- 生物标志物发现发现
- 神经炎症是一种神经炎症.
背景情况:
- 多发性硬化症 (MS) 的进展与大脑中的先天性免疫细胞激活有关.
- 基因酶-3样蛋白1 (CHI3L1) 是由大脑的质细胞 (星细胞和微质细胞) 表达的.
- 在MS中燃烧的炎症可以使用18kDa转位蛋白 (TSPO) 定子发射断层扫描 (PET) 来评估.
研究的目的:
- 研究MS患者血CHI3L1水平与大脑神经炎症之间的关联.
- 确定CHI3L1是否可以作为MS进展和相关大脑变化的生物标志物.
主要方法:
- 该研究包括55名多发性硬化患者 (25名进展性多发性硬化,30名复发性复发性多发性硬化) 和17名健康对照.
- 使用ELISA测量了CHI3L1等离子体.
- TSPO-PET成像 ([11C]PK11195) 和MRI在一个子队列中进行,以评估大脑炎症和体积.

Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
