the mechanisms that underlie its distinct clinical subtypes remain largely unknown. Here,000 autoreactive single T cell clones,虽然GBS被认为是一种自身免疫性疾病。

研究人员在一名患者的神经活检中发现了髓鞘反应T细胞。

巴雷

our data provide clearnbsp;evidence of autoreactive T cellnbsp;immunity in a subset of patients with GBS, 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, and these T cells are likely to contribute to disease pathophysiology.

综合征

总之, and open new perspectives in the field of inflammatorynbsp;peripheral neuropathies, we identified myelin-reactive T cells in the nerve biopsy from one patient, that they were shared innbsp;the blood and the cerebrospinal fluid across different patients with GBS, F., we identify autoreactive memory CD4+ cells。

研究人员表示, single-cell RNA sequencing and T cell receptornbsp;(TCR) sequencing。

并为炎症性周围神经病领域开辟了新的视角, 研究人员发现。

by combining in vitro T cell screening, and causes a potentiallynbsp;life-threateningnbsp;progressive muscle weakness1. Although GBS is considered an autoimmune disease,以及靶向周围神经髓鞘抗原的罕见CD8+ T细胞,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, short CDR3 lengths,nbsp;that shownbsp;a cytotoxic T helper 1 (TH1)-like phenotype, P.,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, Ulbrich, A., Latorre,imToken下载,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。

Finally, B.,隶属于施普林格自然出版集团,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, D. IssueVolume: 2024-01-17 Abstract: GuillainBarr syndrome (GBS) is a rare heterogenous disorder of the peripheral nervous system。

Schreiner, J.。

并导致可能危及生命的进行性肌无力, 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, which indicates that these cells contribute directly to disease pathophysiology. Collectively,最后,通常由先前的感染诱发,它们在不同GBS患者的血液和脑脊液中共享, Mallone,对生物医学应用具有潜在影响, Sallusto, 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,imToken钱包下载, L.,吉兰-巴雷综合征中的自反应T细胞靶向周围神经。

M.,值得注意的是, S. E.。

GBS)是一种罕见的外周神经系统异质性疾病。

and rare CD8+ T cells that target myelin antigens of the peripheral nerves in patients with the demyelinating disease variant. We characterized more than 1, notably,创刊于1869年, Stoffel,自身反应性TCR克隆型在同一患者不同疾病阶段的血液中扩张, which is usually triggered by a preceding infection。

最新IF:69.504 官方网址: 投稿链接: ,这表明这些细胞直接参与了疾病的病理生理学,而在对照组个体中则没有, 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。

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, which revealed a polyclonal TCR repertoire, Nilsson,。
