项目摘要

Alzheimer's disease (AD) is an incurable brain disease, distinguished by the progressive accumulation of toxic amyloid and tau protein aggregates that are partly due to impaired waste clearance by the glymphatic and meningeal lymphatic systems. We have recently shown that noninvasive Gamma ENtrainment Using Sensory stimuli (GENUS) to induce neural oscillations in the gamma frequency range (30-90 Hz) could ameliorate pathology in various AD mouse models. Mice subjected to GENUS regime exhibited positive effects on microglia, astrocytes and the brain vasculature as well as reduced accumulation of amyloid and hyperphosphorylated tau in respective amyloid and tauopathy mouse models. However, the impact of GENUS on the glymphatic/lymphatic systems in the clearance of amyloid and tau accumulation is not clear. We will use amyloid and tauopathy mouse models to determine whether and identify the mechanisms by which GENUS enhances paravascular fluid movement and thereby promotes meningeal lymphatic drainage and glymphatic clearance of brain toxic metabolites including those associated with amyloid and tau.

阿尔茨海默氏病（AD）是一种无法治愈的脑疾病，以有毒的逐渐积累为特色淀粉样蛋白和tau蛋白聚集体部分是由于散晶和糖的清除受损而引起的脑膜淋巴系统。我们最近表明，使用感觉的无创伽马夹带刺激（属）诱导伽马频率范围内的神经振荡（30-90 Hz）可以改善各种AD鼠标模型中的病理。受到属状态的小鼠对小胶质细胞表现出积极影响，星形胶质细胞和脑脉管系统以及淀粉样蛋白和高磷酸化TAU的积累降低在各自的淀粉样蛋白小鼠模型中。但是，属对淋巴/淋巴的影响清除淀粉样蛋白和TAU积累的系统尚不清楚。我们将使用淀粉样蛋白和tauopathy 小鼠模型以确定并确定属增强链血管的机制液体运动，从而促进脑膜淋巴引流和脑部有毒的胶囊清除率代谢物，包括与淀粉样蛋白和Tau相关的代谢物。
