Defective Dynamics Of Mitochondria In Amyotrophic Lateral Sclerosis And Huntington's Disease, Wenjun Song
Defective Dynamics Of Mitochondria In Amyotrophic Lateral Sclerosis And Huntington's Disease, Wenjun Song
Electronic Theses and Dissertations
Mitochondria play important roles in neuronal function and survival, including ATP production, Ca2+ buffering, and apoptosis. Mitochondrial dysfunction is a common event in the pathogenesis of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and Huntington's disease (HD); however, what causes the mitochondrial dysfunction remains unclear. Mitochondrial fission is mediated by dynamin-related protein 1 (DRP1) and fusion by mitofusin 1/2 (MFN1/2) and optic atrophy 1 (OPA1), which are essential for mitochondrial function. Mutations in the mitochondrial fission and fusion machinery lead to neurodegeneration. Thus, whether defective mitochondrial dynamics participates in ALS and HD requires further investigation. ALS is a fatal …
Amelioration Of Amyloid Burden In Advanced Human And Mouse Alzheimer's Disease Brains By Oral Delivery Of Myelin Basic Protein Bioencapsulated In Plant Cells, Neha Kohli
Electronic Theses and Dissertations
One of the pathological hallmarks of Alzheimer's disease (AD) is the amyloid plaque deposition in aging brains by aggregation of amyloid-β (Aβ) peptides. In this study, the effect of chloroplast derived myelin basic protein (MBP) fused with cholera toxin subunit B (CTB) was investigated in advanced diseased stage of human and mouse AD brains. The CTB-fusion protein in chloroplasts facilitates transmucosal delivery in the gut by the natural binding ability of CTB pentameric form with GM1 receptors on the intestinal epithelium. Further, bioencapsulation of the MBP within plant cells confers protection from enzymes and acids in the digestive system. Here, …
