Bu tür otoimmün hastalıklar, kanser, graft tolerans ve akut böbrek hasarı (AKI) da dahil olmak üzere böbrek hastalıkları, birincil olarak farklı patolojik koşullarda karıştıktan çünkü DN T hücrelerinde artan bir ilgi vardır, 8, 13, glomerülonefrit. Bu nedenle, daha iyi bir DN T hücrelerinin patofizyolojik fonksiyonları ve karakterize etmek için bir ihtiyaç vardır. Ancak, şu anda CD4 ve CD8 T hücreleri ile karşılaştırıldığında, bu hücrelerin fonksiyonu içinde anlayışında...

Periferik αβTCR + CD3 + CD4 - CD8 - double-negatif (DN) T hücreleri fenotip ve işlevlerini 1-4 sahip çeşitli tiplerin ayrılır. DN T hücreleri, tam olarak anlaşılamamıştır, fakat çok daha farklı hastalık modellerinde 4-6 patofizyolojik bağışıklık tepkilerine dahil edilmektedir. DN T hücrelerinin artan çeşitli bağışıklık ve oto-bağışıklık tepkilerinin düzenlenmesi ve allotransplant tolerans modülasyonunda rol benzersiz bir bağışıklık hücresi bir türüdür. 4-6, 9 Bunlar dalak ve lenf düğümleri (periferal kan ve sekonder lemfoid organlarda nadirdir .) Ancak, normal böbrek ve bağırsak epitel 10-12 önemli sakinleri vardır. Çok az kararlı halde böbrekte işlevlerine yaklaşık 7 ve böbrek transpl ile bağlantılı akut böbrek hasarı (AKI) gibi patolojik koşullar altında bilinirkarınca. Çünkü her oyuncunun rolünü tanımlayan, alloresponses de dahil olmak üzere bağışıklık tepkilerini düzenleyen farklı bağışıklık hücrelerinin karmaşık rolleri alloresponses anlamak ve yeni terapötik tasarımı önemlidir. Ve fizyolojik koşullar altında, farklı hastalık, böbrekte bulunan DN T hücrelerinin önemli sayıda göz önüne alındığında, DN T hücreleri transplant alıcılarında kritik farelerde ve insanlarda bağışıklık ve oto-bağışıklık tepkileri düzenlenmesinde bir rol oynayabilir ve alloresponses muhtemeldir. Hala dağınık delil olsa Biriken hem patojenik ve bağışıklık fonksiyonları DN T hücrelerini implicates ama neden ve nasıl belli bir zararlı ya da baskılayıcı fonksiyonunu sergilemek ve çevre onları nasıl etkilediğini de anlaşılamamıştır. Nedeniyle böbrekte düşük bolluğu nedeniyle, izolasyon geliştirilmiş yöntemler gerekmektedir. T DN T hücrelerinin izole edilmesi için standart bir protokol bulunmamaktadıro non-lenfoid dokular. Bizim protokol böbrekten DN T hücrelerinin izole edilmesi için yeni bir yöntem tarif eder; Bununla birlikte, yöntem, aynı zamanda, çeşitli lenfoid olmayan dokular için kullanılabilir.

isolation of double negative &#945;&#946; t cells from the kidney

Lenfoid olmayan dokulardan DN T hücrelerinin izole edilmesi için standart bir protokol, çeşitli immün yanıtların onların daha çok rapor katılımı rağmen bulunmamaktadır. DN T hücreleri Allotransplantlar 1-6 bağışıklık ve oto-bağışıklık yanıtlarını ve tolerans düzenlenmesinde implike edilmiştir özel bir immün hücre türüdür. DN T-hücreleri, periferik kan ve sekonder lemfoid organlarda (dalak ve lenf düğümleri) nadir, ancak, fakat normal böbrekte önemli sakinleri vardır. Çok az nedeniyle çevrede kendi azlığı onların patofizyolojik işlevi 7 hakkında bilinmektedir. Biz son zamanlarda sürekli halde ve iskemi reperfüzyon yaralanması esnasında böbrek 8&#39;de bu nüfusun kapsamlı bir fenotipik ve fonksiyonel analiz nitelendirdi. DN T hücresi işlevinin analizi büyük ölçüde böbrek kendi izolasyon için bir protokol geliştirilerek artırılacaktır. Burada, biz isolatio sağlayan bir roman protokol açıklarMurin böbrekten oldukça saf ab CD4 + CD8 + T hücreleri ve T hücre DN n. Kısaca, biz kollajenaz kullanılarak böbrek doku sindirmek ve yoğunluk gradyanı ile böbrek mononükleer hücreleri (KMNC) izole. Bu KMNC den% 70 &#39;den% 3 hematopoietik T hücreleri zenginleştirmek için iki aşama takip eder. İlk adım, CD45 + izolasyon kiti kullanılarak hematopoietik hücrelerin pozitif seçim oluşur. İkinci aşamada, DN T hücreleri negatif CD4, CD8 ve MHC sınıf II monoklonal antikorlar ve CD1d α-GalCer tetramer kullanılarak olmayan arzu edilen hücreler ayrılmasıyla izole edilmektedir. Bu strateji,% 90&#39;dan fazla saf DN T hücre popülasyonu yol açar. , FACS analizi ile, ardından yukarıda belirtilen antikorlar ile lekeleme yüzey saflığını teyit etmek için kullanılır.

Yabani tip C57BL / 6 (B6), böbrek böbrek başına yaklaşık 1.5-2.1 x 10 6 mononükleer hücreleri içerir. Yaklaşık olarak en fazla% 10 CD45 + hematopoietik hücrelerdir. % 5 kolajenaz ile sindirme ile ve ardından, Şekil 1&#39;de gösterildiği gibi böbrek tek çekirdekli hücreleri (KMNC) hazırlanması için, böbrekler küçük parçalar halinde kesilir. Bu KMNC tabakası (Şekil 2, sol panel) toplamak için, bir yoğunluk g...

Isolation of Double Negative ÃƒÅ½Ã‚Â±ÃƒÅ½Ã‚Â² T Cells from the Kidney

Böbrek gelen Çift Negatif αβ T Hücreleri İzolasyon

DNabT hücreleri periferal T-hücreleri arasında nadirdir; Bununla birlikte, belli olmayan lenfoid dokuda bol miktarda bulunmaktadır. Non-lenfoid doku DN T hücrelerini izole Zorluk patofizyolojik önemini kabul kapasitelerine rağmen fonksiyonel analizini engellemektedir. Bu murin böbreğinden yüksek derecede arıtılmış DN T hücrelerinin izole edilmesi için yeni bir protokol açıklar.
