有一个在DN T细胞增加的兴趣，因为他们被牵连在不同的病理情况，如自身免疫性疾病，癌症，移植耐受和肾脏，包括急性肾损伤（AKI）的原发疾病，肾小球肾炎8，13。因此，有必要更好地理解和描述的DN T细胞的病理生理功能。然而，目前仍缺乏这些细胞的功能相比，CD4和CD8 T细胞的了解。一个主要的原因是DN T细胞在次级淋巴器官的缺乏，因此难以取得足够的细胞在体外分析和过继...

周边αβTCR+ CD3 + CD4 - CD8 -双阴性（DN）T细胞被分成具有不同的表型和功能1-4各种子集。 DN T细胞知之甚少，但越来越多地被牵连在不同的疾病模型4-6病理免疫反应。 DN T细胞，是在各种免疫和自身免疫应答的调节和异体移植耐受的调制日益牵连了独特的免疫细胞类型。4-6，9它们是罕见的外周血和次级淋巴器官（脾和淋巴结）。然而，它们的正常肾和肠上皮10-12主要居民。很少有人知道他们在稳定状态功能7在肾和病理条件下，如肾transpl相关的急性肾损伤（AKI）下蚂蚁。 因为不同的免疫细胞在调节免疫反应，包括alloresponses，限定每个游戏者的角色的错综复杂的角色是在理解alloresponses和设计新疗法至关重要。给出的显著号码存在于生理和不同疾病状态下的肾DN T细胞，DN的T细胞很可能在移植受者起到在小鼠和人类调节免疫和自身免疫应答的关键作用，并且alloresponses。积累虽然仍散落证据牵连的DN T细胞在致病性和免疫功能，但它是知之甚少，为什么，以及他们如何表现出特定的有害或抑制功能和环境如何影响他们。 由于它们的低丰度在肾脏，分离的改进的方法是必要的。 目前还没有标准协议，用于从T DN T细胞的分离他非淋巴组织。我们的协议描述了一种新颖的方法，用于从肾脏DN T细胞的隔离;然而，也可用于各种非淋巴组织的方法。
