Discovery Of Natural Product Analogs Against Ethanol-Induced Cytotoxicity In Hippocampal Slice Cultures, Meredith A. Saunders-Mattingly Jan 2018

Discovery Of Natural Product Analogs Against Ethanol-Induced Cytotoxicity In Hippocampal Slice Cultures, Meredith A. Saunders-Mattingly

Theses and Dissertations--Psychology

An estimated 13.9% of Americans currently meet criteria for an alcohol (ethanol; EtOH) use disorder (AUD). While there are 4 medications approved by the Food and Drug Administration (FDA) to treat AUD, these treatments have demonstrated poor clinical efficacy. Our ongoing research program encompasses a multi-tiered screening of a natural product library and validation process to provide novel information about the mechanisms underlying EtOH-induced changes in neurobiology and to identify novel chemical scaffolds to be exploited in the development of pharmacological treatments for AUD in a rodent organotypic hippocampal slice culture model. Initial screens of several natural product compounds identified …


Novel Spoxazomicins Derived From Streptomyces Sp. Rm-14−6 Attenuate Ethanol Induced Cytotoxicity In Vitro, Meredith A. Saunders Jan 2016

Novel Spoxazomicins Derived From Streptomyces Sp. Rm-14−6 Attenuate Ethanol Induced Cytotoxicity In Vitro, Meredith A. Saunders

Theses and Dissertations--Psychology

An estimated 13.9% of Americans currently meet criteria for an alcohol use disorder. Ultimately, chronic alcohol use may result in neurological deficits, with up to 85% of alcoholics exhibiting signs of cognitive decline. However, biochemical and behavioral factors contributing to this decline have remained elusive. Our ongoing research program encompasses a multi-tiered screening of a natural product library and validation process to provide novel information about mechanisms underlying these deficits and to identify novel chemical scaffolds to be exploited in the development of pharmacological treatments for alcohol use disorders in a rodent organotypic hippocampal slice culture mode. Experiment 1 sought …


Microglia Activation In A Rodent Model Of An Alcohol Use Disorder: The Importance Of Phenotype, Initiation, And Duration Of Activation, Simon A. Marshall Jan 2013

Microglia Activation In A Rodent Model Of An Alcohol Use Disorder: The Importance Of Phenotype, Initiation, And Duration Of Activation, Simon A. Marshall

Theses and Dissertations--Pharmacy

Chronic ethanol exposure results in neuroadaptations that drive the progression of an alcohol use disorder (AUD). One such driving force is alcohol-induced neurodegeneration. Neuroinflammation has been proposed as a mechanism underlying this damage. Although neuroinflammation is a physiological response to damage, overactivation of its pathways can lead to neurodegeneration. A hallmark indicator of neuroinflammation is microglial activation, but microglial activation is a heterogeneous continuum of phenotypes that can promote or inhibit neuroinflammation. Furthermore acute microglial activation is necessary to restore homeostasis, but prolonged activation can exacerbate damage. The diversity of microglia makes both the level and timecourse of activation vital …
