A differenza di tetrameri MHC di classe, l&#39;uso di MHC classe II tetrameri per applicazioni di routine continua ad essere impegnativo, soprattutto per enumerare le frequenze precursori di cellule T CD4 autoreattivi bassa affinità, dovute in parte alla loro dipendenza di attivazione 6,15-17. Recentemente, questo problema è stato aggirato con la creazione della prossima generazione di tetrameri, chiamati &quot;dextramers,&quot; ci permette di rilevare le cellule antigene-specifiche CD4 T per un certo numer...

L&#39;uso del complesso maggiore di istocompatibilità (MHC) di classe II tetrameri per la rilevazione di cellule antigene-specifiche CD4 T è stata una sfida 1-7. Per migliorare la sensibilità di rilevazione di MHC classe II tetrameri, il team di ricerca ha creato tetrameri di prossima generazione, denominati &quot;dextramers&quot; 8. Dextramers contengono dorsali destrano in cui più frazioni streptavidina-fluoroforo sono coniugate, in modo che diversi peptidi-tethered, biotinilati monomeri MHC possono essere collegati ad una molecola destrano 9. Così, grandi aggregati di dextramers MHC che contengono diversi complessi MHC-peptide possono interagire con molteplici recettori delle cellule T (TCR). Questo gruppo ha recentemente generato dextramers per varie auto-antigeni e ha dimostrato che la sensibilità di rilevazione di dextramers era di circa cinque volte più di tetrameri 8. I sistemi sperimentali includono encefalomielite autoimmune sperimentale (EAE) indotto con proteolipid proteina (PLP) 139-151 nei topi SJL; EAE indotta con mielina degli oligodendrociti glicoproteina (MOG) 35-55 in topi C57BL / 6; e miocardite autoimmune sperimentale (EAM) indotta con miosina cardiaca catena pesante-α (MyHC) 334-352 in A / J topi. Questo studio dimostra l&#39;uso di PLP 139-151 - e MyHC 334-352 dextramers per rilevare le cellule antigene-specifiche CD4 T in situ con specificità sviluppando un protocollo di colorazione diretta, eliminando così la necessità di amplificare i segnali utilizzando anticorpi fluoroforo, un approccio comunemente impiegato con l&#39;utilizzo di tetrameri. Inoltre, un metodo completo di valutare tessuti è anche stato studiato per enumerare affidabile le frequenze di cellule CD4 T antigene-specifiche in situ 10. Rilevamento di cellule T antigene-specifiche in situ permette delineazione di eventi provocati da stimoli antigenici specifici da quelle causate dall&#39;attivazione astanti. Allo stesso modo, la tecnica in situ anche provides opportunità per monitorare la cinetica di infiltrazioni di cellule T antigene-specifiche negli organi bersaglio.

in situ detection of autoreactive cd4 t cells in brain and heart using major histocompatibility complex class ii dextramers

This report demonstrates the use of major histocompatibility complex (MHC) class II dextramers for detection of autoreactive CD4 T cells in situ in myelin proteolipid protein (PLP) 139-151-induced experimental autoimmune encephalomyelitis (EAE) in SJL mice and cardiac myosin heavy chain-&#945; (Myhc) 334-352-induced experimental autoimmune myocarditis (EAM) in A/J mice. Two sets of cocktails of dextramer reagents were used, where dextramers+ cells were analyzed by laser scanning confocal microscope (LSCM): EAE, IAs/PLP 139-151 dextramers (specific)/anti-CD4 and IAs/Theiler&#8217;s murine encephalomyelitis virus (TMEV) 70-86 dextramers (control)/anti-CD4; and EAM, IAk/Myhc 334-352 dextramers/anti-CD4 and IAk/bovine ribonuclease (RNase) 43-56 dextramers (control)/anti-CD4. LSCM analysis of brain sections obtained from EAE mice showed the presence of cells positive for CD4 and PLP 139-151 dextramers, but not TMEV 70-86 dextramers suggesting that the staining obtained with PLP 139-151 dextramers was specific. Likewise, heart sections prepared from EAM mice also revealed the presence of Myhc 334-352, but not RNase 43-56-dextramer+ cells as expected. Further, a comprehensive method has also been devised to quantitatively analyze the frequencies of antigen-specific CD4 T cells in the &#8216;Z&#8217; serial images.

In questo rapporto, nella rilevazione in situ di antigene-specifiche, autoreattivi cellule T CD4 di colorazione diretto con MHC di classe II dextramers è descritto. Sezioni cerebrali appena tagliato sono state derivate da topi EAE e colorate con cocktail contenenti PLP 139-151 (controllo) dextramers e anti-CD4 (specifico) o TMEV 70-86. I primi pannelli in figura 1 mostra l&#39;analisi LSCM di sezioni cerebrali costained con PLP 139-151 dextramers (rosso) e di anticorpi CD4 (verde), in...
