Capsular Polysaccharide Restrains Type VI Secretion in Acinetobacter baumannii

Melanie Blokesch, Loriane Bader, Mary-Claude Croisier-Coeytaux, Nicolas Olmo Flaugnatti

The type VI secretion system (T6SS) is a sophisticated, contact-dependent nanomachine involved in interbacterial competition. To function effectively, the T6SS must penetrate the membranes of both attacker and target bacteria. Structures associated with th ...

Development of multiplexed single-molecule imaging techniques to study chromatin invasion dynamics of chromatin effector proteins

Kristina Makasheva

DNA-binding proteins physically interact with the DNA and directly affect genomic functions. The eukaryotic genome is compacted into chromatin, limiting the DNA access to nuclear factors. In this Ph.D. thesis, I explored the dynamic mechanisms, that allow ...

Correlative light and volume electron microscopy to study brain development

Graham Knott

Recent advances in volume electron microscopy (EM) have been driving our thorough understanding of the brain architecture. Volume EM becomes increasingly powerful when cells and their subcellular structures that are imaged in light microscopy are correlate ...

An optimized high throughput platform, from genetic transformation to fermentation, to screen for secreted laccases in Aspergillus niger

Laure Marie Colette Leynaud-Kieffer Curran

Many challenges are faced in the conversion of biomass into advanced biofuels, one of which is finding the correct organism for the job. The filamentous fungus Aspergillus niger has been chosen as a biocatalyst for cellulose, hemicellulose, and lignin degr ...

Engineering Agrobacterium tumefaciens Adhesion to Target Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jeremy Pak Hei Wong, Alix Kim Lan Pham

Agrobacterium tumefaciens is a plant pathogen commonly repurposed for genetic modification of crops. Despite its versatility, it remains inefficient at transferring DNA to many hosts, including to animal cells. Like many pathogens, physical contact between ...

Mapping and Analysis of the Complexity of Lipid Metabolism for Applications in Health and Sustainability

Vassily Hatzimanikatis, Sofia Tsouka

Metabolism is a network of biotransformations that sustain life in cells. Over the past decades, metabolism has been studied in multiple contexts, ranging from medicine to industrial manufacturing. In particular, lipid metabolism has been linked to various ...

Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii

Bruno Lemaitre, Samuel Rommelaere, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...
