Development Of New Treatments For Asthma And Neuropathic Pain Based On Ɣ-Aminobutyric Acid A Receptor (Gabaar) Ligands, Nicolas Mark Zahn
Development Of New Treatments For Asthma And Neuropathic Pain Based On Ɣ-Aminobutyric Acid A Receptor (Gabaar) Ligands, Nicolas Mark Zahn
Theses and Dissertations
The γ-aminobutyric acid A receptor (GABAAR) is a ligand-gated pentameric chloride channel consisting of several identified subunits: α1-6, β1-3, γ1-3, δ, ε, π, θ, ρ1-3.1-2 Typical arrangement of subunits consists of two α subunits, two β subunits, and one γ subunit.3 GABAARs have two binding sites for the endogenous ligand γ-aminobutyric acid (GABA), between the α and β subunits. GABAARs also have a binding site for positive allosteric modulators, such as benzodiazepines, between the α and γ subunits.4-5 Due to their ability to treat anxiety, epilepsy, insomnia, and muscle relaxation, benzodiazepines are widely prescribed pharmaceuticals.6-7 Still, adverse effects result from …
Evaluating The Biological Activities Of Novel Histone Deacetylase Inhibitors (Hdaci) In Adherent And Nonadherent Tumor Cell Lines, Samer Alanani
Evaluating The Biological Activities Of Novel Histone Deacetylase Inhibitors (Hdaci) In Adherent And Nonadherent Tumor Cell Lines, Samer Alanani
Theses and Dissertations
Epigenetic dysregulations are linked to many human diseases including neurodegenerative disorders, immunodeficiencies, cardiac disease, and most notably cancer. Changes in the mechanisms of histone modifications have been recognized as hallmarks of carcinogenesis. One of these modifications is histone acetylation which is regulated by the activities of histone acetyltransferases (HATs) and histone deacetylases (HDACs). The reversible actions of these enzymes govern the acetylome and maintain its balance allowing for activation and repression of gene transcription. However, aberrant overexpression of HDACs in certain tumors is associated with decreased levels of transcription leading to tumor progression and survival. Hence, small-molecule histone deacetylase inhibitors …
Modeling The Bidirectional Glutamine/ Ammonium Conversion Between Cancer Cells And Cancer-Associated Fibroblasts, Peter Hinow, Gabriella Pinter, Wei Yan, Shizhen Emily Wang

Like in an ecosystem, cancer and other cells residing in the tumor microenvironment engage in various modes of interactions to buffer the negative effects of environmental changes. One such change is the consumption of common nutrients (such as glutamine/Gln) and the consequent accumulation of toxic metabolic byproducts (such as ammonium/NH4). Ammonium is a waste product of cellular metabolism whose accumulation causes cell stress. In tumors, it is known that it can be recycled into nutrients by cancer associated fibroblasts (CAFs). Here we present monoculture and coculture growth of cancer cells and CAFs on different substrates: glutamine and ammonium. …

Lymphocyte migration is critical for recognizing pathogenic challenges in a timely manner and generating effective, rapid immune responses. Lymphocyte numbers in secondary lymphoid tissues such as lymph nodes are rapidly and dramatically increased during an immune response. Lymphocytes use specific adhesion molecules and intracellular signaling cascades to migrate and enter secondary lymphoid tissues under resting conditions. It is not clear if the same migration and/or entry pathways are utilized when secondary lymphoid …
Age-Associated B Cell And T Helper Cell Dysfunction In Rhesus Macaques, Evan Knox Stalvig
Age-Associated B Cell And T Helper Cell Dysfunction In Rhesus Macaques, Evan Knox Stalvig
Theses and Dissertations
The immune system undergoes drastic changes as we age, known as immunosenescence. An example of this is the dysfunction and subpopulation distribution changes of immune cells. Due to immunosenescence, the elderly have a higher risk of complications and rapid progression of new challenges to the immune system, including human immunodeficiency virus (HIV). In an effort to determine the mechanism of dysfunction of humoral immunity due to age, I compared B cell and T cell responses to non-specific, mitogenic stimuli between aged and young adult rhesus macaque peripheral blood mononuclear cells (PBMCs). Analysis by flow cytometry revealed several differences in B …
Use Of Photobiomodulation In Osteoclast Formation: Possible Intervention For The Treatment Of Osteoporosis, Lisa Lauren Anderson-Antle
Use Of Photobiomodulation In Osteoclast Formation: Possible Intervention For The Treatment Of Osteoporosis, Lisa Lauren Anderson-Antle
Theses and Dissertations
After critically examining the literature to gain a robust understanding for the pathogenesis of bone loss, specifically osteoporosis, the development of a possible new intervention to prevent or treat osteoporosis was explored. The purpose of this dissertation was to pilot test a new protocol designed to answer the broad research question: Does Near-Infrared Light Emitting Diode (NIR-LED) treatment affect Receptor Activator of Nuclear Factor Kappa-B Ligand (RANKL) induced osteoclastogenesis in a cell culture model?
Osteoporosis is defined as a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased susceptibility to …
Th17 Cell-Associated Response To Borrelia Burgdorferi Outer Surface Protein A, Megan Elizabeth Johnson
Th17 Cell-Associated Response To Borrelia Burgdorferi Outer Surface Protein A, Megan Elizabeth Johnson
Theses and Dissertations
Arthritis is a common symptom of Lyme disease, a debilitating condition resulting from infection with Borrelia burgdorferi. A protein found on the surface of B. burgdorferi, outer surface protein A (OspA), is known to elicit an inflammatory immune response involving T helper cells. T helper 17 (Th17) cells are associated with the inflammatory cytokines interleukin-17 (IL-17) and interleukin-23 (IL-23) and have been implicated in the development of Lyme arthritis. The objective of this thesis is to provide further characterization of the immune response to B. burgdorferi OspA. The central hypothesis of this thesis is: Vaccination with OspA will predispose mice …
Metformin-Induced Pedf Expression Regulates Cell Proliferation And Lipid Metabolism In Prostate Cancer Cells, Miguel Angel Tolentino
Metformin-Induced Pedf Expression Regulates Cell Proliferation And Lipid Metabolism In Prostate Cancer Cells, Miguel Angel Tolentino
Theses and Dissertations
Prostate cancer (PCa) is one of the most common cancers in American males. A high fat diet and obesity accelerate PCa progression and increase the 1risk of death from disease. Epidemiological studies have indicated that PCa patients with type 2 diabetes have higher mortality rates than PCa patients without diabetes. Type 2 diabetics who are on metformin, a drug to control blood sugar levels, show a delay in PCa progression in comparison with PCa patients with type 2 diabetes who are not on metformin. It has been proposed that metformin inhibits proliferation via activation of AMP-activated protein kinase (AMPK) or …
Identification Of Immunomodulatory Cells Induced By 670 Nm Light Therapy In An Animal Model Of Multiple Sclerosis, Erin Christine Koester
Identification Of Immunomodulatory Cells Induced By 670 Nm Light Therapy In An Animal Model Of Multiple Sclerosis, Erin Christine Koester
Theses and Dissertations
Multiple sclerosis is an autoimmune, demyelinating disease characterized by neurodegeneration and inflammation of the central nervous system. It affects approximately 250,000 people in the United States alone, with women being affected two times more than men. Experimental Autoimmune Encephalomyelitis (EAE) is the primary animal model of MS, sharing clinical signs and histopathology with MS. The current paradigm supports MS/EAE induction by myelin reactive CD4+ T cells that cross the blood brain barrier to induce an inflammatory response that leads to the destruction of the myelin sheath and eventual loss of axons. Recent data suggest that axonal loss and disease progression …
