MERK: Mann C57BL / 6 mus (5-7 uker gammel) er fra Charles River Laboratories International, Inc. (St-Constant, Quebec, Canada.) Og manipulert i henhold til protokoller godkjent av CHU Sainte-Justine Animal Care komiteen. Mus bronkial vev explants gi en god kilde til primær bronkial epitelceller for å undersøke apoptosiske effekter LMPs på epitelceller. Denne protokollen beskriver in vitro-dannelse av LMPs, så vel som en fremgangsmåte for påvisning av apoptotiske epitelceller på LMPs-behandlede bronkiale...

Parlamentsmedlemmer er aktive formidlere av interkrysstale og deres studie er lovende i mange områder av vitenskap. 11 Denne studien presentert en detaljert protokoll for in vitro storskala generasjon LMPs avledet fra en apoptotisk T cellelinje. Disse parlamentsmedlemmer uttrykker et stort repertoar av lymfocytt molekyler og er biologisk innblandet i reguleringen av mobilnettet og vev homeostase. Imidlertid kan LMPs avledet fra forskjellige kilder være biologisk forskjellig. 4,9,12,13 </...

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

Interessen for de biologiske roller cellemembranen-avledet vesikler i celle-celle kommunikasjon har økt de siste årene. Mikropartikler (MPS) er en slik type vesikler, som varierer i diameter fra 0,1 pm til 1 pm, og vanligvis skur fra plasmamembranen av eukaryote celler som gjennomgår apoptose eller aktivering. Her beskriver vi generering av T-lymfocytt-avledede mikropartikler (LMPs) fra apoptotiske CEM T-celler stimulert med actinomycin D. LMPs isoleres gjennom en flertrinnsprosess differensialsentrifugering og karakterisert ved hjelp av flow cytometri. Denne protokollen presenterer også en in situ celledød deteksjonsmetode for å demonstrere apoptosiske effekten av LMPs på bronkial epitelceller som stammer fra mus primære luftveis bronkial vev explants. Fremgangsmåtene beskrevet heri tilveiebringe en reproduserbar fremgangsmåte for isolering av rikelig mengder LMPs fra apoptotiske lymfocytter in vitro. LMPs avledetpå denne måte kan brukes til å evaluere egenskapene til forskjellige sykdomsmodeller, og for farmakologi og toksikologi testing. Bruken av bronkial vev eksplantater fremfor immortaliserte epiteliale cellelinjer gitt at luftveisepitel har en beskyttende fysiske og funksjonelle barriere mellom det ytre miljø og det underliggende vev, gir en effektiv modell for undersøkelser som krever luftveiskanalen vev.

LMPs var preget med annexin V farging 10 av fluorescens-aktivert celle sortering (FACS) analyse og gated bruker en mikrometer perler der 97% av parlamentsmedlemmer (≤1 mikrometer) ble annexin-V-Cy5 positive (figur 1A og 1B). Vanligvis ble omtrent 2,5 mg LMPs oppnådd etter denne protokollen. Bronkial vev explants fra C57BL / 6 mus ble utsatt for kjøretøy og LMPs behandling. Histopatologisk analyse av bronkial seksjoner viste effekten av LMPs på den strukturelle integritet av det bronkial...
