There is evidence from in vitro experiments that dipeptidyl peptidase IV (DPP IV) might play role(s) in amyloid formation. However, nothing is known about the localization of the enzyme in brains of individuals with Alzheimer's disease. We herein show that in comparison to non-demented controls DPP IV is upregulated in AD brain neurons and occurs in multiple amyloid plaques.
有体外实验证据表明二肽基肽酶 IV(DPP IV)可能在淀粉样蛋白形成中起作用。然而,目前尚不清楚这种酶在阿尔茨海默病患者大脑中的定位。本文显示,与非痴呆对照相比,DPP IV 在 AD 大脑神经元中上调,并存在于多个淀粉样斑块中。
