Altered insulin signaling and neuroinflammation are emerging features of Alzheimer's disease. Lourenco et al. (2013) identify a pathogenic mechanism that is shared between Alzheimer's disease and diabetes and contributes to memory loss through a common molecular event: the control of protein synthesis by PKR and the downstream phosphorylation of eIF2α.
胰岛素信号改变和神经炎症是阿尔茨海默病的新特征。Lourenco 等人(2013 年)确定了一种在阿尔茨海默病和糖尿病之间共享的致病机制,该机制通过一个共同的分子事件导致记忆丧失:PKR 对蛋白质合成的控制和 eIF2α 的下游磷酸化。
