The Mglur2/3 Agonist Ly397268 Improves Morphometric And Behavioral Outcomes In R6/2 Huntington's Disease Mice, Dennis Craig Lafferty Dec 2010

The Mglur2/3 Agonist Ly397268 Improves Morphometric And Behavioral Outcomes In R6/2 Huntington's Disease Mice, Dennis Craig Lafferty

Theses and Dissertations (ETD)

A prominent theory for the pathology of Huntington's Disease (HD) is the excitotoxic injury to the striatum. Continual exposure of ionotropic NMDA receptors to glutamate from the cortex can be excitotoxic in HD and leave striatal neurons vulnerable to damage. Activation of presynaptic mGluR2/3 by an agonist dampens glutamate release from corticostriatal terminals. Treatments that target excitoxicity and oxidative stress thus may improve some of the symptoms in HD patients and it is therefore logical to pursue therapies aimed in this direction. LY379268 is an inviting mGluR2/3 agonist that has been shown to be neuroprotective in hypoxic and ischemic injuries …


Tetrahydroisoquinoline Neurotoxins In Parkinson Disease, Michael G. Decuypere May 2010

Tetrahydroisoquinoline Neurotoxins In Parkinson Disease, Michael G. Decuypere

Theses and Dissertations (ETD)

The goal of this dissertation work was to (1) determine the distribution of several tetrahydroisoquinoline (TIQ) derivatives in rodent, normal human and Parkinson disease (PD) brain, (2) quantify the levels of these TIQ derivatives in common food sources in an effort to link specific food intake patterns with the development of PD and (3) examine the neurotoxicity of select TIQ derivatives in human dopaminergic cell culture. The TIQs are a family of monoamine alkaloids that share structural homology with 1-methyl-4-phenyl-1,2,3,6-tetrahyrdropyridine (MPTP), can be formed from dopamine or its oxidized metabolites and may be involved in the pathogenesis of monoaminergic cell …
