The role of the NF-kappaB pathway in Amyotrophic lateral sclerosis pathogenesis

Emma Charlotta Källstig

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor disorder, which results in death within a few years of diagnosis. While the cause of most cases of ALS is unknown, 10% of cases are familial (fALS), and associated with mutations in one of ov ...

Viral Transfer and Inactivation through Zooplankton Trophic Interactions

Tamar Kohn, Virginie Bachmann, Xavier Fernandez Cassi, Margot Ninon Lauren Olive

Waterborne viruses are responsible for numerous diseases and are abundant in aquatic systems. Understanding the fate of viruses in natural systems has important implications for human health. This research quantifies the uptake of bacteriophage T4 and the ...

Patchy Amphiphilic Dendrimers Bind Adenovirus and Control Its Host Interactions and in Vivo Distribution

Francesco Stellacci, Weina Liu

The surface of proteins is heterogeneous with sophisticated but precise hydrophobic and hydrophilic patches, which is essential for their diverse biological functions. To emulate such distinct surface patterns on macromolecules, we used rigid spherical syn ...

Miniaturized single-cell analyses for biomedical applications

Loïc Arvind Roger Arm

Numerous diseases affecting living beings have as a cause a modification of gene expression resulting in anomalous expression of proteins in up- or down-regulated fashion, with altered functions or expression of proteins that are not present in the cell in ...

Natural competence for transformation

Melanie Blokesch

While most molecular biologists are familiar with the artificial transformation of bacteria in the context of laboratory cloning experiments, natural competence for transformation refers to a specific physiological state in which prokaryotes are able to ta ...

Recombinant protein production from stable mammalian cell lines and pools

David Hacker, Sowmya Balasubramanian

We highlight recent developments for the production of recombinant proteins from suspension-adapted mammalian cell lines. We discuss the generation of stable cell lines using transposons and lentivirus vectors (non-targeted transgene integration) and site- ...

A High-Throughput Microfluidic Platform for Mammalian Cell Transfection and Culturing

Sebastian Maerkl, Kristina Pan Woodruff

Mammalian synthetic biology could be augmented through the development of high-throughput microfluidic systems that integrate cellular transfection, culturing, and imaging. We created a microfluidic chip that cultures cells and implements 280 independent t ...

Improved biocompatibility of polyethylenimine (PEI) as a gene carrier by conjugating urocanic acid: In vitro and in vivo

Jeffrey Alan Hubbell, Irina Krier

Polyethylenimine (PEI) is a promising gene carrier among polymeric vectors because of its high transfection efficiency, buffering capacity, which is responsible for its escape from endosomes, facility of modification, reasonable price and wide range of mol ...

Study of transposon-mediated cell pool and cell line generation in CHO cells

Sowmya Balasubramanian

The goal of this thesis was to evaluate the use of artificial transposon systems for the generation of recombinant cell pools and cell lines with Chinese hamster ovary (CHO) cells as the production host. Transposons are naturally occurring genetic elements ...

Genetic engineering of cell lines using lentiviral vectors to achieve antibody secretion following encapsulated implantation

Patrick Aebischer, Bernard Schneider, Marc Moniatte, Aurélien Lathuilière

The controlled delivery of antibodies by immunoisolated bioimplants containing genetically engineered cells is an attractive and safe approach for chronic treatments. To reach therapeutic antibody levels there is a need to generate renewable cell lines, wh ...

TransFLP - A Method to Genetically Modify Vibrio cholerae Based on Natural Transformation and FLP-recombination

Melanie Blokesch

Several methods are available to manipulate bacterial chromosomes(1-3). Most of these protocols rely on the insertion of conditionally replicative plasmids (e.g. harboring pir-dependent or temperature-sensitive replicons(1,2)). These plasmids are integrate ...
