real-time imaging of heterotypic platelet-neutrophil interactions on the activated endothelium during vascular inflammation and thrombus formation in live mice

活性化された内皮細胞を媒介血栓症および血管炎症で活性化された血小板と白血球の相互作用（主に好中球）。1,2動脈損傷部位に血栓形成の間、活性化内皮に付着した血小板と内皮下マトリックスタンパク質は、好中球のローリングや接着をサポートしています3逆に、細静脈の炎症性条件の下で、活性化された内皮細胞に付着して好中球が循環する血小板の付着·蓄積をサポートすることができます。異血小板好中球凝集は細胞間の特異的受容体-カウンター受容体の相互作用によってシーケンシャルプロセスを必要とします。4それが活性化された内皮細胞は、それによって高剪断条件下で血小板の接着および蓄積を開始する、そのようなvon Willebrand因子として接着分子を放出することが知られている。5はまた、活性化された内皮細胞は、セレクチン発現させることにより、好中球のローリングとの接着性をサポートD細胞間接着分子-1（ICAM-1）は、それぞれ、低剪断条件下で4血小板P-セレクチンは通って好中球と相互作用するP-セレクチン糖タンパク質リガンド-1（PSGL-1）することにより、好中球β2インテグリンと企業の活性化を誘導する2種類の細胞間の接着。異型の血小板、好中球の相互作用は、全血または単離された細胞、6,7で決定されたin vitroの実験での進歩にもかかわらず、それらの研究では、血管疾患の間に酸化ストレス状態を操作することはできません。本報告では、蛍光標識を使用して、マウス血小板および好中球のマーカーに対する特異的抗体は、我々はTNF-α誘導炎症時に活性化された内皮細胞に血小板や好中球の異型相互作用をモニターするための詳細な生体顕微鏡プロトコルを記述したり、レーザー誘起に続く生きたマウスの精巣挙筋の微小血管の損傷。
