- 遗传学
背景情况:
- 骨髓质细胞对于牙质形成 (骨髓生成) 是至关重要的.
- 在自身免疫多腺综合征类型-1 (APS-1) 和腹腔疾病中出现形成缺陷,但机制尚不清楚.
- 原不完善是一种由原蛋白衍生的缺陷引起的先天性疾病.
研究的目的:
- 研究APS-1和腹腔疾病的牙缺陷背后的机制.
- 识别参与质形成中断的自身抗体.
- 建议对这些自身免疫性疾病进行新的分类.
主要方法:

- 研究AIRE (自身免疫调节剂) 在自我耐受性中的作用.
- 在自身免疫中研究耐受性机制 (中央和外围).
主要成果:
- 大多数APS-1和腹腔疾病患者会对乳腺细胞特异性蛋白产生IgA自身抗体.
- 在APS-1中AIRE缺乏导致中央耐受性和自身抗体生成的破坏.
- 在腹腔疾病中,对共享的肠道和面膜抗原的周围耐受性分解驱动自身抗体的产生.
结论:
- 发现了一种新的IgA依赖的自身免疫性疾病,即自身免疫性免疫不完善.

Autoimmune Disorders
449
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.

iPS Cell Differentiation
2.7K
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Gastritis-II: Pathophysiology
346
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...
