Microparticles (MPs) are biologically active submicron membrane vesicles released following cell activation or apoptosis. MPs are derived from both healthy and damaged cells and are implicated in many physiological and pathological processes.1 MPs have been detected not only in human plasma, but also in inflammatory and apoptotic tissue. The biological utility of cell membrane&#8211;derived MPs has been demonstrated in various settings, including cell signalling models and as pharmacological tools.2,3 We previously demonstrated that LMPs derived from T lymphocytes following actinomycin D stimulation (to induce apoptosis) suppress angiogenesis and inhibit endothelial cell survival and proliferation.4,5 The antiangiogenic effects of LMPs may vary significantly depending on the stimuli used to activate T lymphocytes in vitro.6
The airway epithelium functions as a protective physical and functional barrier. Increased numbers of T lymphocytes in the airway can contribute to cell damage and airway inflammation.7 We have shown that LMPs induce apoptosis of human bronchial epithelial cells,8 which indicated LMPs may change barrier function of bronchial epithelium in vivo. Apoptotic cells can be identified using the TUNEL method, which detects in situ DNA fragmentation. 
The overall goal of this protocol is to illustrate the in vitro production of LMPs from a T lymphocyte cell line, and to demonstrate their proapoptotic effect on airway epithelial cells. In situ cell death detection demonstrated that LMPs strongly induce airway bronchial epithelial cell death, suggesting that LMPs-mediated injury to the airway epithelium may impact barrier function of the damaged epithelium.

generation of lymphocytic microparticles and detection of their proapoptotic effect on airway epithelial cells

تزايد الاهتمام في الأدوار البيولوجية للخلية الحويصلات المشتقة من الغشاء في التواصل خلية خلية في السنوات الأخيرة. المجهرية الدقيقة (النواب) هي واحدة مثل هذا النوع من الحويصلات، والتي تتراوح قطرها من 0.1 ميكرومتر إلى 1 ميكرومتر، وتسلط عادة من غشاء البلازما من خلايا حقيقية النواة تمر تفعيل أو موت الخلايا المبرمج. نحن هنا وصف جيل من T-المستمدة اللمفاويات المجهرية الدقيقة (LMPS) من خلايا CEM T أفكارك حفز مع أكتينوميسين يتم عزل D. LMPS من خلال عملية الطرد المركزي التفاضلي متعددة الخطوات، وتميزت باستخدام التدفق الخلوي. ويعرض هذا البروتوكول أيضا في الموقع موت الخلايا طريقة الكشف لإثبات تأثير proapoptotic من LMPS على الخلايا الظهارية الشعب الهوائية المستمدة من الماوس الابتدائية الجهاز التنفسي إإكسبلنتس الأنسجة الشعب الهوائية. الطرق الموضحة في هذه الوثيقة توفر الإجراء استنساخه لعزل كميات وفيرة من LMPS من الخلايا الليمفاوية أفكارك في المختبر. المستمدة LMPSفي هذه الطريقة يمكن استخدامها لتقييم خصائص النماذج المرض المختلفة، والصيدلة وعلم السموم الاختبار. وبالنظر إلى أن ظهارة الهوائية تقدم حاجز مادي وعملي وقائي بين البيئة الخارجية والأنسجة الكامنة، واستخدام إإكسبلنتس الأنسجة الشعب الهوائية بدلا من خطوط الخلايا الظهارية خلد يوفر نموذج فعال للتحقيقات التي تتطلب الأنسجة المسالك الهوائية.

واتسمت LMPS مع annexin V تلطيخ 10 بواسطة خلية مضان تنشيط الفرز (FACS) تحليل وبوابات باستخدام 1 ميكرومتر الخرز التي كانت 97٪ من النواب (≤1 ميكرون) annexin-V-Cy5 الإيجابي (الشكل 1A و 1B). عادة، تم الحصول على حوالي 2.5 ملغ من LMPS بعد هذا البروتوكول. إإكسبلنتس الأنسجة الشعب الهوائ?...
