The presence of protein aggregates is common in neurodegenerative disorders; however, the real cause and effect of these aggregates during neurodegeneration is still a matter of investigation. We hypothesize that impairment of intracellular traffic may appear in the absence of protein inclusions and might trigger protein aggregation. In the present study,(More)
Protein aggregates containing alpha-synuclein, beta-amyloid and hyperphosphorylated tau are commonly found during neurodegenerative processes which is often accompanied by the impairment of mitochondrial complex I respiratory chain and dysfunction of cellular systems of protein degradation. In view of this, we aimed to develop an in vitro model to study(More)
Neurodegeneration is often accompanied by protein inclusions which may interfere with cell physiology. On the other hand, alteration in intracellular trafficking may precede impairment of neurotransmission and therefore trigger cell death. In view of this, it is hypothesized that changes in mitochondrial traffic may occur before neurodegeneration triggered(More)
The formation of oligomers and aggregates of overexpressed or mutant α-synuclein play a role in the degeneration of dopaminergic neurons in Parkinson’s disease by causing dysfunction of mitochondria, reflected in their disturbed mobility and production of ROS. The mode of action and mechanisms underlying this mitochondrial impairment is still unclear. We(More)
