The T Cell Response In A Mouse Model Of Multiple System Atrophy, Nicole Jane Corbin-Stein Sep 2024

The T Cell Response In A Mouse Model Of Multiple System Atrophy, Nicole Jane Corbin-Stein

All ETDs from UAB

Multiple System Atrophy (MSA) is a fatal and rare demyelinating synucleinopathy, characterized by the accumulation of alpha-synuclein (α-syn) in glial cytoplasmic inclusions (GCIs) within oligodendrocytes. This condition is marked by neuroinflammation, demyelination, and neurodegeneration in areas showing GCI pathology, involving antigen presentation by myeloid cells and infiltration of CD4+ and CD8+ T cells. Despite strong evidence of neuroinflammation in post-mortem MSA tissue, the specific mechanisms driving the disease pathogenesis remain elusive. In prior research using the Olig001-SYN mouse model, which involves the modified AAV vector, it was shown that depleting CD4+ T cells can reduce neuroinflammation and demyelination. Notably, this …

Parkinson’s disease is the most common motor neurodegenerative and is characterized by intracellular inclusions of misfolded protein α-synuclein termed Lewy Pathology. At least 80% of PD sufferers also experience non-motor symptoms along with, and sometimes preceding, the motor symptoms. Symptoms such as apathy, hallucinations, anxiety and depression could be caused by α-synuclein inclusions causing dysfunction in the amygdala. Lewy pathology in the amygdala of PD patients is robust and has also been observed in a number of other diseases like Dementia with Lewy Bodies and Alzheimer's disease. In our lab, we have shown that using preformed fibrils to induce α-synuclein …


The Effect Of Progranulin On Lysosomal Function In Bv2 Cells, Michelle Park Sep 2024

The Effect Of Progranulin On Lysosomal Function In Bv2 Cells, Michelle Park

Neurodegenerative diseases afflict nearly 7 million people in United states, constituting a significant portion of the 600 known neurological disorders. Characterized by the gradual loss of neurons and axons within the central nervous system (CNS), these conditions stem from chronic inflammatory activation of the brain. Chronic inflammation disrupts important processes such as autophagy lysosome pathway, a self-degradative process that eliminates protein aggregates and damaged organelles. Trehalose, a non-reducing disaccharide that triggers autophagic flux in neuronal cells and promotes the clearance of protein aggregates; however, without understanding the mechanism behind how trehalose affects these functions, it lacks value. In our study, …
