Il pMHC tetramero metodo basato arricchimento delle cellule presentata da questo protocollo è un potente strumento per lo studio delle cellule T epitopo-specifici di cellule T endogene repertori. L&#39;utilizzo di tetrameri pMHC consente il rilevamento di epitopo-specifiche cellule T basati direttamente sulla capacità dei loro TCR per legare ligandi affini pMHC. L&#39;arricchimento fornisce un livello di sensibilità in modo tale che le popolazioni estremamente rari di antigene-specifiche cellule T può essere rilevat...

peptide:mhc tetramer-based enrichment of epitope-specific t cells

Una necessità di base per i ricercatori che studiano immunità adattativa con modelli sperimentali in vivo è la capacità di identificare cellule T in base al loro recettore antigene sulla cellula T (TCR) specificità. Molti metodi indiretti sono disponibili in cui una popolazione di cellule T bulk è stimolata in vitro con un antigene specifico epitopo-specifici e le cellule T sono identificati mediante la misurazione di una risposta funzionale come proliferazione, produzione di citochine, o l&#39;espressione di marcatori di attivazione 1. Tuttavia, questi metodi solo identificare epitopi specifici per cellule T presentano una delle tante possibili funzioni, e non sono sufficientemente sensibili per rilevare le cellule T epitopo-specifici a frequenze precursori naive. Un&#39;alternativa popolare è il modello transgenico trasferimento TCR adottiva, in cui le cellule T monoclonali da un topo transgenico TCR sono seminati in istocompatibili host per creare una vasta popolazione precursore di epitopo-specifiche cellule T che possono essere facilly cingolato con l&#39;uso di un anticorpo marcatore congenic 2,3. Mentre potente, questo metodo soffre di artefatti sperimentali associate alla frequenza fisiologica di cellule T con specificità per un singolo epitopo 4,5. Inoltre, questo sistema non può essere usato per studiare l&#39;eterogeneità funzionale di epitopo-specifici cloni di cellule T all&#39;interno di una popolazione policlonale. Il modo ideale per studiare l&#39;immunità adattativa dovrebbe coinvolgere il rilevamento diretto di cellule T epitopo-specifici del repertorio endogeno delle cellule T utilizzando un metodo che distingue la specificità TCR esclusivamente dal suo legame con l&#39;affine peptide: MHC (pMHC) complessi. L&#39;utilizzo di tetrameri pMHC e citometria di flusso realizza questo 6, ma è limitata alla rilevazione di popolazioni ad alta frequenza di epitopo-specifiche cellule T solo trovati seguente indotta da antigene espansione clonale. In questo protocollo, si descrive un metodo che coordina l&#39;uso di tetrameri pMHC e magnetecnologia delle celle tic arricchimento abilitare il rilevamento di frequenza estremamente bassa epitopo-specifiche cellule T di topo tessuti linfoidi 3,7. Con questa tecnica, si può globalmente intera traccia epitopo-specifiche popolazioni di cellule T endogene in topi in tutte le fasi della risposta immunitaria.
