概括
较高的血质纤维酸蛋白 (GFAP) 水平会增加脑炎的风险. 神经退行性痴呆症,如阿尔茨海默氏症,也提高了血GFAP,支持其作为生物标志物的使用.
科学领域:
- 神经学 神经学
- 生物标志物 生物标志物
- 遗传学 遗传学 是一个
背景情况:
- 血液中的状纤维酸蛋白 (GFAP) 表明神经系统疾病中的星病和星细胞损伤.
- 血GFAP与神经疾病之间的因果关系尚未完全理解.
研究的目的:
- 通过双向门德尔随机化 (MR) 来研究血GFAP水平与各种神经疾病之间的因果关系.
主要方法:

Amyloid Fibrils
9.9K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
