Det er økende interesse for DN T-celler, siden de blir innblandet i forskjellige patologiske tilstander slik som autoimmune sykdommer, kreft, transplantat-toleranse, og primær sykdommer i nyre inkludert akutt nyre-skade (AKI), glomerulonefritt 8, 13. Derfor er det behov for å bedre forstå og karakterisere pathophysiologic funksjonene til DN T-celler. Men for tiden er det en mangel på forståelse av disse cellenes funksjon i forhold til CD4 og CD8 T-celler. En viktig årsak er mangelen på DN T-celler i s...

Perifere αβTCR + CD3 + CD4 - CD8 - dobbel-negativ (DN) T-celler er delt inn i ulike undergrupper som besitter forskjellige fenotyper og funksjoner 1-4. DN T-celler er dårlig forstått, men i økende grad innblandet i patofysiologiske immunresponser i ulike sykdomsmodeller 4-6. DN T-celler er en unik immuncelletype som i økende grad implisert i regulering av en rekke immun-og autoimmunresponser, og modulering av allotransplant toleranse. 4-6, 9. De er sjeldne i perifert blod og sekundære lymfoide organer (milt og lymfeknuter ). Men de er store beboere i normal nyre og tarmepitel 10-12. Svært lite er kjent om deres funksjon 7 i nyrene i steady state og under patologiske tilstander som akutt nyreskade (AKI) forbundet med nyre transplmaur. På grunn av de intrikate roller i ulike immunceller i å regulere immunreaksjoner inkludert alloresponses, definere rollen for hver spiller er avgjørende for å forstå alloresponses og designe nye behandlingsformer. Gitt de betydelige antall DN T celler i nyrene etter fysiologiske og ulike sykdomstilstander, DN T-celler er sannsynlig å spille en avgjørende rolle i å regulere immunsystemet og autoimmune reaksjoner i mus og mennesker, og alloresponses i resipienter. Samlende men fortsatt spredte bevis impliserer DN T-celler i både patogene og immunsupprimerende funksjoner, men det er dårlig forstått hvorfor og hvordan de viser en spesifikk skadelig eller undertrykkende funksjon og hvordan miljøet påvirker dem. På grunn av deres lave overflod i nyrene, forbedrede fremgangsmåter for isolering er nødvendig. Det er for tiden ingen standard protokoll for isolering av DN T-celler fra than ikke lymfevev. Vår protokoll beskriver en ny fremgangsmåte for isolering av DN T-celler fra nyrene; Imidlertid kan fremgangsmåten også brukes for en rekke ikke-lymfoide vev.

isolation of double negative &#945;&#946; t cells from the kidney

Det er for tiden ingen standard protokoll for isolering av DN T-celler fra de ikke-lymfevev tross sin stadig rapportert engasjement i ulike immunresponser. DN T-celler er en unik immuncelletype som har vært implisert i regulering av immune og autoimmune responser og toleranse for allotransplants 1-6. DN T-celler er imidlertid sjelden i perifert blod og sekundære lymfoide organer (milt og lymfeknuter), men er store beboere i normal nyre. Svært lite er kjent om deres patofysiologiske funksjon 7 på grunn av sin sparsommelige i periferien. Vi har nylig beskrevet en omfattende fenotypiske og funksjonell analyse av denne befolkningen i nyrene 8 i steady state og under iskemi reperfusjonsskade. Analyse av DN T-celle funksjon vil bli sterkt forbedret ved å utvikle en protokoll for deres isolering fra nyrene. Her beskriver vi en ny protokoll som gjør det mulig isolasjon kon av svært rene ab CD4 + CD8 + T-celler og DN T-celler fra den murine nyre. Kort fortalt, vi fordøye nyrevevet ved hjelp av collagenase og isolere nyre mononukleære celler (KMNC) ved tettshetsgradient. Dette er etterfulgt av to trinn for å berike blodkreft T-celler fra 3% til 70% fra KMNC. Det første trinnet består av en positiv utvelgelse av hematopoetiske celler ved hjelp av et CD45 + isoleringssett. I det andre trinn blir DN T-celler isolert ved negativ fjerning av ikke-ønskede celler ved hjelp av CD4, CD8, og MHC klasse II monoklonale antistoffer og CD1d α-galcer tetramer. Denne strategien fører til en populasjon av mer enn 90% rene DN T-celler. Overflate farging med de ovenfor nevnte antistoffer etterfulgt av FACS-analyse er brukt for å bekrefte renheten.

Villtype C57BL / 6 (B6) nyre inneholder ca 1.5 til 2.1 x 10 6 mononukleære celler per nyre. Omtrent mindre enn 10% er blodkreft CD45 + celler. For fremstilling av nyre mononukleære celler (KMNC), blir nyrene kuttet i små biter, som vist i figur 1, etterfulgt av fordøyelse anvendelse av 5% kollagenase. Dette etterfølges av å utføre en tetthetsgradient-sentrifugering for å samle KMNC lag (fig. 2, venstre panel). KMNC ble deretter ...

Isolering av Double Negative αβ T celler fra nyre

DNabT celler er sjelden blant perifere T-celler; men de er rik på visse ikke-lymfoide vev. Vanskeligheter med å isolere DN T-celler fra ikke-lymfoid vev hindrer deres funksjonell analyse til tross for økende anerkjent patofysiologiske betydning. Vi beskriver en roman protokoll for isolering av høyrensede DN T-celler fra murin nyre.

There is currently no standard protocol for the isolation of DN T cells from the non-lymphoid tissues despite their increasingly reported involvement in ...
