Hatters laboratory: Protein misfolding and proteostasis in neurodegenerative diseases

Research Overview

Research in the Hatters lab is focused on understanding the molecular mechanisms underpinning neurodegenerative diseases involving protein misfolding and aggregation. This primarily includes Huntington’s and Motor Neuron Diseases.  Our efforts involve building new biosensors and methods to track the misfolded and aggregated states of proteins in cells and using these approaches to determine how they interact with the cellular machinery to propagate dysfunction or trigger adaptive responses to stress.  Other related areas of research include defining the latent efficiency of cells to manage folding of the proteome.

Our approach is to apply multidisciplinary methods to understand disease mechanisms including proteomics, transcriptomics, computational modeling, cell biology and imaging, and protein biochemistry.
