Dynamische Veränderungen in zytosolischen Kalzium sind notwendig sowohl für physiologische und pathologische Azinuszelltumoren Veranstaltungen. Diese unterschiedlichen Effekte von Calcium werden gedacht, um aus unterschiedlichen räumlichen und zeitlichen Muster der Calcium-Signalgebung 1 führen. Zum Beispiel werden Enzym und Sekretion aus der Azinuszelltumoren Calcium Spikes aus einem begrenzten Bereich des apikalen Pol, wo Sekretion erfolgt 2 verbunden. Im Gegensatz dazu ist ein globales Calcium Welle durch intensive nicht-oszillierende Kalzium-Signale verfolgt mit frühen pathologischen Ereignissen, die zu einer akuten Pankreatitis führen 3,4 zugeordnet. Dazu gehören intra-acinar Proteaseaktivierung, reduzierte Enzym-Sekretion und Azinuszelltumoren Verletzungen. Unser Labor verwendet isoliert Pankreasazini diese frühen pathologischen Ereignissen, die Krankheit sowohl in vivo und in vitro 5-7 führen zu studieren. Die Methoden detailliert beschreiben Isolierung von primären Azinuszellen zum Zweck der Messung cytosolic Kalziumspiegel und Zellschäden. Verfahren für die adenovirale Infektion dieser Zellen wird ebenfalls bereitgestellt.

preparation of pancreatic acinar cells for the purpose of calcium imaging, cell injury measurements, and adenoviral infection

Das Pankreas Azinuszelltumoren ist die wichtigste Parenchymzelle des exokrinen Pankreas und spielt eine führende Rolle bei der Sekretion von Pankreas-Enzyme in den Pankreasgang. Es ist auch der Ort für die Einleitung der Pankreatitis. Hier beschreiben wir, wie Azinuszellen isoliert werden aus ganzen Pankreasgewebe und intrazellulären Calcium-Signale werden gemessen. Darüber hinaus beschreiben wir die Techniken der Transfektion dieser Zellen mit adenoviralen Konstrukte und anschließend Messung der Leckage von Laktat-Dehydrogenase, ein Marker der Zellschädigung, während die Bedingungen Azinuszelltumoren Verletzungen in vitro zu induzieren. Diese Techniken bieten ein leistungsfähiges Werkzeug, um Azinuszelltumoren Physiologie und Pathologie zu charakterisieren.

Ein Beispiel Azinuszelltumoren Calcium, welche in Reaktion auf physiologische Stimuli ist in 3 bereitgestellt. Acinar Zellen wurden mit dem Calcium geladen Farbstoff Fluo-4 und durchströmt mit dem Acetylcholin analogen Carbachol (CCH, 1 uM)) 8. Zellen reagierten in Form eines Calcium-Welle, die in dem apikalen Bereich initiiert und breitet sich zur basolateralen Bereich 3,9. Repräsentative Kurven in 3B gezeigt zeigen die typische Peak-Plateau-Muster häufig mit 1...
