CA150 expression delays striatal cell death in overexpression and knock-in conditions for mutant huntingtin neurotoxicity

Patrick Aebischer, Nicole Déglon, Diana Zala

Transcriptional dysregulation caused by expanded polyglutamines (polyGlns) in huntingtin (htt) may be central to cell-autonomous mechanisms for neuronal cell death in Huntington's disease (HD) pathogenesis. We hypothesized that these mechanisms may involve ...

Lentiviral-mediated delivery of mutant huntingtin in the striatum of rats induces a selective neuropathology modulated by polyglutamine repeat size, huntingtin expression levels, and protein length

Patrick Aebischer, Nicole Déglon, Diana Zala

A new strategy based on lentiviral-mediated delivery of mutant huntingtin (htt) was used to create a genetic model of Huntington's disease (HD) in rats and to assess the relative contribution of polyglutamine (CAG) repeat size, htt expression levels, and p ...

Long-term lentiviral-mediated expression of ciliary neurotrophic factor in the striatum of Huntington's disease transgenic mice

Patrick Aebischer, Nicole Déglon, Jean-Charles Bensadoun, Diana Zala

Ciliary neurotrophic factor (CNTF) has been shown to prevent behavioral deficits and striatal degeneration in neurotoxic models of Huntington's disease (HD), but its effect in a genetic model has not been evaluated. Lentiviral vectors expressing the human ...

Lentiviral-mediated gene transfer to model triplet repeat disorders

Patrick Aebischer, Nicole Déglon, Diana Zala

This chapter describes the potential use of viral-mediated gene transfer in the central nervous system as a new strategy in developing animal models of neurodegenerative diseases. To illustrate the approach, procedures for the production of lentiviral vect ...

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

Patrick Aebischer, Nicole Déglon, Diana Zala, Valérie Gafner

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 ...

Huntington's disease modeling and treatment : from primary neuronal cultures to rodents

Diana Zala

Huntington's disease (HD) is a mid-life-onset neurodegenerative disorder characterized by involuntary movements, personality changes and dementia. It progresses to death within 10-20 years after onset. There is currently no cure to treat this fatal disease ...

Neuroprotective effect of a CNTF-expressing lentiviral vector in the quinolinic acid rat model of Huntington's disease

Patrick Aebischer, Nicole Déglon, Diana Zala

Neurodegenerative diseases represent promising targets for gene therapy approaches provided effective transfer vectors. In the present study, we evaluated the effectiveness of LacZ-expressing lentiviral vectors with two different internal promoters, the mo ...

Dysregulation of gene expression in primary neuron models of Huntington's disease shows that polyglutamine-related effects on the striatal transcriptome may not be dependent on brain circuitry

Patrick Aebischer, Nicole Déglon, Diana Zala, Valérie Gafner

Gene expression changes are a hallmark of the neuropathology of Huntington's disease (HD), but the exact molecular mechanisms of this effect remain uncertain. Here, we report that in vitro models of disease comprised of primary striatal neurons expressing ...
