Can you catch dementia? Insights and solutions from prion disease

NIH Director's Wednesday Afternoon Lecture Series The Department of Neurodegenerative Disease ’ s research portfolio encompasses prion diseases (predominantly within the embedded MRC Prion Unit), Alzheimer ’ s disease and related disorders, Huntington ’ s disease, motor neurone disease and frontotemporal dementia and studies of the pathways of cellular senescence. The research philosophy is to combine basic and clinical translational research; many of the key contributions towards understanding the basic biology of these diseases have come from clinical and neuropathological observations, and efficient translation of basic laboratory research to the clinic is essential to provide benefits for patients at the earliest opportunity.For more information go tohttps://oir.nih.gov/walsAir date: 12/5/2018 3:00:00 PM

CNS Neurol Disord Drug Targets. 2021 May 26. doi: 10.2174/1871527320666210526160214. Online ahead of print.ABSTRACTAMP-activated protein kinase (AMPK) is a serine/threonine kinase and a driving or deterrent factor in the development of neurodegenerative diseases and dementia. AMPK affects intracellular proteins like the mammalian target of rapamycin (mTOR). Peroxisome proliferator-activated receptor-γ coactivator 1-α (among others) contributes to a wide range of intracellular activities based on its downstream molecules such as energy balancing (ATP synthesis), extracellular inflammation, cell growth, and neuro...

Conclusion The key problem with the ND field is the lack of understanding in the events preceding the development of protein-based markers – such as Tau – currently used to diagnose NDs. By this stage, the diseases become more difficult to treat. SncRNAs play an important regulatory role in the maintenance of the homeostatic brain. Therefore, changes in their concentration levels can be indicative of mechanistic changes that could precede protein-based markers. One single sncRNA biomarker is unlikely to differentiate between diseases. However, a combination of sncRNA biomarkers could be illustrative of the me...

This study was carried out in accordance with the recommendations of the National Animal Care and Use Committee of the University of Buenos Aires (CICUAL). The protocol was approved by the CICUAL. Mice were kept under a 12-h light/dark cycle, with controlled temperature (23 ± 2°C) and humidity (40–60%) and had ad libitum access to food and water. To produce hTDP-43 transgenic lines, as described previously (Igaz et al., 2011), pronucleus of fertilized eggs from C57BL/6J × C3HeJ F1 matings were injected with a vector containing hTDP-43-WT cDNA. Monogenic tetO-TDP-WT12 mice wer...

Conclusions There are very few measures of carer QOL that are specific to particular neurodegenerative diseases. The findings of this review emphasise the importance of developing and validating psychometrically robust disease-specific measures of carer QOL.

Discussion and conclusions Although longitudinal imaging studies have the potential to provide crucial insights into the presymptomatic phase and natural trajectory of neurodegenerative processes a standardised design is required to enable meaningful data interpretation.
