Research Interests

Dr. Stefanis is investigating various areas of PD pathogenesis, ranging from the bench to the bedside.  He is examining the genetic underpinnings of the disease in the Greek population, not only in the rare familial, but also in sporadic cases. He is involved in studies that aim to examine the utility of using alpha-synuclein as a disease biomarker.  He is examining pathways of neurotoxicity induced by aberrant alpha-synuclein, with an emphasis on the involvement of protein degradation pathways, such as Chaperone-Mediated Autophagy.  He is also investigating the molecular underpinnings of the link of other genetic alterations linked to PD, such as those in UCH-L1, LRRK2 and GBA. He is using a wide array of approaches, ranging from cellular and animal models to studies of patients’ biological material.
