Conduction States Of The Human Dopamine Transporter, Krasnodara Cameron
Theses and Dissertations
Dysregulation of dopaminergic homeostasis has been established as the primary source of numerous neurological disorders including Parkinson’s and drug addiction. A tonic increase of dopamine (DA) in the nucleus accumbens is required for associating everyday events and behaviors with rewards. Yet many addictive exogenous compounds such as amphetamine (AMPH) and cocaine (COC) produce a much greater augmentation of synaptic DA levels that are linked to euphoria and a shift in behavior towards drug seeking. The protein responsible for maintaining extracellular levels of DA is the dopamine transporter (DAT). It is primarily located in the perisynaptic area at terminals of pre-synaptic …

G protein-coupled receptors (GPCRs) are seven-transmembrane domain receptors that sense extracellular signal and activate intracellular signaling pathways. The serotonin 5HT2A receptor (or 2AR) is one of the GPCRs coupled to Gq proteins, activating PLC and hydrolyzing PIP2. This hydrolysis causes a diffusion of bound PIP2 away from the channel binding site resulting in G protein-gated inwardly rectifying K+ channel (GIRK) inhibition and a downstream stimulation of Ca2+ release from endoplasmic reticulum stores. Previous experiments have demonstrated that the serotonin 5HTA receptor is a target of serotonergic psychedelic drugs, such as LSD, and partially mediates the action of many …
Inhibition Of Mtor Signaling Protects Against Myocardial Reperfusion Injury, Acute Myocardial Infarction, Scott M. Filippone
Inhibition Of Mtor Signaling Protects Against Myocardial Reperfusion Injury, Acute Myocardial Infarction, Scott M. Filippone
Theses and Dissertations
Acute myocardial infarction (AMI) is the leading cause of death worldwide. Currently, the best method of treating cardiac ischemia is early reperfusion which, itself, induces myocardial damage. The mTOR complex is a key regulator of cardioprotection against cell stressors. We hypothesized that reperfusion therapy with Rapamycin, a potent mTOR inhibitor, would reduce infarct size in adult mouse hearts. Rapamycin was administered at the onset of reperfusion following 30 min in situ LAD ligation. After 24 hours of reperfusion, myocardial infarct size and apoptosis were significantly reduced in rapamycin-treated mice compared to control. Rapamycin inhibited pro-apoptotic protein Bax and phosphorylation of …
