Research interest

           Protein misfolding and aggregation are a hallmark of various human diseases including several aging diseases such as Alzheimer's disease and type-II diabetes. The molecular basis of protein misfolding and aggregation and their pathological effects are poorly understood due to the involvement of a complex cellular pathway. Several cellular co-factors are known to modulate such protein aggregation including cell-membrane. In this lab, we are using peptide- or polymer-encapsulated lipid-nanodiscs as a model membrane system to explore the role of cell-membrane in modulating protein aggregation. We are employing an integrated experimental and computational approach that includes neuroscience, chemical biology, and structural biology to disclose the structural basis of amyloid formation in a complex cellular environment. The research findings could aid in the development of potential therapeutic strategies against several unnerving human diseases.
