概括
与健康个体相比,硬化症患者对硬化神经组织抗体的反应性更高. 这一发现可能有助于了解硬化症和相关眼睛疾病的自身免疫基础.
科学领域:
- 眼科医生 眼科 眼科
- 免疫学 免疫学 免疫学
- 这是一种自身免疫力.
背景情况:
- 硬化症是一种严重的,痛苦的眼睛疾病,通常与自身免疫有关.
- 之前的研究表明,原导向的自身免疫在结核病发病过程中起着作用.
研究的目的:
- 在患有非传染性硬化症的患者中检查硬化组织特异性抗体的存在.
- 评估结核自身抗体与结核炎的临床特征之间的关联.
主要方法:
- 一项前性队列研究,涉及121名非传染性硬化症患者,39名健康对照组和48名脑膜炎对照组.
- 通过ELISA对抗原人类II型原蛋白抗体的血清分析.
- 在冷切片上使用间接免疫光学 (IIF) 检测到的结核特异性抗体.
- 人类白细胞抗原 (HLA) 类型测定在硬化症患者身上进行.
主要成果:
- 在结核炎,健康和脑膜炎组中,抗II型原蛋白抗体没有显著差异.
- 在33%的结核炎患者中观察到结核神经组织的反应性,明显高于健康对照 (11%).
- 对缩神经组织的反应性与早期发病,双边疾病和减少缩神经缩有关. 在硬化症患者中,HLA-B27的患病率更高.
结论:
- 对质神经组织的自身抗体反应性在质炎和脑膜炎患者中比在健康人群中更为普遍.
- 这些发现表明,一种潜在的自身免疫机制在结核炎中准结核神经.
- 需要进一步的研究来描述这些抗体及其临床意义.

Autoimmune Disorders
436
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

T Cell Types and Functions
1.0K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Gastritis-II: Pathophysiology
326
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
