a radial stagnation point flow system, were employed to investigate bacterial adhesion kinetics onto quartz su...

Lipopolysaccharides in liver injury: molecular mechanisms of Kupffer cell activation.

Endogenous gut-derived bacterial lipopolysaccharides have been implicated as important cofactors in the pathogenesis of liver injury. However, the molecular mechanisms by which lipopolysaccharides exert their effect are not entirely clear. Recent studies have pointed to proinflammatory cytokines such as tumor necrosis factor-alpha as mediators of hepatocyte injury. Within the liver, Kupffer cel...

Bone cell attachment to dental implants of different surface characteristics.

Previous studies to compare the influence of surface characteristics of dental implants on cell behavior have used model systems to simulate the implant surface. In this study, bone cell interactions with smooth titanium, titanium dioxide-blasted, titanium plasma-sprayed, and hydroxyapatite plasma-sprayed implants, as manufactured for clinical use, were compared. Implants were exposed to neonat...
