Aβ-Induced Repressor Element 1-Silencing Transcription Factor (REST) Gene Delivery Suppresses Activation of Microglia-Like BV-2 Cells. Neural Plast. 2020;2020:8888871 Authors: Yu T, Quan H, Xu Y, Dou Y, Wang F, Lin Y, Qi X, Zhao Y, Liu X Abstract Compelling evidence from basic molecular biology has demonstrated the crucial role of microglia in the pathogenesis of Alzheimer's disease (AD). Microglia were believed to play a dual role in both promoting and inhibiting Alzheimer's disease progression. It is of great significance to regulate the function of microglia and make them develop in a favorabl...

In this study, we used UPLC-MS to generate a chromatographic fingerprinting of BTF and identified five possible active ingredients, including stilbene glycoside; epimedin A1, B, and C; and icariin. We also showed that oral administration of BTF reversed the cognitive defects in an Aβ 1-42 fibril-infused rat model of AD, protected synaptic ultrastructure in the CA1 region, and restored the expression of BDNF, synaptotagmin (Syt), and PSD95. These effects likely occurred through the BDNF-activated receptor tyrosine kinase B (TrkB)/Akt/CREB signaling pathway. Furthermore, BTF exhibited no short-term or chronic toxicity i...

Abstract As the global population ages, the incidence of neurodegenerative diseases has risen. Furthermore, it has been suggested that depression, especially in elderly people, may also be an indication of latent neurodegeneration. Stroke, Alzheimer's disease (AD), and Parkinson's disease (PD) are usually accompanied by depression. The urgent challenge is further enforced by psychiatric comorbid conditions, particularly the feeling of despair in these patients. Fortunately, as our understanding of the neurobiological substrates of maladies affecting the central nervous system (CNS) has increased, more therapeutic ...

Abstract Objectives: Retina abnormalities are related to cognitive disorders in patients with Alzheimer's disease (AD). Retinal amyloid beta (Aβ) can be labeled by curcumin. We measured Aβ content in the cerebrum and retina of APPswe/PS1dE9 (APP) transgenic mice with early age to investigate the correlation between cerebrum and retina. Methods: APP mice and age-matched wild-type mice were investigated every month from age 2 months to 6 months to assess changes in Aβ content in the retina and cerebrum. At the beginning of each month, mice were fed a curcumin diet (50 mg/kg/day) for 7 cons...

CONCLUSION: Our data suggest that these two polymorphisms do not contribute to AD in the population from the Mersin region of the Eastern Mediterranean. Further studies with larger sample sizes must be conducted to ascertain the association between the 2 polymorphisms. PMID: 33031695 [PubMed - as supplied by publisher]

Kathy Siggins and Lynda Everman are thrilled to share the welcome news that the US Postal Service has reinstated sales of the Alzheimer’s Disease Research Semipostal Stamp effective October 5, 2020. It is now available for purchase at most post offices and online at https://store.usps.com/store/product/buy-stamps/alzheimers-S_564204, and by phone at 1-800 STAMP-24. Before it was withdrawn in November 2019, over 8.2 million stamps were sold during its two-year run raising $1,061,777 for NIH-supported research to advance better treatments, prevention, and one day, a cure of Alzheimer’s and related dementias. The ...

This study sought to investigate what could be learned from how these men have fared. The men were born in 1925-1928 and similar health-related data from questionnaires, physical examination, and blood samples are available for all surveys. Survival curves over various variable strata were applied to evaluate the impact of individual risk factors and combinations of risk factors on all-cause deaths. At the end of 2018, 118 (16.0%) of the men had reached 90 years of age. Smoking in 1974 was the strongest single risk factor associated with survival, with observed percentages of men reaching 90 years being 26.3, 25.7, ...

The big question regarding Alzheimer's disease has always been why only some people suffer this form of dementia. While being overweight clearly increases the risk of dementia, and it is easy to argue that this is because of the chronic inflammation generated by visceral fat tissue, not every overweight individual progresses to the point of Alzheimer's disease. Some people who are not overweight suffer Alzheimer's disease. The condition starts with rising levels of amyloid-β aggregates forming in the brain, thought to be a progressive process occurring over a decade or more prior to any clinical symptoms, but why does...

Conclusions OCB are important biomarkers that can support MRI diagnostics and help to avoid false-positive MS diagnoses. Therefore, the revised McDonalds criteria have increased the importance of the OCB. New biomarkers such as AQP4 have now established themselves in clinical practice, and others such as Anti-MOG and NfL are about to enter clinical routine. An important focus in the search for new biomarkers is the monitoring of therapy efficacy and the prediction of severe side effects. Many other CSF molecules such as CHI3L1, IL-6, or CXCL13 show potential as markers for clinical practice, but further research is nee...
