Focal expression of adeno-associated viral-mutant tau induces widespread impairment in an APP mouse model

Patrick Aebischer, Jean-Charles Bensadoun, Bernard Schneider

Adeno-associated virus serotype 6 (AAV6) viral vectors encoding mutant and normal tau were used to produce focal tau pathology. Two mutant forms of tau were used; the P301S tau mutation is associated with neurofibrillary tangle formation in humans, and the ...

Imaging brain amyloid deposition using grating-based differential phase contrast tomography

Patrick Aebischer, Jean-Charles Bensadoun, Peter Modregger, Marco Stampanoni

One of the core pathological features of Alzheimer's disease (AD) is the accumulation of amyloid plaques in the brain. Current efforts of medical imaging research aim at visualizing amyloid plaques in living patients in order to evaluate the progression of ...

Nigrostriatal overabundance of alpha-synuclein leads to decreased vesicle density and deficits in dopamine release that correlate with reduced motor activity

Patrick Aebischer, Graham Knott, Marco Cantoni, Ralf Schneggenburger, Özgür Genç, Jean-Charles Bensadoun, Wojciech Janusz Bobela, Safa Mohanna

alpha-Synuclein (alpha-syn) is a presynaptic protein present at most nerve terminals, but its function remains largely unknown. The familial forms of Parkinson's disease associated with multiplications of the alpha-syn gene locus indicate that overabundanc ...

Lentiviral vectors express chondroitinase ABC in cortical projections and promote sprouting of injured corticospinal axons

Jean-Charles Bensadoun, Bernard Schneider

Several diseases and injuries of the central nervous system could potentially be treated by delivery of an enzyme, which might most effectively be achieved by gene therapy. In particular, the bacterial enzyme chondroitinase ABC is beneficial in animal mode ...

Chronic delivery of antibody fragments using immunoisolated cell implants as a passive vaccination tool

Rolf Gruetter, Maria del Carmen Sandi Perez, Patrick Aebischer, Jean-Charles Bensadoun, Maurizio Molinari, Nicolas Bouche, Maria Isabel Cordero Campana, Veronica Setola, Osiris Marroquin Belaunzaran

BACKGROUND: Monoclonal antibodies and antibody fragments are powerful biotherapeutics for various debilitating diseases. However, high production costs, functional limitations such as inadequate pharmacokinetics and tissue accessibility are the current pri ...

Use of igf-1 and nt-3 in the treatment of x-linked adrenoleukodystrophy

Patrick Aebischer, Jean-Charles Bensadoun

The present invention is directed to new compositions uses thereof and related methods for the treatment of X- linked adrenoleukodystrophy. ...

Controlled release nanoparticle-embedded coatings reduce the tissue reaction to neuroprostheses

Philippe Renaud, André Mercanzini, Philippe Colin, Jeffrey Alan Hubbell, Jean-Charles Bensadoun, Sai Reddy

Controlled release coatings were developed for neuroprostheses with the aim of combating the tissue reaction following implantation in the brain. The coatings consist of poly(propylene sulfide) drug-eluting nanoparticles embedded in a poly(ethylene oxide) ...

Targeted overexpression of the parkin substrate Pael-R in the nigrostriatal system of adult rats to model Parkinson's disease

Patrick Aebischer, Jean-Charles Bensadoun, Bernard Schneider, Julien Dusonchet

Loss of function of parkin, an ubiquitin ligase, is responsible for autosomal recessive juvenile parkinsonism (AR-JP). Parkin-associated endothelin receptor-like receptor (Pael-R) was identified as an authentic substrate of parkin and is thought to accumul ...

in vivo Electrical Impedance Spectroscopy of Tissue Reaction to Microelectrode Arrays

Philippe Renaud, Arnaud Bertsch, André Mercanzini, Philippe Colin, Jean-Charles Bensadoun

The goal of this experiment was to determine the electrical properties of the tissue reaction to implanted microelectrode arrays. We describe a new method of analyzing electrical impedance spectroscopy data to determine the complex impedance of the tissue ...

Insulin-like growth factor-1 and neurotrophin-3 gene therapy prevents motor decline in an X-linked adrenoleukodystrophy mouse model

Patrick Aebischer, Jean-Charles Bensadoun

X-linked adrenoleukodystrophy (X-ALD) is the most common inherited peroxisomal disorder characterized by a progressive demyelination of the central nervous system. The marked loss of myelin and oligodendrocytes observed in the disease prompted us to evalua ...
