背景情况:

代谢性疾病 (二型糖尿病,肥胖,代谢综合征) 的增长率与神经退行性疾病的增加并行.
目前的模型缺乏一个统一的框架,将系统代谢功能障碍与大脑病理联系起来.
大脑的共同代谢脆弱性在神经退行研究中经常被忽视.

研究的目的:

为神经退行性疾病提出一个统一的代谢范式.
为了引入胰岛素抵抗-Sirtuin 1 (SIRT1) 崩轴.
将神经退化重新定义为整个大脑的代谢失败.

主要方法:

概念框架的发展.
代谢和神经退行性途径的文学综合.
关于综合多omics和成像验证的建议.

主要成果:

慢性胰岛素抵抗导致神经元SIRT1活性下降.
SIRT1功能障碍会影响细胞能量感知,应激适应和炎症控制.
这个轴将胰岛素抵抗与线粒体衰竭,氧化应激和神经炎症联系在一起.

结论:

胰岛素抵抗-SIRT1轴为神经退行症提供了一个统一的代谢范式.
神经退行可以被视为影响大脑的全身代谢失败.
针对胰岛素敏感性,NAD+恢复和生活方式干预的治疗策略显示出有希望.

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.

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...
