In questo video, abbiamo dimostrato come preparare e mantenere camere compartimenti per l&#39;uso nei neuroni DRG coltura. Fatto correttamente, questo sistema consente la separazione del corpo cellulare dal assone al fine di studiare meccanismi attraverso i quali neurotrofine segnale attraverso lunghi assoni. Poiché non vi è l&#39;isolamento fluidico tra i compartimenti, permette per la stimolazione selettiva o il trattamento di un compartimento senza altri compartimenti essere colpiti. Culture camera compartimentate in grado di supportar...

preparation and maintenance of dorsal root ganglia neurons in compartmented cultures

I neuroni estendere i processi assoni che sono molto lontane dal corpo cellulare a innervare tessuti bersaglio, dove sono richiesti obiettivi derivati ​​fattori di crescita per la sopravvivenza neuronale e la funzione. Neurotrofine sono specificamente tenuti a mantenere la sopravvivenza e la differenziazione dei neuroni sensoriali che innervano ma il problema di come questi target-derivati ​​neurotrofine comunicare al corpo cellulare dei neuroni che innervano è stata un&#39;area di ricerca attiva da oltre 30 anni. Il modello più comunemente accettata di come i segnali neurotrofina raggiungere il corpo cellulare propone di segnalazione endosomi portare questo segnale retrogrado lungo l&#39;assone. Al fine di studiare il trasporto retrogrado, un sistema di coltura è stato originariamente ideato da Robert Campenot, in cui corpi cellulari sono isolati dal loro assoni. La tecnica di preparazione di queste camere compartimenti per la coltura dei neuroni sensoriali ricapitola la stimolazione selettiva di terminazioni neuronali che si verifica in vivo seguente comunicato del target di derivazione neurotrofine. Retrograda di segnalazione eventi che richiedono lunga distanza retrograda dipendente microtubuli hanno importanti implicazioni per il trattamento di patologie neurodegenerative.
