From Pathology To Circuits: Loss Of Pink1 Function In Parkinson’S Disease, Rose Berthe Creed Jan 2020

From Pathology To Circuits: Loss Of Pink1 Function In Parkinson’S Disease, Rose Berthe Creed

Parkinson’s disease (PD) is the most common neurogenerative motor disorder, affecting over 10 million people worldwide. Clinically, PD is diagnosed by presentation of hypokinetic movements such as bradykinesia, rigidity, and resting tremor. Additionally, PD patients have non-motor symptoms that include anosmia, constipation, and hypophonia. Current therapeutics have been successful in treating many of the locomotor symptoms, however no therapies stop or slow disease progression and the effectiveness of current medications diminishes as the symptoms invariably become more severe over the course of many years. Histopathologically, PD diagnosis is confirmed postmortem by two pathological hallmarks: 1. loss of dopaminergic neurons in …


Pharmacodynamic Responses And Efficacies Associated With Lrrk2 Inhibition, Kaela Kelly Jan 2020

Pharmacodynamic Responses And Efficacies Associated With Lrrk2 Inhibition, Kaela Kelly

Parkinson’s disease (PD) is an age-related, progressive, movement disorder pathologically characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc) and the presence of proteinaceous aggregates, termed Lewy bodies, that are largely comprised of αSynuclein (αSyn). Missense mutations in the leucine-rich repeat kinase (LRRK2) gene are the most common genetic cause of PD and lead to gain-of-function increases in kinase activity. The G2019S-LRRK2 mutation is the most frequent mutation and elevates kinase activity by ~2-3 fold. Genetic and biochemical evidence suggest elevated LRRK2 kinase activity plays a pathogenic role in the development of PD, implicating LRRK2 …


Role Of Endogenous Tau In Lewy-Like Pathology, Lindsay Stoyka Jan 2020

Role Of Endogenous Tau In Lewy-Like Pathology, Lindsay Stoyka

All ETDs from UAB

Lewy Body Diseases (LBDs) are a group of disorders characterized by intracellular inclusions of misfolded alpha-synuclein (α-synuclein). Of these, Parkinson’s Disease (PD) is the most common neurodegenerative movement disorder, and Dementia with Lewy Bodies (DLB) is the second most common neurodegenerative dementia. PD is characterized clinically by bradykinesia, resting tremor, rigidity, and postural instability. In addition, up to 80% of patients eventually develop dementia, termed Parkinson’s Disease Dementia (PDD). DLB is characterized by onset of dementia before or concurrently with parkinsonism. Currently, no disease-modifying therapies exist for either of these diseases. Lewy pathology is found in regions important for cognition …
