Wij danken Ekaterina Karelina voor hulp bij het opnemen van soundtrack voor de video, Ivan Molotkov voor 3D animatie en dr. Peter Blaesse voor CAG-EGFP-plasmide voorbereiding. Het werk werd ondersteund door subsidies van het Centrum voor Internationale Mobiliteit van Finland, de Finse Cultural Foundation en de Academie van Finland.

1. Introductie Creatie van transgene dieren is een krachtige methode van onderzoek van de genetische functies in levende dieren en een voor het ontrafelen van de ziekte-mechanisme 2,3 evenals voor het manipuleren van de eigenschappen van cellen 4. Echter, de procedure is nogal bewerkelijk, zeer tijdrovend en duur, zo rechtvaardigt het gebruik van alternatieve gen delivery methoden zoals virale injectie 5, neonatale ventriculaire injectie met elektrop...

Methoden van gen delivery in levende knaagdieren hersenen zijn goed ingeburgerd in utero elektroporatie 7,8,11,12 en, meer recentelijk, voor postnatale elektroporatie 6. Echter, deze methoden op basis van intraventriculaire injectie van het plasmide DNA, die kunnen worden beperkt voor verschillende toepassingen. Bijvoorbeeld, hebben deze methoden niet toe richten cellen in bepaalde hersengebieden, zoals de hippocampus, noch transfectie van dergelijke niet-trekkende soorten cellen zoals cor...

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

Creatie van transgene dieren is een standaard aanpak in het bestuderen van de functies van een gen van belang in vivo. Echter veel knock-out of transgene dieren zijn niet levensvatbaar zijn in die gevallen waarin het gemodificeerde gen wordt uitgedrukt of verwijderd in het hele organisme. Bovendien is een aantal compenserende mechanismen maken het vaak moeilijk om de resultaten te interpreteren. De compenserende effecten kunnen worden verlicht door ofwel de timing van de gen-expressie of het beperken van de hoeveelheid van de getransfecteerde cellen. De methode van postnatale non-ventriculaire microinjectie en in vivo elektroporatie maakt gerichte toediening van genen, siRNA of kleurstofmoleculen rechtstreeks naar een kleine regio van belang in de pasgeboren knaagdieren hersenen. In tegenstelling tot conventionele ventriculaire injectietechniek, deze methode maakt het mogelijk transfectie van niet-trekkende celtypen. Dieren getransfecteerd door middel van de hier beschreven methode kan worden gebruikt, bijvoorbeeld voor twee-foton in vivo imaging of in elektrofysiologische experimenten op acute hersenen plakjes.
