Teknikken beskrevet her benytter lignende reagenser kreves for å bygge ut bilayers i konvensjonelle flyt celle5 og kan bli brukt for å utføre avbilding av primære menneskelige T celle-bilayer grensesnitt3,4 ,15. Teknikken tilbyr en betydelig reduksjon i fluorescerende molekyler bruken og krever 10-20 x færre T celler i forhold til en flyt cellen systemet5, skape mulighet til ...

Vitenskapelig kunnskap om strukturfunksjonene T-celle immun synapser og deres link til den funksjonelle aktiviteten i T-celler er generert hovedsakelig fra studiet av linjer og kloner avledet fra PB. Til hvilken grad disse funnene knyttet til primær T-celler Hentet fra blod eller menneskelig lymfoid vev er fortsatt uklart, som synaptic grensesnittene av T-celler i lymfoide og andre vev ikke har analysert så langt. Viktigere, tyder nye data på at vev-resident og lymfoide organ-avledet T celler kan ha betydelige forskjeller i fenotypen og funksjonelle aktiviteten sammenlignet med de i PB6,7. Dette er ytterligere styrket behovet for å forstå funksjonene i T-celle synaptic grensesnittet i primær menneskelige T-celler.
Dette har vi utviklet en ny mini skala tilnærming utnytte lipid bilayers bygget i flerkanals flyt lysbilder slik at vi kan utføre avbilding av T-celle/bilayer grensesnitt med mindre enn 105 primære T celler isolert fra menneskelige PB og LN. Denne teknikken tillater studiet av Biofysiske egenskapene til primære menneskelige T-celle synaptic grensesnitt for å bedre modell og forstå i vivo celle-celle interaksjoner.

assessment of the synaptic interface of primary human t cells from peripheral blood and lymphoid tissue

Den nåværende forståelsen av dynamikken og strukturfunksjonene T-celle synaptic grensesnitt er i stor grad bestemt bruk av glass-støttet ut bilayers og i vitro-avledet T-celle kloner eller linjer1,2 ,3,4. Hvordan disse resultatene gjelder de primære menneskelige T cellene isolert fra blod eller lymfoid vev er ikke kjent, delvis på grunn av betydelige vanskeligheter å skaffe et tilstrekkelig antall celler for analyse5. Her ta vi dette gjennom utvikling av en teknikk utnytte flerkanals flyt lysbilder for å bygge ut lipid bilayers som inneholder aktivere og vedheft molekyler. Den lave høyden flyt lysbildene fremmer rask celle sedimentering synkronisere celle: bilayer vedlegg, og dermed slik at forskere til å studere dynamiske av synaptic grensesnitt dannelse og the kinetics av granulater utgivelsen. Vi bruker denne tilnærmingen å analysere synaptic grensesnittet for så lite som 104 til 105 primære cryopreserved T celler isolert fra lymfeknuter (LN) og perifert blod (PB). Resultatene viser at romanen planar lipid bilayer teknikken muliggjør studiet av Biofysiske egenskapene for primær menneskelige T-celler avledet fra blod og vev i forbindelse med helse og sykdom.
