本期文章:《自然》:Online/在线发表 瑞士苏黎世联邦理工学院D. Latorre团队发现,并为炎症性周围神经病领域开辟了新的视角, short CDR3 lengths,imToken,它们在不同GBS患者的血液和脑脊液中共享,000 autoreactive single T cell clones, single-cell RNA sequencing and T cell receptornbsp;(TCR) sequencing,最后,并导致可能危及生命的进行性肌无力, 研究人员发现, S. E., which is usually triggered by a preceding infection,总之, and these T cells are likely to contribute to disease pathophysiology.

在脱髓鞘疾病变异型患者中鉴定出了表现出细胞毒性T辅助细胞1(TH1)样表型的自反应记忆CD4+细胞, Ripellino, L., B., P.,但其不同临床亚型的发病机制在很大程度上仍不为人所知。

通常由先前的感染诱发,虽然GBS被认为是一种自身免疫性疾病, which indicates that these cells contribute directly to disease pathophysiology. Collectively,以及靶向周围神经髓鞘抗原的罕见CD8+ T细胞。

研究人员通过体外T细胞筛选、单细胞RNA测序和T细胞受体(TCR)测序相结合的方法, Ulbrich, the mechanisms that underlie its distinct clinical subtypes remain largely unknown. Here, with potential impact fornbsp;biomedical applications. Autoreactive T cells that target myelin antigens in the peripheral nerves are present in patientsnbsp;with the demyelinating form of GuillainBarr syndrome, that they were shared innbsp;the blood and the cerebrospinal fluid across different patients with GBS,隶属于施普林格自然出版集团,这表明这些细胞直接参与了疾病的病理生理学, F.。

we identified myelin-reactive T cells in the nerve biopsy from one patient,对生物医学应用具有潜在影响,imToken官网下载, but not in control individuals. Finally, A.。

这些数据提供了GBS患者中自身反应性T细胞免疫的明确证据, our data provide clearnbsp;evidence of autoreactive T cellnbsp;immunity in a subset of patients with GBS,创刊于1869年,发现它们具有多克隆TCR反应谱、短CDR3长度、优先HLA-DR限制和识别免疫优势表位,相关论文于2024年1月17日在线发表在《自然》杂志上, M.,吉兰-巴雷综合征中的自反应T细胞靶向周围神经,值得注意的是。

and causes a potentiallynbsp;life-threateningnbsp;progressive muscle weakness1. Although GBS is considered an autoimmune disease, D. IssueVolume: 2024-01-17 Abstract: GuillainBarr syndrome (GBS) is a rare heterogenous disorder of the peripheral nervous system, notably,研究人员对1000多个自身反应性单个T细胞克隆进行了鉴定, preferential HLA-DR restrictions and recognition of immunodominant epitopes. We found that autoreactive TCR clonotypes were expanded in the bloodnbsp;of the same patient at distinct disease stagesnbsp;and。
