De eerste vereiste voor succesvolle toepassing van deze werkwijze is het bereiken van voldoende transductie efficiëntie van de primaire T-cellen met de hemichain plaats. In onze ervaring, de combinatie van het gebruik van PG13 als verpakkingscellijn en retrovirale vector pmx als resultaten in een stabiele en efficiënte expressie van het geïntroduceerde gen in primaire T-cellen. PG13 packaging cellen kunnen eencellige gekloond om te selecteren op hoge titer inpakcellen transductie efficiëntie verbeteren. Bovendien is...

T-celreceptoren (TCR&#39;s) zijn heterodimere adaptieve immuun receptoren door T-lymfocyten tot expressie gebracht, bestaande uit een TCRα en TcR keten. Ze optreden via somatische herschikking van V (D) J-gensegmenten, die een zeer divers repertoire kan herkennen vrijwel onbegrensde configuratie van HLA / peptide-complexen produceert. Klinisch T cellen ontworpen om clonotypic TCRs die specifiek zijn voor met tumor geassocieerde antigenen tot expressie aangetoond werkzaamheid bij verschillende kankers 1. Veel TCRs gekloneerd hiertoe onvoldoende affiniteit voor het antigeen van belang, waardoor hun therapeutische toepassing te beperken. We beschrijven een werkwijze om deze beperking te overwinnen bestaande TCRs door gebruik keten centricity. Vermeld is dat een TCR hemichain een dominante rol in herkenning van het doelantigeen 2 kan spelen, hier genoemd centraal stellen. Crystal structurele analyses blijkt dat een centraalhemichain van een TCR kan verantwoordelijk voor het merendeel van de voetafdruk op het MHC / peptidecomplex 3,4. Dit begrip te gebruiken, hebben we eerder aangetoond dat het SIG35α TCRα kan koppelen met een divers repertoire van TcR ketens en onderhouden reactiviteit tegen MART1 27-35 peptide gepresenteerd door HLA-A2 5. Vergelijkbare resultaten werden verkregen met de TCR TAK1, waarbij de centrische TcR hemichain gekoppeld aan allerlei TCRα ketens en onderhouden reactiviteit voor WT1 235-243 peptide gepresenteerd door HLA-A24 6. Zowel MART1 en WT1 zijn tumor-geassocieerde antigenen. Chain-centricity werd ook toegepast op antigeen erkenning van CD1d-beperkte invariante natural killer (iNKT) TCR&#39;s te bestuderen, door het koppelen van de invariante Vα24-Jα18 (Vα24i) TCRα keten van humaan iNKT TCR&#39;s met verschillende Vβ11 TcR ketens 7. In alle gevallen konden we een de novo repertoire van TCRs genereren van transducing de centric TCR hemichain perifere bloed T-cellen, waarbij het ingebrachte hemichain gepaard met de endogene TCRα of TcR contra-ketens. In wezen centric hemichain dient als lokaas die kan worden gebruikt om de juiste contra-ketens, die bij elkaar gekoppelde vormen TCRs die de antigeenspecificiteit van belang, maar variërend in affiniteit te identificeren. Van deze nieuwe repertoires, waren we in staat om clonotypic TCR&#39;s te isoleren met een verbeterde interactie sterkte tegen het doelantigeen in vergelijking met reeds bestaande TCR&#39;s. Daarom geloven wij deze methode zal de pijpleiding identificeren optimale TCR&#39;s voor klinische toepassing te versnellen.

generating de novo antigen-specific human t cell receptors by retroviral transduction of centric hemichain

T-celreceptoren (TCR&#39;s) worden klinisch gebruikt om de specificiteit van T-cellen direct naar tumoren te richten als een veelbelovende modaliteit van immunotherapie. Daarom heeft TCRs klonen specifiek voor verschillende tumor-geassocieerde antigenen het doel van vele studies. Een effectieve T-cel op te wekken, moet de TCR het doelantigeen optimale affiniteit herkennen. Echter, klonen dergelijke TCRs uitdaging en vele beschikbare TCRs geweest bezitten suboptimaal affiniteit voor de verwante antigeen. In dit protocol beschrijven we een werkwijze voor het kloneren van de novo hoge affiniteit antigeenspecifieke TCRs Bestaande TCRs door gebruik hemichain centricity. Het is bekend dat sommige TCRs, elk TCRα of TcR hemichain niet gelijk bijdragen aan antigeen herkenning, en de dominante hemichain wordt aangeduid als centraal hemichain. We hebben aangetoond dat door het koppelen van de centrische hemichain met tegenstroom ketens verschillen van de oorspronkelijke contra-keten, kunnen wij het antigeen en handhavenpecificity, terwijl de interactie moduleren kracht voor de verwant antigeen. Aldus kan het therapeutisch potentieel van een bepaalde TCR worden verbeterd door het optimaliseren van de koppeling tussen de centrische en tegen hemichains.

Zonder voorkennis waarvan hemichain is keten-centric, de TCRα en TcR keten afzonderlijk worden gekloneerd en getransduceerd perifere bloed T-cellen, die werd uitgevoerd bij HLA-A24 / WT1 reactieve TAK1 TCR (figuur 1). Transductie van TAK1β leverde een aanzienlijk hogere frequentie van antigenspecifieke T-cellen. Omgekeerd transductie van een non-centric hemichain niet op de novo multimeer positieve T-cellen, zoals gezien met TAK1α keten (figuur 1).</s...

Generating De Novo Antigen-specific Human T Cell Receptors by Retroviral Transduction of Centric Hemichain

Hierin beschrijven we een nieuwe methode om antigeenspecifieke T-celreceptoren (TCR&#39;s) door het koppelen van de TCRα of TcR van een bestaande TCR, bezit de antigeen-specificiteit van interesse, met aanvullende hemichain van de perifere T-cel receptor repertoire genereren. De novo geproduceerde TCRs behouden antigeen-specificiteit met verschillende affiniteit.
