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.

Cracking the code of the extracellular matrix

Despite evidence for a role in plasticity and other crucial functions, many neuroscientists still view these proteins as “brain goop.” The field needs technical advances and a shift in scientific thinking to move beyond this outdated perspective.
