Hoewel de interface segment chambers vertonen meer robuuste synaptic reacties25,26,27,28, bieden onderdompeling kamers extra gemak voor patch-clamp opname en fluorescentie Imaging. Zo hebben we verschillende aspecten van veldopnames potentiële in acute hippocampal plakjes met behulp van een commerciële onderdompeling segment kamer die gemakkelijk kan worden uitgebreid tot de beeldvorming van ...

In 1951 waren de eerste gerapporteerde acute hersenen segment experimenten uitgevoerd1. In 1971, na succesvolle in vitro opnames uit de3 van piriform cortex2,en de ontdekking dat hippocampal neuronen onderling dwars langs de as van de septotemporal van de hippocampus4, één van verbonden de eerste in vitro opnames van hippocampal Neuronale activiteit werd bereikt5. De gelijkenis van de neurofysiologische of neurostructural parameters van neuronen in vivo en in vitro voorwaarden zijn nog steeds het onderwerp van een debat6, maar in 1975, Schwartzkroin7 aangegeven dat de basale eigenschappen van neuronen in vitro worden gehandhaafd en dat hoogfrequente stimulatie (dat wil zeggen, tetanization) van afferents in de hippocampal formatie induceert een langdurige versoepeling van synaptic potentieel8. Elektrofysiologische opname van neuronale activiteit in vitro breidde de studie van de cellulaire mechanismen van activiteit-afhankelijke synaptische plasticiteit9,10, die had ontdekt in 1973 door Bliss et al. 11 in vivo experimenten met konijnen.
De studie van neuronale activiteit of signalering trajecten in plakjes van de hersenen, met name in acute hippocampal segmenten, is nu een standaard tool. Verrassend, moeten in vitro experimenten echter nog worden herleid, zoals blijkt uit de verschillende benaderingen die nog steeds bestaan voor de opstelling en het onderhoud van acute hippocampal segmenten. Reid et al. (1988) 12 herzien de methodologische uitdagingen voor het onderhoud van acute hersenen segmenten in verschillende soorten segment kamers en de keuzes van het medium, pH, temperatuur en zuurstof niveau zwemmen. Deze parameters zijn nog steeds moeilijk te controleren in de zaal van de opname als gevolg van de op maat gemaakte elementen van in vitro segment-opname opstellingen. Publicaties kunnen worden gevonden dat misschien help te overwinnen enkele van de methodologische uitdagingen en die nieuwe soorten beschreven onderdompeling segment chambers, zoals een interstitiële 3D microperfusion systeem13, een kamer met verbeterde laminaire flow en zuurstof 14, een systeem met geautomatiseerde temperatuur controle15, en een multi-kamer opname systeem16opgeven. Aangezien deze kamers zijn niet gemakkelijk op te bouwen, rekenen de meeste wetenschappers op verkrijgbare segment kamers. Deze kamers kunnen worden gemonteerd op een Microscoop systeem, waardoor de combinatie van elektrofysiologie en fluorescentie imaging17,18,19. Aangezien deze kamers houden de segmenten van de hersenen ondergedompeld in kunstmatige cerebrospinale vloeistof (aCSF), moet een hoog stroomtarief bufferoplossing worden gehandhaafd, verhoging van de kosten van de toepassing van de drug. Daartoe hebben we een recyclingsysteem perfusie met uitstroom-carbogenation waarmee voldoende stabiliteit voor de lange termijn opname van veld potentieel in een onderdompeling segment kamer met behulp van een relatief kleine aCSF volume opgenomen. Bovendien, samengevat we hoe het gebruik van deze experimentele carbogenation/perfusie-systeem de uitkomst van de Synaptische plasticiteit activiteit-afhankelijke10 beïnvloedt en hoe remming van eukaryotische rek factor-2 kinase (eEF2K) moduleert synaptic transmissie20.

recording synaptic plasticity in acute hippocampal slices maintained in a small-volume recycling-, perfusion-, and submersion-type chamber system

Hoewel experimenten op segmenten van de hersenen zijn al in gebruik sinds 1951, problemen die de kans op het bereiken van een stabiele en succesvolle analyse van synaptische transmissie modulatie verminderen bij het uitvoeren van potentiële of intracellulaire veldopnames. Dit manuscript beschrijft de methodologische aspecten die nuttig wellicht bij het verbeteren van de experimentele omstandigheden voor het onderhoud van acute hersenen segmenten en voor het vastleggen van veld excitatory postsynaptisch potentieel in een kamer verkrijgbare onderdompeling met een uitstroom-carbogenation eenheid. De uitstroom-carbogenation helpt bij het stabiliseren van het zuurstofniveau in experimenten die afhankelijk zijn van de recycling van een kleine buffer reservoir ter verbetering van de kostenefficiëntie van de drug experimenten. Daarnaast presenteert het manuscript representatieve experimenten die onderzoeken van de effecten van verschillende carbogenation wijzen en stimulatie paradigma's op de activiteit-afhankelijke synaptische plasticiteit van synaptische transmissie.

In de sectie protocol beschreven we de voorbereiding van acute hippocampal segmenten uit het ventrale en tussenliggende deel van de hippocampal formatie (Figuur 1) van mannelijke C57BL/6 muizen en mannelijke Wistar ratten (5-8 weken). De positie van de hemisferen op de slicer platform helpt hen om stabiel te houden en elimineert de noodzaak van stabilisatie met agar of agarose. De perfusie-systeem zelf is gebaseerd op een peristaltische pomp geopereerd hoge r...
