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.

Single-cell genomics technologies and cell atlases have ushered in a new era of human neurobiology

Single-cell approaches are already shedding light on the human brain, identifying cell types that are most vulnerable in the early stages of Alzheimer’s disease, for example.

Huntington’s disease gene variants past a certain size poison select cells

The findings—providing “the next step in the whole pathway”—help explain the disease’s late onset and offer hope that it has an extended therapeutic window.

Brains, biases and amyloid beta: Why the female brain deserves a closer look in Alzheimer’s research

New results suggest the disease progresses differently in women, but we need more basic science to unpack the mechanisms involved.

Supersized version of Alzheimer’s protein avoids clumping in brain

“Big tau” may explain why some brain regions, such as the cerebellum and brainstem, are largely spared from neurodegeneration, even though tau is expressed throughout the nervous system.
