Abstract

Dysferlin deficient muscular dystrophy is a devastating disease that leads to loss of mobility and quality of life in patients. Dysferlin is a 230 kD protein primarily expressed in skeletal muscle that functions in membrane resealing. Dysferlin loss of function leads to a decrease in the membrane resealing response after injury in skeletal muscle, which is thought to cause degeneration of the musculature over time. Dysferlin cDNA is 7.4 kb and exceeds AAV packaging capacity of ~ 5kb. This thesis focuses on the generation of mini dysferlin mutants that can be packaged in AAV for downstream testing of therapeutic efficacy. In addition, this thesis creates the groundwork for preclinical studies in mice that can potentially be translated to human patients. A mouse model for dysferlin deficiency was characterized and key disease phenotypes were identified. In addition, cell lines carrying a genetically encoded calcium indicator protein, gCaMP, were established to measure mini dysferlin resealing capacity and for downstream testing in vivo.
