The combined impact of persistent infections and human genetic variation on C-reactive protein levels

Jacques Fellay, Olivier Noël Marie Naret, Flavia Aurelia Shoko Hodel, Clara Bonnet

Multiple human pathogens establish chronic, sometimes life-long infections. Even if they are often latent, these infections can trigger some degree of local or systemic immune response, resulting in chronic low-grade inflammation. There remains an incomple ...

Sirt6 deletion in bone marrow-derived cells increases atherosclerosis - Central role of macrophage scavenger receptor 1

Johan Auwerx, Matthias Alexander Sokrates Stein, Julien Weber, Tasneem Arsiwala

Aims: Sirtuin 6 (Sirt6) is a NAD(+)-dependent deacetylase that plays a key role in DNA repair, inflammation and lipid regulation. Sirt6-null mice show severe metabolic defects and accelerated aging. Macrophage-foam cell formation via scavenger receptors is ...

Intracellular bacteria engage a STING-TBK1-MVB12b pathway to enable paracrine cGAS-STING signalling

Andrea Ablasser, Thomas Charles Henry Rossi, Bing Zhang, Alix Martin, Ensieh Farahani

The innate immune system is crucial for eventual control of infections, but may also contribute to pathology. Listeria monocytogenes is an intracellular Gram-positive bacteria and a major cause of food-borne disease. However, important knowledge on the int ...

A microfluidic cell-trapping device to study dynamic host-microbe interactions at the single-cell level

John McKinney, Matthieu Jean-Hubert Delincé, Chiara Toniolo

Single-cell imaging of host-microbe interactions over time is impeded by cellular motility because the cells under scrutiny tend to migrate out of the imaging field. To overcome this technical challenge, we developed a microfluidic platform for imaging hun ...

Atomic Force Microscopy of Biological Systems: Quantitative Imaging and Nanomotion Detection

Petar Stupar

The core of this thesis is the application of different modalities of atomic force microscopy to study living systems. After a brief introduction, quantitative imaging state of the art is presented and the applications for mammalian, plant, bacterial, and ...

Protein engineering approaches for direct antigen targeting in CD8+ T cell inducing vaccines

Vasiliki Panagiotou

Effective vaccine design and public vaccination programs have led to the eradication of several diseases and protected millions of people from deadly infections. However, intracellular infections remain a challenge and their eradication requires the activa ...

Cell-wall deficient L. monocytogenes L-forms feature abrogated pathogenicity

Nicola Harris

Stable L-forms are cell wall-deficient bacteria which are able to multiply and propagate indefinitely, despite the absence of a rigid peptidoglycan cell wall. We investigated whether L-forms of the intracellular pathogen L. monocytogenes possibly retain pa ...

A Role for Septins in the Interaction between the Listeria monocytogenes Invasion Protein InlB and the Met Receptor

Sandor Kasas, Charles Roduit

Septins are conserved GTPases that form filaments and are required for cell division. During interphase, septin filaments associate with cellular membrane and cytoskeleton networks, yet the functional significance of these associations have, to our knowled ...

Cellular Responses to Bacterial Pore-Forming Toxins

Rodrigo Manuel Gonzalez

Pore-forming toxins (PFTs) represent the largest class of bacterial protein toxins and constitute major virulence factors produced by pathogenic bacteria during infection. Pore formation appears to be an ancient form of attack, which is also found in hydro ...
