1. Présentation Création d&#39;animaux transgéniques est une méthode puissante d&#39;investigation des fonctions des gènes chez les animaux vivants et pour une maladie de mécanisme de démêler 2,3 ainsi que pour la manipulation des propriétés des cellules 4. Toutefois, la procédure est assez laborieuse, extrêmement longue et coûteuse, ce qui justifie l&#39;utilisation de méthodes alternatives de livraison de gènes viraux tels que l&#39;injection <...

Les méthodes de livraison de gènes dans le cerveau de rongeurs vivants sont bien établies pour l&#39;électroporation in utero 7,8,11,12 et, plus récemment, par électroporation postnatale 6. Cependant, ces méthodes sont basées sur l&#39;injection intraventriculaire de l&#39;ADN plasmidique, qui peut être limitant pour plusieurs applications. Par exemple, ces méthodes ne permettent pas de cibler des cellules dans certaines régions du cerveau telles que l&#39;hippocampe, ni la tran...

gene delivery to postnatal rat brain by non-ventricular plasmid injection and electroporation

Création d&#39;animaux transgéniques est une approche standard dans l&#39;étude de fonctions d&#39;un gène d&#39;intérêt in vivo. Toutefois, de nombreux KO ou des animaux transgéniques ne sont pas viables dans les cas où le gène modifié qui est exprimé ou supprimés dans l&#39;organisme entier. Par ailleurs, une variété de mécanismes compensatoires font qu&#39;il est souvent difficile d&#39;interpréter les résultats. Les effets compensatoires peuvent être atténuées par le calendrier soit l&#39;expression du gène ou de limiter la quantité de cellules transfectées. La méthode de non-ventriculaire postnatale microinjection et électroporation in vivo permet l&#39;administration ciblée de gènes, siRNA ou des molécules de colorant directement à une petite région d&#39;intérêt dans le cerveau de rongeurs nouveau-né. Contrairement à la technique du ventricule injection classique, cette méthode permet la transfection de types de cellules non-migrateurs. Animaux transfectées au moyen de la méthode décrite ici peut être utilisé, par exemple, pour deux photons en imagerie in vivo ou dans des expériences électrophysiologiques sur tranches de cerveau aigu.
