Research activities in the field of Parkinson’s Disease

        I started my work in the field of biophysics of amyloidogenic protein α-synuclein in 2009 during my first postdoctoral training in the lab of Thomas Jovin.  I was investigating the membrane binding of this protein and found dependence of its conformation on the protein density on model membranes.

        When I moved to the Vinod Subramaniam’s group I shifted my research interest and focused on properties and conformation changes of α‑synuclein upon binding to membranes and on oligomeric intermediates of α‑synuclein amyloid fibril formation. The main result of this work was finding of a short domain in α-synuclein sequence that determines equilibrium between membrane-bound helical conformation and formation of amyloid fibrils. (Shvadchak and Subramaniam, Biochemistry, 2014)

        In AMOLF institute I worked on the mechanism of amyloid fibril growth studying the binding of α‑synuclein monomers to the ends of amyloid fibrils using biophysical and structural methods.  The main result of this work was determination of the mechanism of autocatalytic reaction acceleration and quantitative description of the α-synuclein fibril formation kinetics. (Shvadchak et al, J.Phys Chem.B, 2015)

In 2015, I joined a new group established at the IOCB and focused my research on the development of inhibitors of α-synuclein fibrillization based on my expertize in the mechanistic aspects of this process. (Kyriukha et al, J Med Chem, 2019; Shvadchak et al, Angew Chem, 2018)

In 2021, I received a teaching position at Vasyl Stefanyk Precarpathian National University (Ukraine) where I am going to continue development of α-synuclein fibrillization inhibitors with stronger attention to the delivery and activity in animal models.
