Glyphosate And Dopaminergic Neurotoxicity: Herbicide Impacts On Parkinson's Disease Development, Lojy Hozyen Jan 2023

Glyphosate And Dopaminergic Neurotoxicity: Herbicide Impacts On Parkinson's Disease Development, Lojy Hozyen

Undergraduate Research Posters

Nearly one million individuals in the United States are living with Parkinson’s disease (PD). In the past two decades, the death rate from PD has risen by about 63 percent in the United States. Major findings have been made in the past five years about the potential impact of glyphosate (N-(phosphonomethyl) glycine) exposure on the onset of PD symptoms. The purpose of this meta-analysis is to provide a compiled update on the chemical and biological alterations that glyphosate imposes on the human brain. A meta-analysis was conducted to create a quantitative estimate of the connection between PD and glyphosate. Findings …

Muscarinic Excitation Of Dopamine Neurons In The Ventral Tegmental Area Via Activation Of A Trpc-Like Cation Conductance, Yu Tzu Chen Jan 2021

Muscarinic Excitation Of Dopamine Neurons In The Ventral Tegmental Area Via Activation Of A Trpc-Like Cation Conductance, Yu Tzu Chen

Theses and Dissertations

Dopaminergic (DA) neurons in the ventral tegmental area (VTA) play a crucial role in reward and motivational behaviors, including the development of drug addictions. VTA DA neurons receive excitatory cholinergic inputs from the mesopontine tegmentum. Blockage of the M5 muscarinic receptor in DA neurons has been shown to attenuate drug-induced DA release and abuse-related behaviors, but the molecular mechanism is unknown. In this study, experiments were designed to identify the electrophysiological effects of muscarinic agonism in the modulation of action potential kinetics and firing patterns in VTA DA neurons of mice. Pharmacology of the muscarinic receptor-evoked current was also characterized. …
