Force-induced globule-coil transition in laminin binding protein and its role for viral-cell membrane fusion

Giovanni Dietler, Fabrizio Benedetti, Andrey Mikhaylov, Tatyana Karakouz, Denis Korneev

The specific interactions of the pairs laminin binding protein (LBP)-purified tick-borne encephalitis viral surface protein E and certain recombinant fragments of this protein, as well as West Nile viral surface protein E and certain recombinant fragments ...

Nonstructural protein 3-4A: the Swiss army knife of hepatitis C virus

Etienne Meylan

Hepatitis C virus (HCV) nonstructural protein 3-4A (NS3-4A) is a complex composed of NS3 and its cofactor NS4A. It harbours serine protease as well as NTPase/RNA helicase activities and is essential for viral polyprotein processing, RNA replication and vir ...

Characterization of glycoprotein E C-End of West Nile virus and evaluation of its interaction force with alpha V beta 3 integrin as putative cellular receptor

Giovanni Dietler

Recombinant polypeptide containing the 260-466 amino acid sequence of West Nile virus (WNV) strain LEIV-Vlg99-27889-human glycoprotein E (gpE, E260-466) was constructed. Immunochemical similarity between the E260-466 and gpE of WNV was proven by enzyme imm ...

Application of broad-spectrum resequencing microarray for genotyping rhabdoviruses

Stewart Cole, Iain Old

The rapid and accurate identification of pathogens is critical in the control of infectious disease. To this end, we analyzed the capacity for viral detection and identification of a newly described high-density resequencing microarray (RMA), termed Pathog ...

Immunochernical and single molecule force spectroscopy studies of specific interaction between the laminin binding protein and the West Nile virus surface glycoprotein E domain II

Giovanni Dietler, Mélanie Favre

ELISA and Western blot immunochemical data attest an effective and highly specific interaction of the surface glycoprotein E domain II (DII) of the tick born encephalitis and Dengue viruses with the laminin binding protein (LBP). Based on a highly conserva ...

Physical properties and interactions of biomolecules

Mélanie Favre

The aim of this thesis was to explore the statistical physics and the mechanical properties of individual biomolecules, to study their interactions, and to develop new techniques based on atomic force microscopy (AFM). First, we exploit the high resolution ...

Relaxation processes of point defects in vitreous silica from femtosecond to nanoseconds

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Wojciech Gawelda, Erwin Portuondo Campa, Andrea Callegari

The authors studied ultrafast relaxation of localized excited states at Ge-related O deficient centers in SiO2 using femtosecond transient-absorption spectroscopy. The relaxation dynamics exhibits a biexponential decay, which the authors ascribe to the dep ...

The antiviral adaptor proteins Cardif and Trif are processed and inactivated by caspases

Etienne Meylan

The outcome of a viral infection depends on the interplay between the host's capacity to trigger potent antiviral responses and viral mechanisms that counteract them. Although Toll-like receptor (TLR)-3, which recognizes virally derived double-stranded (ds ...

In vivo imaging enters parasitology

In vivo infection routes of parasites have remained something of a "black box", in which only snapshot views of fixed tissues are available. Clearly, there exists a strong need for imaging approaches to visualise living parasites within intact organs and a ...

Displaying Epidermal Growth Factor on Spleen Necrosis Virus-Derived Targeting Vectors

Christoph Merten

Targeted gene transfer into human cells has previously been achieved with spleen necrosis virus (SNV)-derived vector particles harboring envelope (Env) proteins which carry single chain Fv (scFv) domains derived from antibodies. Such cell targeting vectors ...
