В отличие от I тетрамеров МНС класса, использование тетрамеров МНС класса II для обычных приложений продолжает оставаться сложной, особенно для перечисления частоты предшественники низкоаффинных аутореактивных лимфоцитов CD4, отчасти из-за их активации зависимости 6,15-17. В последн...

Использование главного комплекса гистосовместимости (МНС) класса II тетрамерами обнаружения антиген-специфических CD4 Т-клеток был вызов 1-7. Для повышения чувствительности обнаружения тетрамеров МНС класса II, исследовательская группа создала тетрамеров нового поколения, предназначенные &quot;dextramers&quot; 8. Dextramers содержать декстран магистралей, в которой множество стрептавидином флуорофор фрагменты конъюгируют таким образом, что несколько пептидов привязи, биотинилированные мономеры МНС могут быть присоединены к одной молекуле декстрана 9. Таким образом, крупные агрегаты МНС dextramers, которые содержат несколько комплексов МНС-пептид может взаимодействовать с несколькими рецепторами Т-клеток (TCR). Эта группа недавно генерируется dextramers для различных аутоантигены и показали, что чувствительность обнаружения dextramers был примерно в пять раз больше, чем тетрамеры 8. Экспериментальные системы включают экспериментальный аутоиммунный энцефаломиелит (EAЕ) индуцируют протеолипидного белка (PLP) 139-151 у мышей SJL; EAE индуцировали миелина олигодендроцитов (MOG гликопротеина) 35-55 в C57BL / 6 мышей; и экспериментальный аутоиммунный миокардит (EAM), индуцированный с сердечной миозина тяжелой цепи-α (MyHC) 334-352 в / J мышей. Это исследование демонстрирует использование PLP 139-151 - и MyHC 334-352 dextramers обнаружить антиген-специфических CD4 Т-клеток в месте со спецификой путем разработки прямое протокол окрашивания, тем самым устраняя необходимость усиливать сигналы от использования флуорофорные антитела, подход обычно используют с использованием тетрамеров. Кроме того, комплексный метод оценки тканей также был разработан, чтобы надежно перечислить частоты антиген-специфических Т-клеток CD4 на месте 10. Обнаружение антиген-специфических Т-клеток в месте допускает разграничение событий, вызванных конкретных антигенных стимулов от тех, которые вызваны активацией наблюдателем. Аналогичным образом, в технику Ситу также ProvidES возможности отслеживать кинетику антиген-специфических Т-клеток инфильтратов в целевых органах.

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.
