Description:	NIH Neuroscience Series Seminar. Dr. Volpicelli-Daley discovered that exposure of neurons to seeds of amyloid fibrils composed of alpha-synuclein causes endogenous alpha-synuclein to form aggregates that morphologically and biochemically resemble those found in Parkinson's disease. The goal of the lab is to stop this pathogenic templating of alpha-synuclein to halt the progression of Parkinson’s disease. The lab also seeks to understand the neurobiologic mechanisms by which alpha-synuclein aggregates cause neuron dysfunction. We have several projects in the lab. We are determining how LRRK2, the most common genetic cause of Parkinson's disease, impacts trafficking of alpha-synuclein to the presynaptic terminals. We are also determining how genes implicated in PD increase cognitive dysfunction. The lab utilizes biochemical techniques to identify novel proteins and protein interactions involved in alpha-synuclein aggregate formation. The lab performs super-resolution microscopy to image protein localization at nanoscale resolution. We perform live cell imaging in neurons to measure calcium transients and axonal transport. We use rodent models to determine the impact of PD genes on behavior. Finally, Dr. Volpicelli-Daley is dedicated to the success of graduate and undergraduate students in the lab that have received prestigious fellowships awards, and have successful publishing records.

Abstract:	(CIT): NIH Neuroscience Series Seminar. Dr. Volpicelli-Daley discovered that exposure of neurons to seeds of amyloid fibrils composed of alpha-synuclein causes endogenous alpha-synuclein to form aggregates that morphologically and biochemically resemble those found in Parkinson"s disease. The goal of the lab is to stop this pathogenic templating of alpha-synuclein to halt the progression of Parkinson"s disease. The lab also seeks to understand the neurobiologic mechanisms by which alpha-synuclein aggregates cause neuron dysfunction. We have several projects in the lab. We are determining how LRRK2, the most common genetic cause of Parkinson"s disease, impacts trafficking of alpha-synuclein to the presynaptic terminals. We are also determining how genes implicated in PD increase cognitive dysfunction.
