Extracellular space diffusion modelling identifies distinct functional advantages of archetypical glutamatergic and GABAergic synapse geometries
onWe modelled extracellular diffusion in super-resolved images of live brain tissue neuropil. We found that extracellular space geometry shapes local diffusion and this has functional implications for signaling arising from synaptic spill-over.

Elevated phosphorylated α-synuclein and phosphorylated tau in Lrrk2 p.G2019S-mutant mice following influenza A pneumonitis
onInfluenza virus infection does not alter acute sickness in mice with Lrrk2 mutations. Surviving Lrrk2 p.G2019S KI mice, however, had elevated oxidative stress and phosphorylated a-synuclein and tau proteins in their brains six weeks post-infection.
