概括

淋巴功能障碍,通过神经毒性蛋白质的清除受损而表明,在帕金森病 (PD) 中很普遍. 这种功能障碍与运动症状相关,这表明它有可能成为PD的成像生物标志物.

科学领域:

神经科学是一个神经科学.
放射学放射学是一门学科.
生物标志物发现发现

背景情况:

帕金森病 (PD) 是一种神经退行性疾病,其特点是运动和非运动症状.
缺陷的淋巴清除,对于清除神经毒性蛋白质至关重要,可能在PD的发病过程中发挥作用.
像扩散张力成像-沿周血管空间 (DTI-ALPS) 和扩大周血管空间 (EPVS) 等MRI技术评估淋巴功能.

研究的目的:

评估帕金森病 (PD) 患者的淋巴功能.
评估淋巴功能作为PD的成像生物标志物的潜力.
调查淋巴管功能障碍与PD临床结果之间的关联.

主要方法:

在Web of Science,Scopus和PubMed进行了系统的文献搜索.
分析比较了PD患者 (PwPD) 和健康对照者 (HCs) 之间的淋巴体指数 (DTI-ALPS,EPVS).
效果方向图和元相关性检查了与临床结果和参与者特征的关联.

主要成果:

35项研究包括4224名PwPD和1287名HC.
与HC相比,PwPD的DTI-ALPS数量较低,EPVS数量和数量较高.
淋巴功能障碍与运动症状严重程度相关,但与认知和睡眠有不一致的关联.

结论:

淋巴功能障碍是PD的重要特征,与运动症状相关.
这种功能障碍显示出作为PD生物标志物或治疗点的潜力.
由于测量技术的变化和对非运动症状的不一致发现,需要进一步研究.

关键词:

Parkinson's Disease: Overview

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Neural Regulation

Neural Regulation

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.

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
