Insulin resistance is one of the metabolic pathogenesis of Type 2 diabetes mellitus which cause neurodegeneration, due to its effects on insulin signaling pathway. The present study focused on the intracerebroventricular administration of streptozotocin (STZ) to induce insulin resistance directly in brain, accounting for alteration in insulin signaling pathway and thus the possible therapeutic effect of Cinnamomum Zeylanicum on the impairment hippocampus of diabetic r...

Aim: We explored the mechanistic interactions and potential therapeutic benefits of curcumin and quercetin co-administration with a specific focus on Glycogen synthase kinase 3 GSK-3 activity.Methods: We hypothesize that excess GSK-3 accumulation in the substantia nigra is driven by oxidative stress and aim to test the effects of these compounds on the localization and activity of GSK-3 in the well-established model organism Drosophila melanogaster. We p...

The hippocampus is majorly involved in memory formation. The insulin pathway regulates the level of GSK-3β, which is involved in the formation of amyloid beta and Tau. Allium sativumhas been shown to reduce amyloidogenesis and increase brain insulin sensitivity. 32 male Wistar rats were used in this experiment. They were grouped into 4, each with 8 rats. Group A (Sham), B (3 mg/kg of streptozotocin), group C (3 mg/kg of streptozotocin +300 mg/kg of Allium sat...

Alzheimer’s disease (AD) development has a direct relationship with Brain-insulin resistance. Central in the pathology of AD are beta-amyloid and tau proteins associated with cognitive decline in the hippocampus. Allium sativum L. has been shown to have a neuroprotective effect. Thirty-two male Wistar rats (80-150 g) were assigned into A-D (n=8 each), and housed in standard plastic cages at 23± 1°C. Group A received saline, groups B and C were ad...

Cognitive impairment and neurodegeneration are a few hallmarks of brain insulin resistance, a core feature of Type 2 diabetes mellitus (T2DM). Using a Wistar rat model of a high-fat diet and streptozotocin-induced T2DM, we aimed to determine the potential of Vernonia amygdalina (VA) as a possible treatment for the accompanied neurodegenerative effects of this condition on hippocampal structure and function. T2DM adult rats were prepared by a combination of a high-fat diet and ...
