This paper develops an automated assay to quantify synuclein aggregate formation in human dopaminergic neurons using pS129-syn as a marker, showing dose- and time-dependent increases with PFFs and genetic factors affecting aggregate formation.

The paper describes a high-content imaging assay to screen small molecules that reduce cellular uptake of α-synuclein preformed fibrils in hiPSC-derived cells, identifying compounds that effectively lower intracellular PFF load.

The paper shows that combining α-synuclein fibrils with immune challenges causes Lewy body-like inclusions in human dopaminergic neurons, while cortical neurons do not form such inclusions.

This study shows that lysosomal storage diseases cause synaptic structure and neurotransmission defects before cognitive symptoms appear in mice and humans.
