Scientists Identify New Targets to Stop the Progression of Alzheimer's Disease

It is necessary to identify new therapeutic targets to stop the progression of Alzheimer's disease in the early stage.

Prof. Yunpeng Cao and team from the First Affiliated Hospital of China Medical University examined striatal-enriched phosphatase 61 expression in the brain tissues of Alzheimer's disease rats using in vivo and in vitro models, and analyzed the molecular mechanism by which striatal-enriched phosphatase 61 regulates N-methyl-D- aspartate receptor 2B transport. The researchers found that valeric acid (AP5), an N-methyl-D-aspartate receptor antagonist, significantly inhibited amyloid- beta 1-induced increased activity of striatal-enriched phosphatase 61.

Alzheimer’s disease - Causes, Symptoms, Diagnosis, Stages, Types, Prevention, Prognosis & Treatment
Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

In addition, the phos-phorylation of N-methyl-D-aspartate receptor 2B at Tyr1472 was impaired in amyloid-beta 1-treated cortical neurons, but knockdown of striatal-enriched phosphatase 61 enhanced the phosphorylation of N-methyl-D-aspartate receptor 2B. Collectively, these findings, published in the Neural Regeneration Research (Vol. 8, No. 21, 2013), indicate that striatal-enriched phosphatase 61 can disturb N-methyl-D-aspartate receptor transport and inhibit the progression of learning and study disturbances induced by Alzheimer's disease. Thus, striatal-enriched phosphatase 61 may represent a new target for inhibiting the progression of Alzheimer's disease.

Risk Factors for Alzheimers Disease
Cognitively normal adults exhibiting atrophy of their temporal lobe or damage to blood vessels in the brain are more likely to develop Alzheimer’s disease.

Does Obesity in Old Age Cause Memory Problems?
The American Academy of Neurology have confirmed that being overweight in old age does not lead to memory problems but contributes to high blood pressure, heart disease and diabetes.

Smokers are at Risk of Alzheimer's Disease
People who smoke are at a greater risk of developing Alzheimer's disease and other forms of dementia.
