Structure And Stability Of Amyloid Fibrils Studied By Advanced Vibrational Spectroscopy, Marudachalam Shanmugasundaram

Legacy Theses & Dissertations (2009 - 2024)

Protein misfolding often leads to the formation of refractory protein aggregates like amyloid fibrils. These fibrils possess a highly ordered structure and are implicated in over 25 severe diseases including Alzheimer’s, Parkinson’s and prion diseases. This work was focused on understanding the morphology and conformation of amyloid fibrils and their stability after formation. The deconstruction of fibrils as well as other aggregates like inclusion bodies under mild conditions was also investigated using Archaeal chaperones.

Legacy Theses & Dissertations (2009 - 2024)

Amyloid aggregation is a specific form of protein misfolding and self-assembly related to several degenerative pathologies like Alzheimer's and Parkinson's diseases, type-II diabetes, etc. This association with deadly diseases has made amyloid fibrils the focus of intensive research for many decades. Most recently, a significant interest to protein fibrils was also due to the application of the remarkable self-assembling capabilities to form well-structured nano-biomaterials. Self-assembly of short peptide sequences into well-organized structures is another important strategy for bottom-up fabrications of nano-biomaterials. One of the most commonly used building blocks is diphenylalanine, a short dipeptide that has been identified as playing …
