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。
