Type 2 diabetes is a risk factor for Alzheimer's disease and Parkinson's disease. Insulin signaling in the brains of people with Alzheimer's disease or Parkinson's disease is impaired. Preclinical studies of growth factors showed impressive neuroprotective effects. In animal models of Alzheimer's disease and Parkinson's disease, insulin, glia-derived neurotrophic factor, or analogues of the incretin glucagon-like peptide-1 prevented neurodegenerative processes and improved neuronal and synaptic functionality in Alzheimer's disease and Parkinson's disease. On the basis of these promising findings, several clinical trials are ongoing with the first encouraging clinical results published. This gives hope for developing effective treatments for Alzheimer's disease and Parkinson's disease that are currently unavailable.
2型糖尿病是阿尔茨海默病和帕金森病的一个风险因素。阿尔茨海默病或帕金森病患者大脑中的胰岛素信号传导受损。生长因子的临床前研究显示出显著的神经保护作用。在阿尔茨海默病和帕金森病的动物模型中,胰岛素、胶质细胞源性神经营养因子或肠促胰岛素胰高血糖素样肽-1的类似物可预防神经退行性过程,并改善阿尔茨海默病和帕金森病中的神经元及突触功能。基于这些有前景的发现,目前正在进行多项临床试验,并且已经公布了首批令人鼓舞的临床结果。这为开发目前尚无的针对阿尔茨海默病和帕金森病的有效治疗方法带来了希望。
