研究興趣 | Research Interests

Biochemical and biophysical studies on misfolding of prion proteins.
Nanoimaging of prion fibrils.

Prion diseases are progressive neurodegenerative disorders that affect both humans and animals, such as Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (mad cow disease) in cows and Scrapie in sheep. Up to date, there is no therapeutic treatment to control or to cure prion diseases. Prion diseases are caused by accumulation of prion amyloid fibrils resulted from misfolding of normal α-helix rich prion proteins into β-sheet rich prion proteins. How prion monomers misfold and convert to fibrils is not know yet. We are interested in studying the mechanism of the prion fibril formation by molecular spectroscopy and nanoimaging.
