  1. Modeling Alzheimer's Disease Using Cellular Reprogramming Technologies

    Two cellular reprogramming technologies have emerged that demonstrate that cell-fate can be converted by ectopic expression of defined transcription factors: induced pluripotent stem (iPS) cell technology and induced neuronal (iN) cell technology. These recent advances in cell reprogramming …

  2. Topology and geometry-based methods for quantifying the complexity of protein structures

    … enable the topological analysis of physical systems of filaments, such as those formed by proteins. In this dissertation we employ tools from knot theory in combination with available experimental data and molecular simulations to analyze the topological complexity of tau proteins. These …

  3. Be Eaten to Stay Healthy: Elucidating the Mechanisms of Mitochondrial Quality Control by Mitophagy

    … cells, directly linking mitophagy to neurodegeneration. The role of these two proteins in this mitophagy is further explored in the first part of this dissertation. We propose a model whereby a cleavage product of PINK1 in the cytosol binds Parkin and prevents its translocation to …

  4. Role of Gigaxonin in the Regulation of Intermediate Filaments: a Study Using Giant Axonal Neuropathy Patient-Derived Induced Pluripotent Stem Cell-Motor Neurons

    Patients with giant axonal neuropathy (GAN) exhibit loss of motor and sensory function and typically live for less than 30 years. GAN is caused by autosomal recessive mutations leading to low levels of gigaxonin, a ubiquitously-expressed cytoplasmic protein whose cellular roles are poorly …

  5. Investigating neurodegenerative diseases with small molecule modulators

    … complex and interconnected architecture of the nervous system as well as the often pleiotropic nature of these diseases. Cell culture models of neurodegenerative diseases, although seldom recapitulating all aspects of the disease phenotype, enable investigation of specific aspects of these …

  6. Polyglutamine monomer structure and its implications for molecular self-assembly

    Polyglutamine is a naturally occurring peptide found within several proteins in neuronal cells of the brain, and its aggregation has been implicated in several neurodegenerative diseases, including Huntington's disease. The resulting aggregates have been demonstrated to possess ~-sheet structure, …
