Met virussen neurale circuits studie een relatief high throughput werkwijze voor het analyseren verbonden neuronen. Echter, het genereren van zowel VSV en RABV virionen is niet triviaal. Hoewel het bovenstaande protocol voor reddings virus van cDNA wordt, is het nog steeds een lage waarschijnlijkheid event. De niveaus van elk van de N, P en L plasmiden moeten fijn worden aangepast en vele proeven en gerepliceerd moet worden gedaan om virale rescue waarborgen.

viral tracing of genetically defined neural circuitry

Klassieke methodes voor het bestuderen van neuronale circuits zijn vrij geringe capaciteit. Transsynaptic virussen, met name de pseudorabies (PRV) en rabiësvirus (RABV), en meer recent vesiculair stomatitis virus (VSV), voor het bestuderen schakelingen, wordt steeds populairder. Deze hogere doorvoersnelheid methoden gebruiken virussen die overbrengen tussen neuronen in zowel de anterograde of retrograde richting. Onlangs werd een aangepaste RABV voor monosynaptic retrograde tracing ontwikkeld. (Figuur 1A). In deze methode wordt het glycoproteïne (G) gen verwijderd uit het virale genoom en alleen in bevoorraad gerichte neuronen. Infectie specificiteit wordt bereikt door het substitueren van een chimeer G, bestaande uit het extracellulaire domein van de ASLV-A glycoproteïne en het cytoplasmatische domein van de G-RABV (A / RG) voor de normale RABV-G 1. Deze chimere G infecteert specifiek cellen die de TVA-receptor 1. Het gen dat codeert TVA kan zijn delivered op verschillende manieren 2-8. Na RABV-G infectie van een TVA-expressie neuron kan de RABV verzenden naar andere, synaptisch verbonden neuronen in een achteruitgaande richting van nature eigen G was geleverd samen met TVA receptor. Deze techniek labels een relatief groot aantal ingangen (5-10%) 2 op een bepaald celtype, die een bemonstering van alle ingangen op een bepaald celtype starter. We hebben onlangs gemodificeerd deze techniek VSV als een tracer transsynaptic 9. VSV heeft een aantal voordelen, waaronder de snelheid van genexpressie. Hier hebben we detail een nieuwe virale tracing systeem met behulp van VSV nuttig voor het sonderen van microcircuits met verhoogde resolutie. Terwijl de oorspronkelijke gepubliceerde strategieën Wickersham et al.. 4 en Beier et al.. 9 vergunning etiket van neuronen die aanvankelijk op geïnfecteerd TVA-expressie-cellen hier VSV werd ontworpen om slechts aan TVA-expressie brengende cellen (Figuur 1B). Het virus wordt eerst met pseudogetypeerd RABV-G infectie van neuronen stroomafwaarts van TVA-expressie neuronen mogelijk. Na het infecteren deze eerste populatie van cellen, het virus infecteren model alleen TVA tot expressie brengende cellen. Omdat de transsynaptic virale verspreiding beperkt tot TVA tot expressie brengende cellen, of afwezigheid van connectiviteit van gedefinieerde celtypes kunnen worden onderzocht met hoge resolutie. Een experimentele stroomschema van deze experimenten wordt getoond in Figuur 2. Hier laten we een model circuit, dat van richting-selectiviteit in de muis retina. We onderzoeken de connectiviteit van starburst amacrine cellen (SBZ) aan retinale ganglioncellen (RGC).
