細胞質カルシウムの動的変化は、生理学的および病理学的両方腺房細胞のイベントのために必要である。カルシウム、これらの発散効果はカルシウムシグナリング1の明確な空間的および時間的パターンに起因すると考えられている。例えば、腺房細胞から酵素液分泌は、分泌が行わ2を取るアピカルポールの限定された領域からのカルシウムスパイクにリンクされています。これとは対照的に、強烈な非振動カルシウムシグナルが続くグローバルカルシウム波が急性膵炎3,4につながる初期の病理学的イベントに関連付けられています。これらは内腺プロテアーゼ活性化、減少酵素の分泌、および腺房細胞傷害が含まれています。私たちの研究室では、in vivoおよびin vitroで 5-7両方病気につながるこれらの初期の病理学的事象を研究するために分離された膵臓の腺房を使用しています。ここで詳述方法は、CYを測定するために一次腺房細胞の単離を記載tosolicカルシウムレベルと細胞傷害。これらの細胞のアデノウイルス感染のための方法も提供される。

膵臓腺房細胞は、膵臓外分泌の主な実質細胞であると膵管に膵酵素の分泌の主な役割を果たしている。また、膵炎の開始のための部位である。ここでは、全体の膵臓組織から分離され、細胞内カルシウムシグナルの測定方法腺房細胞説明する。さらに、in vitroでの腺房細胞傷害を誘導する条件の中に、アデノウイルス構築物で、これらの細胞をトランスフェクトし、その後乳酸脱水素酵素、細胞損傷のマーカーの漏れを測定する技術が記載されている。これらの技術は、腺房細胞生理学と病理学を特徴づけるための強力なツールを提供します。

生理学的刺激に応答し腺房細胞のカルシウム測定の例を図3に設けられている。腺房細胞は、カルシウム染料のFluo-4にロードされ、アセチルコリンアナログカルバコール（のCCh; 1μM）を灌流した）8。細胞が頂端地域で開始し、基底地域3,9に伝播カルシウム波の形で答えた。 図3Bに示す代表的なトレーシングは、一般的に、1μMのカルバコールで観察さ?...
