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

세포 간 통신 세포막 유래 소체의 생물학적 역할에 대한 관심이 최근 증가하고있다. 미세 입자 (의원) 1 ㎛, 0.1 ㎛의 범위에서 직경이, 소체의 하나의 이러한 유형이며, 통상적으로 활성화 또는 사멸을 겪는 진핵 세포의 세포막에서 나타냈다. 여기에서 우리는 D. LMPs는 다단계 차동 원심 분리 과정을 통해 고립되고 유동 세포 계측법하여 특성화 티노 마이신 자극 세포 사멸 CEM T 세포에서 T 림프구에서 유래 미세 입자 (LMPs)의 생성을 설명합니다. 이 프로토콜은 또한 마우스 호흡기 차 기관지 조직 이식편 유래의 기관지 상피 세포에서의 아폽토시스 LMPs 효과를 입증하기위한 인 시츄 세포 사멸 검출 방법을 제안한다. 여기에 설명 된 방법은 체외에서 세포 사멸 림프구에서 LMPs의 풍부한 수량을 분리하기위한 재현 과정을 제공합니다. LMPs 유도이와 같이 각종 질병 모델의 특성을 평가하는 데 사용되며, 약리학 및 독성학 테스트 할 수있다. 기도 상피는 외부 환경과 하부 조직 사이의 보호 물리적 및 기능적 장벽을 제공 감안할 기관지 조직 이식편보다는 불멸화 상피 세포주를 사용기도 관 조직을 요구 수사 효과적인 모델을 제공한다.
