Abstract

See Cunha (doi:10.1093/brain/awz335) for a scientific commentary on this article. Carvalho et al. provide clues to the onset of immune dysregulation underlying early synaptic loss in Alzheimer’s disease and tauopathies, by linking overactivation of adenosine A2A receptors in tau pathology to a particular microglial signature (upregulation of C1q and TREM2) allied to the loss of glutamatergic synapses and cognitive deficits.
