Unraveling The Consequence Of Adult Onset Sulfatide Depletion: Its Implications In Myelin And Axonal Heath In The Context Of Neurodegenerative Disease, Elizabeth Dustin

Theses and Dissertations

Multiple Sclerosis is an immune mediated disease of the CNS. MS is diagnosed through detection of demyelinated regions. However, recent studies demonstrate that Normal Appearing White Matter (NAWM) contains substantial pathology. One such pathology observed in the NAWM is the reduction of sulfatide. The proper stoichiometry of lipids in myelin acts to maintain rapid conduction velocity, provide trophic support to the neuron, and protect the axon from degeneration. We previously characterized a mouse lacking sulfatide’s synthesizing enzyme, CST through constitutive gene disruption and demonstrate that sulfide is required for proper stability of the myelin sheath. However, since MS is typically …
