Characterization Of Differentiation And Prognostic Biomarkers On Cd8+ Tumor-Infiltrating Lymphocytes In Metastatic Melanoma, Richard C. Wu
UT GSBS Dissertations and Theses (Open Access)
CD8+ cytotoxic T lymphocytes (CTL) frequently infiltrate tumors, yet most melanoma patients fail to undergo tumor regression. We studied the differentiation of the CD8+ tumor-infiltrating lymphocytes (TIL) from 44 metastatic melanoma patients using known T-cell differentiation markers. We also compared CD8+ TIL against the T cells from matched melanoma patients’ peripheral blood. We discovered a novel subset of CD8+ TIL co-expressing early-differentiation markers, CD27, CD28, and a late/senescent CTL differentiation marker, CD57. This CD8+CD57+ TIL expressed a cytolytic enzyme, granzyme B (GB), yet did not express another cytolytic pore-forming molecule, perforin (Perf). In contrast, the CD8+CD57+ T ...

Compound 186 Is A Negative Allosteric Modulator Of Dopamine D2 Receptors: Implications For Improving Schizophrenia Therapy, Jayant Bhandari, Jordan Mah, Ritesh Daya, Rodney L. Johnson, Ram K. Mishra
Excessive dopamine transmission in the striatum via the dopamine D2 receptor (D2R) has been implicated in inducing positive symptoms of schizophrenia (such as hallucinations and delusions). While it is known that antipsychotic drugs alleviate these symptoms by blocking the active site of D2R, other drugs such as allosteric modulators can also decrease dopamine’s ability to bind this receptor, by binding to an allosteric site on D2R. We evaluated the ability of a newly synthesized molecule, compound 186, to modulate the binding of tritiated norpropylapomorphine (NPA)—a high-affinity D2R agonist—in the bovine striatum. Through receptor binding assays, we found ...

The Effects Of Hydrostatic Pressure On Early Endothelial Tubulogenic Processes, Ryan M. Underwood University of Kentucky
The Effects Of Hydrostatic Pressure On Early Endothelial Tubulogenic Processes, Ryan M. Underwood
Theses and Dissertations--Biomedical Engineering
The effects of mechanical forces on endothelial cell function and behavior are well documented, but have not been fully characterized. Specifically, fluid pressure has been shown to elicit physical and chemical responses known to be involved in the initiation and progression of endothelial cell-mediated vascularization. Central to the process of vascularization is the formation of tube-like structures. This process—tubulogenesis—is essential to both the physiological and pathological growth of tissues. Given the known effects of pressure on endothelial cells and its ubiquitous presence in the vasculature, we investigated pressure as a magnitude-dependent parameter for the regulation of endothelial tubulogenic ...

The Role Of Neutrophils In Severe Asthma, Afia Aziz-Ur-Rehman
Open Access Dissertations and Theses
Various studies have shown an association between neutrophilic airway inflammation and severe asthma, but have failed to establish a causal relationship. In these studies airway neutrophilia could be due to high steroid doses, an airway infection, an epiphenomenon of severe asthma or a combination of these. We have examined the role of neutrophils in severe asthma in patients on optimum steroid doses with controlled eosinophilic airway inflammation and chemotactic activity of IL-17 as one potential mechanism of neutrophil recruitment to the airway.
We examined the number, viability and activity of neutrophils in blood and sputum of three groups of asthma ...
