A Baseline Cellular Antiviral State Is Maintained by cGAS and Its Most Frequent Naturally Occurring Variant rs610913

Jacques Fellay, Christian Axel Wandall Thorball, Shuting Xu

Upon recognition of aberrantly located DNA, the innate immune sensor cyclic GMP-AMP synthase (cGAS) activates stimulator of IFN genes (STING)/IFN regulatory factor (IRF)3-driven antiviral responses. In this study, we characterized the ability of a specific ...

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- ...

Lentiviral Vector-Mediated Gene Delivery for the Generation of Chinese Hamster Ovary Cell Lines with Improved Productivity and Stability

Agata Oberbek

Recombinant cell line generation by standard transfection techniques is a time-consuming and labor-intensive process often leading to an unpredictable outcome as transgene integration is a rare, random event. Consequently, the population of cells obtained ...

Generation of stable, high-producing cho cell lines by lentiviral vector-mediated gene transfer in serum-free suspension culture

Florian Maria Wurm, David Hacker, Agata Oberbek

Lentivirus-derived vectors (LVs) were studied for the generation of stable recombinant Chinese hamster ovary (CHO) cell lines. Stable pools and clones expressing the enhanced green fluorescent protein (eGFP) were selected via fluorescence-activated cell so ...

Functional analysis and structural modeling of human APOBEC3G reveal the role of evolutionarily conserved elements in the inhibition of human immunodeficiency virus type 1 infection and Alu transposition

Didier Trono, Priscilla Turelli, Olivier Michielin, Bastien Mangeat

Retroelements are important evolutionary forces but can be deleterious if left uncontrolled. Members of the human APOBEC3 family of cytidine deaminases can inhibit a wide range of endogenous, as well as exogenous, retroelements. These enzymes are structura ...

Studies on lentiviral-mediated transgenesis

Marc-Olivier Sauvain

Transgenic animals are essential research tools, whether to address basic biological questions or to develop preclinical models of human diseases. Their generation through the injection of naked plasmid DNA into the male pronucleus of a fertilized oocyte h ...

Studies on scaffold design for tissue engineering applications : contribution of synthetic, natural and recombinant materials

The aim of tissue engineering is to regenerate tissue for the purpose of repairing or replacing diseased or injured tissue. Therefore, cells that are able to proliferate are seeded on scaffolds that provide mechanical stability and direct the three-dimensi ...

Response of aged parkinsonian monkeys to in vivo gene transfer of GDNF

Patrick Aebischer, Romain Zufferey

This study assessed the potential for functional and anatomical recovery of the diseased aged primate nigrostriatal system, in response to trophic factor gene transfer. Aged rhesus monkeys received a single intracarotid infusion of MPTP, followed one week ...

Lentiviral vector-mediated genetic modification of human neural progenitor cells for ex vivo gene therapy

Patrick Aebischer, Bernard Schneider, Romain Zufferey

Human neural progenitor cells (hNPC) hold great potential as an ex vivo system for delivery of therapeutic proteins to the central nervous system. When cultured as aggregates, termed neurospheres, hNPC are capable of significant in vitro expansion. In the ...

The KRAB repressor domain can trigger de novo promoter methylation during mouse early embryogenesis

Didier Trono, Patrick Aebischer, Friedrich Beermann, Shuangqing Liao, Johan Jakobsson

The Krüppel-associated box (KRAB) domain is a transcriptional repression module responsible for the DNA binding-dependent gene silencing activity of hundreds of vertebrate zinc finger proteins. We previously exploited KRAB-mediated repression within the co ...

KRAB can repress lentivirus proviral transcription independently of integration site

Didier Trono, Isabelle Barde

The KRAB transcriptional repressor domain, commonly found in zinc finger proteins, acts by inducing the formation of heterochromatin. We previously exploited this property to achieve drug-regulated transgenesis and knock down by combining doxycycline-contr ...

Lentivirus-mediated expression of glutathione peroxidase: neuroprotection in murine models of Parkinson's disease

Patrick Aebischer, Jean-Charles Bensadoun, Nicole Déglon

Reactive oxygen species are considered to contribute to the pathogenesis of Parkinson's disease (PD). In order to study viral vector-mediated overexpression of the antioxidant enzyme glutathione peroxidase (GPX) as a potential neuroprotective approach in b ...

A versatile tool for conditional gene expression and knockdown

Didier Trono, Patrick Aebischer, Marc-Olivier Sauvain

Drug-inducible systems allowing the control of gene expression in mammalian cells are invaluable tools for genetic research, and could also fulfill essential roles in gene- and cell-based therapy. Currently available systems, however, often have limited in ...

Transgenic SOD1 mice as a model for developing amyotrophic lateral sclerosis therapies

Sandrine Guillot

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by a loss of motor neurons in the brain (brainstem and cortex) and the spinal cord that leads to a motor neurological symptomatology. Approximately 10% of ALS case ...

Progressive and selective striatal degeneration in primary neuronal cultures using lentiviral vector coding for a mutant huntingtin fragment

Patrick Aebischer, Valérie Gafner, Nicole Déglon, Diana Zala

A lentiviral vector expressing a mutant huntingtin protein (htt171-82Q) was used to generate a chronic model of Huntington's disease (HD) in rat primary striatal cultures. In this model, the majority of neurons expressed the transgene so that Western blot ...
