Title: DNA-based tools for the study and treatment of Parkinson’s Disease

Description:

Aptamers are short stretches of DNA that fold into 3-dimensional shapes that can act as pockets for binding other biological molecules. This ability to act as an artificial “receptor” makes aptamers useful in many diagnostic and therapeutic applications. This presentation will describe an aptamer system that interacts with a protein known as alpha-synuclein. Alpha synuclein has been implicated in the pathogenesis of Parkinson’s disease, in particular due to its propensity to aggregate to form toxic oligomers and fibrils. Researchers in our group have discovered aptamers that interfere with the aggregation of alpha-synuclein both in vitro and in vivo. In this presentation, we’ll describe the science of aptamers, how the alpha-synuclein aptamers were discovered and characterized, and their applications for the diagnosis, study, and treatment of Parkinson’s disease.
