Differential Microglial Activation Following Immune Challenge In Peripubertal And Adult Outbred Mice, David J. Placzek Jul 2015

Differential Microglial Activation Following Immune Challenge In Peripubertal And Adult Outbred Mice, David J. Placzek

Masters Theses

Pubertal development is a time of growth and development in the brain, leading to high sensitivity during this period. Past research in our lab has shown that shipping female inbred and outbred mice during pubertal development alters their sensitivity to steroid hormones in adulthood, thus affecting sexual receptivity, cognition, depression-like behavior, and anxiety-like behavior. Here, we test the hypothesis that mice treated with lipopolysaccharide during pubertal development would have more active microglia, the brain's immune cells, after injection than mice treated with lipopolysaccharide in adulthood. No significant interactions were observed between treatment and age between any brain area measured, suggesting …


The Effects Of Adolescent Binge Drinking On Corticotropin-Releasing Factor Cells In The Amygdala And Social Predictors Of Alcohol Intake In Male And Female Rats, Chrisanthi Karanikas Jan 2012

The Effects Of Adolescent Binge Drinking On Corticotropin-Releasing Factor Cells In The Amygdala And Social Predictors Of Alcohol Intake In Male And Female Rats, Chrisanthi Karanikas

Masters Theses 1911 - February 2014

Alcohol is one of the most common drugs of choice among adolescents. Normally, the method of consumption is drinking large quantities of alcohol in short periods of time, otherwise known as “binge drinking.” Corticotropin releasing factor (CRF) stress peptide producing cells in central nucleus of the amygdala (CeA) has been implicated in behavioral responses to stress and addiction. The goals of this thesis were to determine the effects of voluntary binge drinking in adolescence and vapor-induced alcohol dependence in adulthood on CRF cells in the CeA. These studies were done using an operant model of voluntary binge drinking in rodents …
