Basic Science and Pathogenesis.

Background: Tau aggregates, a hallmark of Alzheimer's disease (AD) and other tauopathies, spread throughout the brain, contributing to neurodegeneration. How this propagation occurs remains elusive. Previous research suggests that tau-seed interactors play a crucial role.

Basic Science and Pathogenesis.

Background: Tau aggregation is the major cause of several neurodegenerative tauopathies. Tau interaction with other proteins affects the formation of tau aggregates with seeding activity but less is known about its effects on tau-seed properties. Our previous study revealed that Bassoon (BSN), a presynaptic protein, interacts with tau-seed, exacerbating its toxicity in vivo.

Changes in US drinking and alcohol use disorders associated with social, health, and economic impacts of COVID-19.

Aims: The COVID-19 pandemic increased alcohol consumption in the USA as a result of widespread individual changes in drinking patterns. Few studies have utilized longitudinal data allowing the prediction of increased or decreased drinking from COVID-19 economic, social, and health impacts.

Methods: Data are from 1819 respondents in the 2019-20 National Alcohol Survey and a one-year follow-up in early 2021.

MirGeneDB 3.0: improved taxonomic sampling, uniform nomenclature of novel conserved microRNA families and updated covariance models.

We present a major update of MirGeneDB (3.0), the manually curated animal microRNA gene database. Beyond moving to a new server and the creation of a computational mirror, we have expanded the database with the addition of 33 invertebrate species, including representatives of 5 previously unsampled phyla, and 6 mammal species.
