Betaine attenuates Alzheimer-like pathological changes and memory deficits induced by homocysteine.

Hyperhomocysteinemia (Hhcy) may induce memory deficits with β-amyloid (Aβ) accumulation and tau hyperphosphorylation. Simultaneous supplement of folate and vitamin B12 partially restored the plasma homocysteine level and attenuated tau hyperphosphorylation, Aβ accumulation and memory impairments induced by Hhcy. However, folate and vitamin B12 treatment have no effects on Hhcy which has the met...

Hypercholesterolemia accelerates amyloid β-induced cognitive deficits.

Hypercholesterolemia is a known risk factor for Alzheimer's disease (AD). In the present study, we investigated whether diet-induced hypercholesterolemia affects AD-like pathologies such as amyloid β-peptide (Aβ) deposition, tau pathology, inflammation and cognitive impairment, using an Aβ25-35-injected AD-like pathological mouse model. Hyperchole...

Intracerebroventricular Injection of Amyloid-β Peptides in Normal Mice to Acutely Induce Alzheimer-like Cognitive Deficits.

Amyloid-β (Aβ) is a major pathological mediator of both familial and sporadic Alzheimer's disease (AD). In the brains of AD patients, progressive accumulation of Aβ oligomers and plaques is observed. Such Aβ abnormalities are believed to block long-term potentiation, impair synaptic function, and induce cognitive deficits. Clinical and experimental evidences have revealed that the acute increas...

Allicin attenuates tunicamycin-induced cognitive deficits in rats via its synaptic plasticity regulatory activity

Objective(s): To illuminate the functional effects of allicin on rats with cognitive deficits induced by tunicamycin (TM) and the molecular mechanism of this process. Materials and Methods: 200–250 g male SD rats were divided into three groups at random: control group (n=12), TM group (5 μl, 50 μM, i.c.v, n=12), and allicin treatment group (180 mg/kg/d with chow diet, n=12). After 16 weeks of a...

Aminostyrylbenzofuran Directly Reduces Oligomeric Amyloid-β and Reverses Cognitive Deficits in Alzheimer Transgenic Mice

Alzheimer's disease is an irreversible neurodegenerative disorder that is characterized by the abnormal aggregation of amyloid-β into neurotoxic oligomers and plaques. Although many disease-modifying molecules are currently in Alzheimer clinical trials, a small molecule that inhibits amyloid-β aggregation and ameliorates the disorder has not been approved to date. Herein, we report the effects ...
