Protein misfolding and aggregation into amyloid fibers happens during aging and cause diseases like Alzheimer's (AD), Parkinson's ( PD ) and Type 2 Diabetes ( T2D ). Among numerous intrinsic and extrinsic factors that modulate the protein aggregation, cell-membrane is strongly associated with the pathogenesis of these diseases. We, therefore, would like to explore the molecular mechanism of such aggregation at atomistic scale using lipid-nanodiscs that provides a native membrane-mimetic model environment. We are integrating a variety of advanced biophysical and computational approaches to tracking the dynamic structural changes of two major amyloidogenic peptides amyloid-beta ( Aβ ) and Islet amyloid polypeptide ( IAPP ) that are connected to AD and T2D, respectively. The research findings and the high-resolution structure elucidation will be greatly helpful to develop therapeutic strategies not only for AD and T2D but also for several devastating neurodegenerative diseases in which amyloids are involved.
