Sortilin is required for toxic action of Aβ oligomers (AβOs): Extracellular AβOs trigger apoptosis, and intraneuronal AβOs impair degradation pathways

Taken together, these findings provide novel lines of evidence that sortilin governs the toxic action of extracellular AβOs, which affects the degradation and/or clearance of either intraneuronal AβOs or tau. Thus, therapeutic intervention targeting extracellular AβOs themselves or for preventing the interaction between intraneuronal AβOs and tau is a promising strategy to be developed for AD treatment.
