Structural basis of a distinct α-synuclein strain that promotes tau inclusion in neurons.

ABSTRACT: Amyloidoses are predominantly associated with the accumulation of persistent aggregates of a particular protein. For example, the protein α-synuclein characteristically aggregates in Parkinson's disease (PD), while amyloid beta and tau deposits are associated with Alzheimer's disease (AD). However, α-synuclein-positive inclusions have been reportedly found in some tauopathies, and vice versa; tau-positive inclusions can be found in synucleinopathies. This suggests that there may be coexistence or crosstalk between these proteinopathies. This coexistence suggests that the simultaneous presence of these misfolded proteins may amplify pathogenic mechanisms. However, the crosstalk between these two types of proteopathies remains poorly understood. We now determine the structure of α-synuclein
