Preferential Enhancement of Sensory and Motor Axon Regeneration by Combining Extracellular Matrix Components with Neurotrophic Factors

After peripheral nerve injury, motor and sensory axons are able to regenerate but inaccuracy of target reinnervation leads to poor functional recovery. Extracellular matrix (ECM) components and neurotrophic factors (NTFs) exert their effect on different ne ...

Focal release of neurotrophic factors by biodegradable microspheres enhance motor and sensory axonal regeneration in vitro and in vivo

Silvestro Micera, Daniel Santos

Neurotrophic factors (NTFs) promote nerve regeneration and neuronal survival after peripheral nerve injury. However, drawbacks related with administration and bioactivity during long periods limit their therapeutic application. In this study, PLGA microsph ...

Astrocytes: New Targets for the Treatment of Neurodegenerative Diseases

Pierre Magistretti, Sylvain Eric Lengacher, Charles Léonard Finsterwald

The causes of neurodegenerative disorders are multiple, and for most of them a mechanistic understanding is still lacking. However, neurodegenerative diseases such as Alzheimer disease (AD), amyotrophic lateral sclerosis (ALS) and Parkinson disease (PD) al ...

Regulation of Neurotrophic Factors and Energy Metabolism by Antidepressants in Astrocytes

Pierre Magistretti, Jean-Luc Martin, Igor Allaman

There is growing evidence that astrocytes are involved in the neuropathology of major depression. In particular, decreases in glial cell density observed in the cerebral cortex of individuals with major depressive disorder are accompanied by a reduction of ...

Glycogen metabolism as a marker of astrocyte differentiation

Pierre Magistretti, Igor Allaman, Luc Pellerin

Glycogen is a hallmark of mature astrocytes, but its emergence during astrocytic differentiation is unclear. Differentiation of E14 mouse neurospheres into astrocytes was induced with fetal bovine serum (FBS), Leukemia Inhibitory Factor (LIF), or Ciliary N ...

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 gene therapy for Huntington's disease, using polymer-encapsulated cells engineered to secrete human ciliary neurotrophic factor: results of a phase I study

Patrick Aebischer, Nicole Déglon

Huntington's disease (HD) is a monogenic neurodegenerative disease that affects the efferent neurons of the striatum. The protracted evolution of the pathology over 15 to 20 years, after clinical onset in adulthood, underscores the potential of therapeutic ...

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

Patrick Aebischer, Jean-Charles Bensadoun, Nicole Déglon, 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 nigral delivery of GDNF does not prevent neurodegeneration in a genetic rat model of Parkinson's disease

Patrick Aebischer, Nicole Déglon, Christophe Lo Bianco

Viral delivery of glial cell line-derived neurotrophic factor (GDNF) currently represents one of the most promising neuroprotective strategies for Parkinson's Disease (PD). However, the effect of this neurotrophic factor has never been tested in the newly ...

Encapsulated GDNF-producing C2C12 cells for Parkinson's disease: a pre-clinical study in chronic MPTP-treated baboons

Patrick Aebischer, Nicole Déglon

Glial cell line-derived neurotrophic factor (GDNF), a potent neurotrophic factor with restorative effects in a variety of rodent and primate models of Parkinson's disease (PD), could be of therapeutic value to PD. In this study, we show that intraventricul ...

Dose-dependent neuroprotective effect of ciliary neurotrophic factor delivered via tetracycline-regulated lentiviral vectors in the quinolinic acid rat model of Huntington's disease

Patrick Aebischer, Nicole Déglon

The ability to regulate gene expression constitutes a prerequisite for the development of gene therapy strategies aimed at the treatment of neurologic disorders. In the present work, we used tetracycline (Tet)-regulated lentiviral vectors to investigate th ...

GDNF and NGF released by synthetic guidance channels support sciatic nerve regeneration across a long gap

Patrick Aebischer, Eric Garrison Fine

The present work was performed to determine the ability of neurotrophic factors to allow axonal regeneration across a 15-mm-long gap in the rat sciatic nerve. Synthetic nerve guidance channels slowly releasing NGF and GDNF were fabricated and sutured to th ...

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 ...
