Everything, everywhere, all at once: Inside the chaos of Alzheimer’s disease

To truly understand Alzheimer’s disease, we may need to take a systems approach, in which inflammation, vascular injury, impaired glucose metabolism and other factors interact in complex ways.

Plaque levels differ in popular Alzheimer’s mouse model depending on which parent’s variants are passed down

5XFAD model mice that inherit two disease-related genes from their fathers have double the plaques seen in those with maternal inheritance, a new study shows.

Putting a bright idea to the test

A surprising wave of findings in mice suggests that light and sound flickering at 40 hertz clears the brain of Alzheimer’s-disease-linked plaques. Several companies are hoping to prove it works in people.

Null and Noteworthy: Neurons tracking sequences don’t fire in order

Instead, neurons encode the position of sequential items in working memory based on when they fire during ongoing brain wave oscillations—a finding that challenges a long-standing theory.

How to teach this paper: ‘Neurotoxic reactive astrocytes are induced by activated microglia,’ by Liddelow et al. (2017)

Shane Liddelow and his collaborators identified the factors that transform astrocytes from their helpful to harmful form. Their work is a great choice if you want to teach students about glial cell types, cell culture, gene expression or protein measurement.
