The BACE1 inhibitor LY2886721 improves diabetic phenotypes of BACE1 knock-in mice

The ?-site amyloid precursor protein (APP) cleaving enzyme 1 (BACE1) has been identified as the central initiator of ? (A?) generation in brain, key hallmark Alzheimer's disease (AD). However, recent studies provided evidence that BACE1 also plays a crucial role metabolic regulation, and we have shown neuronal human knock-in mice (PLB4) display type 2 diabetes mellitus (T2DM)-like symptoms alongside AD-like impairments. Hence, here investigated if targeted inhibition using LY2886721, an active site inhibitor, would improve glucose homeostasis, insulin sensitivity motor performance PLB4 mice. LY2886721 was administered dietary supplement (0.02% wt/wt) for six consecutive weeks. Physiological, assessments were performed during last two weeks treatment, followed by molecular tissue analyses post-mortem. treatment improved homeostasis hepatic gluconeogenesis diabetic mice, determined improvements basal glucose/pyruvate tolerance tests. Furthermore, sensitivity, indicated enhanced hyperphosphorylation receptors. In brains, detected altered conditions APP expression processing, with beneficial effects on processing achieved treatment. No coordination found. Our data provide support regulator systemic suggest inhibitors T2DM-associated pathologies, especially cases where is comorbid to AD. • Strong associations exist between Alzheimer’s (AD) Type Diabetes Mellitus (T2DM). Neuronal resulted AD T2DM phenotype (PLB4 mouse). inhibitor had strong control may be connection T2DM.
