The Summer Undergraduate Research Fellowship (SURF) Symposium

Parkinson’s Disease (PD) is a common neurodegenerative disease with over 200,000 new cases each year. In general, the cause of the disease is unknown, but oxidative stress inside of neurons has been associated with the disease’s pathology for some time. Currently, techniques to study the onset of PD inside of neurons are limited. This makes treatments and causes difficult to discover. One solution to this has been fluorescent protein biosensors. In short, these proteins can be engineered to glow when a certain state is achieved inside a cell. The present research discusses the engineering of a genetically-encoded ...

The Summer Undergraduate Research Fellowship (SURF) Symposium

Purinergic signaling is a type of extracellular communication that occurs between cells, mediated by adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine. In Parkinson’s Disease, purinergic signaling is disrupted, which contributes to neurodegeneration. In order to monitor this change in cell-to-cell signaling, there is a need for the development of a fluorescent protein (FP) biosensor to study the changes in the concentration of the signaling molecule ATP and its decomposition bioproduct ADP. This summer a genetically encoded ADP sensor that measures changes in ADP concentration was developed. This sensor utilizes Forster Resonance Energy Transfer (FRET) which is a sensing ...
