MHC sınıf I tetramerleri farklı olarak, rutin uygulamalar için MHC sınıf II tetramerleri kullanımı özellikle aktivasyon bağımlılık 6,15-17 kısmen nedeniyle düşük-yakınlık oto-reaktif CD4 T hücrelerinin, bir ön-madde frekansları numaralandırmak için, zor olmaya devam etmektedir. Son zamanlarda, bu sorun, PLP&#39;ye 139-151, MOG 35-55 ve Myhc 334 gibi Otoantijenler, bir dizi için antijen-spesifik CD4 T hücreleri algılamak için bize izin &quot;, dextramers&quot; denilen tetramerler ne...

Majör histokompatibilite kompleksinin kullanımı antijene özgü CD4 T hücrelerinin saptanması için (MHC) sınıf II tetramerler bir sorun 1-7 olmuştur. MHC sınıf II tetramerler algılama hassasiyetini artırmak için, araştırma ekibi belirlenen nesil tetramers, &quot;dextramers&quot; 8 yarattı. Dextramers örneğin birkaç peptide gergin, biyotinile edilmiş monomerler, bir MHC molekülüne dekstran 9 bağlı olabilir birden fazla streptavidin-fluorofor kısımları konjüge edildiği dekstran omurgalar içerir. Böylece, birkaç MHC-peptid komplekslerini içeren MHC dextramers büyük agrega çok T hücre reseptörleri (TCRler) ile etkileşime girebilir. Bu grup, son zamanlarda çeşitli self-antijenlerine dextramers üretilir ve dextramers algılama hassasiyeti tetramerleri, yaklaşık 8 den fazla beş kat olduğu gösterilmiştir. Deney Sistemleri deneysel otoimmün ensefalomiyelit içerir (EAE) proteolipid protein (PLP) SJL farelerinde 139-151 ile indüklenen; EAE miyelin oligodendrosit glikoprotein (MOG) C57BL / 6 farelerinde 35-55 ile indüklenen; ve deneysel otoimmün miyokardit (EAM), kardiyak miyosin ağır zincir-α (Myhc) A / J farelerinde 334-352 ile neden oldu. Bu çalışma, PLP 139-151 kullanımını gösterir - ve Myhc 334-352 böylece florofor antikorlar kullanılarak gelen sinyalleri yükseltmek için ihtiyacı ortadan kaldırarak, direkt bir boyama protokolü geliştirerek özgüllük ile in situ olarak antijene spesifik CD4 T hücrelerini tespit etmek için bir dextramers Yaygın bir yaklaşım tetramerleri kullanımı ile kullanılabilir. Buna ek olarak, doku değerlendirilmesi kapsamlı bir yöntem de güvenilir bir şekilde yerinde 10 antijene spesifik CD4 T hücrelerinin frekansları numaralandırmak için tasarlanmış edilmiştir. In situ olarak antijen-spesifik T hücrelerinin aktivasyonunun tespiti seyirci neden olduğu belirli antijenik uyarıcılarla neden olduğu olaylar çizimi izin verir. Benzer şekilde, in situ tekniği de providhedef organ içinde antijen-spesifik T hücresi sızıntılar kinetiğini takip etmek için fırsatlar es.

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.
