Comparative Analyses Of Adeno-Associated Viral Vector Serotypes 1, 2 And 9 In The Sod Mouse Model Of Amyotrophic Lateral Sclerosis, Talia Hartman, Jeremy Francis, Paola Leone

6–7-week-old G93A SOD mice were given 1x1010 vector genomes of three different self-complimentary (sc) AAV capsid serotypes (AAV1, 2, and 9) all containing an identical CBh-driven GFP reporter expression cassette. Each serotype was delivered via either the intrathecal (IT) or intra cisterna magna (ICM) route of administration (ROA). Transduction by each serotype, via each of the two ROA was compared for the cortex and each of the lumbar, thoracic, and cervical regions of the spinal cord, with percent neuronal tropism calculated in each region. AAV2 was effective at transducing spinal cord neurons but disappointingly ineffective at transducing cortical neurons by …
Protein Misfolding Toxicity And Inclusion Formation In Cellular Models Of Neurodegeneration, Sonja E. Di Gregorio
Protein Misfolding Toxicity And Inclusion Formation In Cellular Models Of Neurodegeneration, Sonja E. Di Gregorio
Electronic Thesis and Dissertation Repository
Protein misfolding characterizes most neurodegenerative diseases. Protein misfolding is the conversion of specific proteins from their normal, often soluble, and native three-dimensional conformation into an aberrant, often insoluble, non-functional conformation. Protein inclusions and aggregates are among the major pathological hallmarks of protein misfolding associated with many neurodegenerative diseases. Yet, the role of aggregates and inclusions is not clearly defined and heavily debated. This study utilizes powerful genetic approaches in yeast and verification in mammalian neuronal cell lines to address the misfolding and toxicity of three proteins, the Rho Guanine Nucleotide Exchange Factor (RGNEF), Matrin3, which are involved in amyotrophic lateral …

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by motor neuron death and subsequent muscle atrophy. Approximately 15% of ALS cases are inheritable, and mutations in the Fused in Sarcoma (FUS) gene contribute to approximately 5% of these cases, as well as about 2% of sporadic cases. FUS performs a diverse set of cellular functions, including being a major regulator of RNA metabolism. FUS undergoes liquid- liquid phase transition in vitro, allowing for its participation in stress granules and RNA transport granules. Phase transition also contributes to the formation of cytoplasmic inclusions found in the …
