Organisms have evolved mechanisms to cope with and adapt to unexpected challenges and harsh conditions. Unfolded or misfolded proteins represent a threat for cells and organisms, and the deposition of misfolded proteins is a defining feature of many age-related human diseases, including the increasingly prevalent neurodegenerative diseases. These protein misfolding diseases are devastating and ...

Mutations of Cu, Zn‐superoxide dismutase (SOD1) gene have been identified in a subset of familial amyotrophic lateral sclerosis (ALS). Conformational change, that is, misfolding, of mutant SOD1 underlies its toxic gain of function for motor neuronal degeneration. Mutant SOD1 is prone to cause oxidative stress through the copper exposed on the protein by misfolding. The protein structure of SOD1...

Protein misfolding and aggregation into oligomeric fibrillar structures is a common feature of many neurogenerative disorders. Single-molecule techniques have enabled characterization these lowly abundant, highly heterogeneous protein aggregates, previously inaccessible using ensemble averaging techniques. However, they usually rely on the use recombinantly-expressed labeled protein, or additio...

Protein misfolding and aggregation underpin several fatal neurodegenerative diseases, including Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and frontotemporal dementia (FTD). There are no treatments that directly antagonize the protein-misfolding events that cause these disorders. Agents that reverse protein misfolding and restore proteins to native form and function could si...
