The contribution of the host stress response to the pathogenesis of Pseudomonas entomophila in the Drosophila intestine

Recently, several studies done in Drosophila have revealed that efficient and rapid recovery from bacterial infection in the gut is possible only when bacterial clearance by the immune system is coordinated with repair through renewal of the epithelium dam ...

Physicochemical Characterization of Phosphopeptide/Titanium Dioxide Interactions Employing the Quartz Crystal Microbalance Technique

Ulf Anders Hagfeldt, Anna Eriksson

The rapidly growing field of phosphoproteomics has led to a strong demand for procedures enabling fast and reliable isolation and enrichment of phosphorylated proteins and peptides. During the past decade, several novel phosphopeptide enrichment methods ba ...

Innovative semi-transparent nanocomposite films presenting photo-switchable behavior and leading to a reduction of the risk of infection under sunlight

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

Novel sputtered polyethylene-TiO2 (PE-TiO2) thin films induce fast bacterial inactivation with concomitant photo-switchable hydrophobic to hydrophilic transition under light. RF-plasma pretreatments allowed an increased TiO2 loading on PE, favorably affect ...

Improving binding affinity and stability of peptide ligands by substituting glycines with D-amino acids

Christian Heinis, Petr Leiman, David Gfeller, Shiyu Chen, Sergii Buth, Olivier Michielin

Improving the binding affinity and/or stability of peptide ligands often requires testing of large numbers of variants to identify beneficial mutations. Herein we propose a type of mutation that promises a high success rate. In a bicyclic peptide inhibitor ...

Testing the diffusing boundary model for the helix-coil transition in peptides

Beat Fierz

The dynamics of peptide α-helices have been studied extensively for many years, and the kinetic mechanism of the helix-coil dynamics has been discussed controversially. Recent experimental results have suggested that equilibrium helix-coil dynamics are gov ...

Site-Specific PEGylation of HR2 Peptides: Effects of PEG Conjugation Position and Chain Length on HIV-1 Membrane Fusion Inhibition and Proteolytic Degradation

Harm-Anton Klok, Maarten Danial

Peptides derived from the HR1 or HR2 regions of the HIV-1 envelope glycoprotein gp41 have been shown to be effective inhibitors to prevent virus-host cell membrane fusion. These peptide drugs, however, suffer from relatively short plasma half-lives and are ...

Induction of type I IFNs by intracellular DNA-sensing pathways

Andrea Ablasser

A successful antimicrobial immune response involves the coordinate action of cells and soluble factors, with the cytokine family of type I interferons (IFNs) having a central role. Type I IFNs are not only crucial in conferring immediate antimicrobial, mos ...

Materials science: Cell environments programmed with light

Matthias Lütolf

A combination of two light-induced reactions has been used to attach peptides to a polymeric gel, and then to detach them from it. This feat opens up opportunities for studying the effects of signalling molecules on cell behaviour in vitro. ...

Differential peptide binding to CD40 evokes counteractive responses

Giovanni Dietler, Sandor Kasas, Charles Roduit, Livan Bladimir Alonso Sarduy, Bhaskar Saha

The antigen-presenting cell-expressed CD40 is implied in the regulation of counteractive immune responses such as induction of pro-inflammatory and anti-inflammatory cytokines interleukin (IL)-12 and IL-10, respectively. The mechanism of this duality in CD ...

Phage Selection of Bicyclic Peptide Ligands and Development of a New Peptide Cyclisation Method

Jeremy Touati

Bicyclic peptides binding to targets of interest can be isolated from combinatorial libraries using a phage display-based approach. In a first project of this thesis, we aimed at generating bicyclic peptide inhibitors of matrix metalloproteinases (MMPs), a ...
