Amyloid Fibril Polymorphism : Structure, Supramolecular Chiraliy And Spontaneous Interconversion, Dzmitry Kurouski

Legacy Theses & Dissertations (2009 - 2024)

Specific protein aggregation has been linked to more than 25 severe human maladies including prion, Alzheimer's, and Parkinson's diseases. These important malfunctions are often referred to as 'conformational' disorders and result from the conversion of a normal isoform of a protein into a specific b-sheet rich polymeric amyloid form. This work elaborates a comprehensive characterization of amyloids and dedicated to the investigation of the fibril polymorphism using advanced microscopic tools, such as Atomic Force and Scanning Electron microcopies, together with several vibrational spectroscopy techniques, such as Raman, Infrared and Vibrational Circular Dichroism. A new type of protein folding-aggregation phenomenon, spontaneous …
