Neurobiology of Disease: Phosphorylated-tau Associates with HSV-1 Chromatin and Correlates with Nuclear Speckles Decondensation in Low-Density Host Chromatin Regions

Leonardo D'Aiuto, PhD

Abnormal tau phosphorylation is a key pathophysiological mechanism in neurodegenerative diseases. In addition to genetic and environmental factors, infectious agents, such as Herpes Simplex Virus 1, may be associated with the onset or progression of neurodegenerative diseases, including Alzheimer's disease. However, outstanding questions remain regarding the contribution of viruses in the etiology of...

JAMA Psychiatry: Genetic Variants Are Associated with Risk for Bipolar Disorder

Birmaher et al. JAMA Psychiatry 2021

Bipolar disorder (BD) is a familial illness that is associated with functional impairment and increased risk for suicide and substance use. The disorder is highly heritable, and research has identified many common genetic variants associated with risk for the disorder. Studies including the Pittsburgh Bipolar Offspring Study (BIOS) have found that offspring of parents with BD are at elevated, specific risk to...

Now in Journal of Clinical Sleep Medicine: New Research on Insomnia in Older Adults

Wilkens & Colleagues Journal of Clinical Sleep Medicine 2020

Many older adults experience sleep difficulties associated with insomnia. Difficulties with staying asleep are thought to arise partially from reduced sleep depth. Sleep depth can be operationalized as low frequency slow-wave (.5-4 Hz) electroencephalographic (EEG) activity during sleep. However, studies to date have not shown a consistent pattern of EEG differences between individuals with and without insomnia...
