概括

氧化 (NO) 可以防止实验性自身免疫脑膜炎 (EAE). 在诱导过程中调节NO水平可以改变动物的EAE易受性,从而影响T细胞迁移.

科学领域:

神经免疫学神经免疫学
自免疫性研究的研究.

背景情况:

实验性自身免疫脑膜炎 (EAE) 的严重程度因动物菌株和性别而异,当与神经抗原在完整的弗洛恩德辅助剂 (CFA) 中诱导时.
碳酸铁作为辅助剂使所有动物菌株对EAE敏感,与CFA不同.

研究的目的:

调查是否过度的氧化 (NO) 生产可以防止自身免疫.
为了确定诱导期间的NO水平是否会影响EAE易感性.
探索操纵NO度是否可以赋予对EAE的抗性.

主要方法:

使用完整的弗洛恩德辅助剂 (CFA) 与碳酸铁进行EAE诱导的比较.
诱导性氧化合成酶 (iNOS) 在EAE耐药和敏感菌株中的表达的分析.
审查NO在调节T细胞在EAE诱导过程中的行为中的作用.

主要成果:

完整的弗洛恩德辅助剂 (CFA) 在耐EAE菌株中诱导高水平的可诱导氧化合成酶 (iNOS).
在诱导阶段修改NO度可以改变耐药和敏感的动物株的EAE易感性.
氧化 (NO) 诱导脑原性T细胞中的actin两极化,减少它们的跨内皮迁移.

结论:

过度的氧化 (NO) 生产可以防止EAE等自身免疫的发展.
在诱导阶段干扰NO度可以使不敏感的菌株变得敏感,而敏感的菌株则对EAE产生抵抗力.
在T细胞中,NO介导的动因两极化是减少它们迁移并保护它们免受EAE的关键机制.

Nitric Oxide Signaling Pathway

Nitric Oxide Signaling Pathway

Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Encephalitis l: Introduction

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
