Development of an α-synuclein knockdown peptide and evaluation of its efficacy in Parkinson’s disease models

Tat-βsyndegron decreased α-synuclein aggregates and microglial activation in an α-synuclein preformed fibril model of spreading synucleinopathy in transgenic mice overexpressing human A53T α-synuclein. Moreover, Tat-βsyn-degron reduced α-synuclein levels and significantly decreased the parkinsonian toxin-induced neuronal damage and motor impairment in a mouse toxicity model of PD. These results show the promising efficacy of Tat-βsyn-degron in two different animal models of PD and suggest its potential use as an effective PD therapeutic that directly targets the disease-causing process.
