About Our Lab
The Mazzulli Lab is interested in determining how protein misfolding and amyloid formation results in cell death. Many chronic neurodegenerative disorders such as Parkinson’s and Alzheimer’s disease are characterized by the accumulation of misfolded proteins within the nervous system. We use patient neurons derived from induced pluripotent stem cells (iPSC) coupled with analytic biochemical techniques to study protein accumulation and lysosomal clearance mechanisms.
