Emerging evidence links type 2 diabetes mellitus (T2DM) and Alzheimer's disease (AD), with brain insulin resistance (BIR) as a key factor. In a recent study, Lanzillotta et al. reveal that reduced biliverdin reductase-A (BVR-A) impairs glycogen synthase kinase 3β (GSK3β) phosphorylation, causing mitochondrial dysfunction and exacerbating brain insulin resistance in the progression of both T2DM and AD.
新的证据表明 2 型糖尿病(T2DM)和阿尔茨海默病(AD)之间存在关联,而大脑胰岛素抵抗(BIR)则是一个关键因素。在最近的一项研究中,Lanzillotta 等人揭示了低水平的胆绿素还原酶-A(BVR-A)会损害糖原合成酶激酶 3β(GSK3β)的磷酸化,导致线粒体功能障碍,并在 T2DM 和 AD 的进展中加剧大脑胰岛素抵抗。
