- Many genes in the endolysosomal pathway are genetically linked to Parkinson's disease. We are investigating several genes that function in synaptic vesicle endocytosis.
- Synuclein null synapses showing a deficit in HRP-cholera toxin positive vesicles (black vesicles). This experiment in synuclein null neurons supports a physiological role for alpha-synuclein in synaptic vesicle endocytosis.
