Neuronal AIMP2–α-synuclein synergy drives endogenous tau and amyloid-β pathologies and neurodegeneration in a mechanistic model of Lewy body dementia
A genetically controlled in vivo model of LBD-like mixed proteinopathy recapitulating αSyn aggregation, tau hyperphosphorylation, Aβ accumulation, neurodegeneration, and behavioral decline is established and supports a mechanistic link between AIMP2-enhanced αSyn toxicity and secondary proteinopathies.
