Francisella tularensis is a virulent Gram-negative intracellular pathogen. To address the signaling routes involved in the response of host cells to LPS from F. tularensis live vaccine strain (LVS), experiments were performed in transiently transfected 293 cells. Induction of kappaB-driven transcriptional activity by 2.5 mug ml(-1) F. tularensis LPS(More)
AIMS Vascular inflammation is a major atherogenic factor and Toll-like receptor (TLR) 2 ligands, including bacterial and serum lipoproteins, seem to be involved in atherogenesis. On this basis, we analysed the effect of lipoproteins and different lipid components on TLR2-dependent signalling. METHODS AND RESULTS In TLR2-transfected human embryonic kidney(More)
The transport properties of Al/SRO/Si MOS-like structures were studied. A staircase behavior in the current versus voltage curves was observed at room temperature. This staircase behavior is ascribed to the Columbic blockade effect in the Si nano-dots embedded in the silicon oxide. The structure can be equivalent to a 2D multi-tunneling junction array,(More)
