Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino
MSU Graduate Theses
Recent insights into the pathological role of Nucleotide P2Y2 receptor suggest P2Y2R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y2R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y2R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y2 in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological …
A Mechanistic And Genomic Analysis Of Molluscum Contagiosum Virus Immune Evasion, Ian Benjamin Harvey
A Mechanistic And Genomic Analysis Of Molluscum Contagiosum Virus Immune Evasion, Ian Benjamin Harvey
Arts & Sciences Electronic Theses and Dissertations
Molluscum contagiosum virus (MCV) is a common human-specific poxvirus with a proclivity for
infecting children and the immune-compromised. A characteristic MCV infection is restricted to
the epidermal layers of the skin and can persist for weeks to years in an otherwise healthy
individual. The high clinical burden of MCV is at odds with our limited knowledge regarding how
it successfully evades the human immune response, which is in part due to the lack of an animal
model or cell line to propagate the virus. Through this dissertation, we have uncovered and
characterized a novel mechanism by which MC80, a protein …
The Enzymatic Function Of The Tir Domain: From Axon Degeneration To Innate Immunity, Kow Essuman
The Enzymatic Function Of The Tir Domain: From Axon Degeneration To Innate Immunity, Kow Essuman
Arts & Sciences Electronic Theses and Dissertations
The Toll/Interleukin-1 Receptor (TIR) domain is an evolutionarily ancient protein domain conserved from bacteria to eukaryotes, and is an essential signaling component of innate immunity pathways. In animal innate immunity, TIR domains have primarily been described for their scaffolding function in assembling protein complexes in host defense. In plant immunity, TIR domains are key components of the intracellular Nucleotide Binding Leucine rich repeat (NLR) immune receptors that confer resistance to pathogens. These NLR receptors trigger cell death and an immune response upon activation, but their mechanism has remained elusive. In bacteria, TIR domain proteins have been suggested to function as …
Molecular And Functional Characterization Of Α-Galactosyl Epitopes In Trypanosoma Cruzi, Uriel Ortega Rodriguez
Molecular And Functional Characterization Of Α-Galactosyl Epitopes In Trypanosoma Cruzi, Uriel Ortega Rodriguez
Open Access Theses & Dissertations
Trypanosoma cruzi, the causative agent of Chagas disease (CD) currently affects 6-7 million people across the world. Currently, only two drugs, benznidazole and nifurtimox, are available for treatment of CD and they are highly toxic and less effective in the chronic stage of the disease. Specific biomarkers for diagnosis and follow-up of treatment do not exist in the clinical settings. following chemotherapy, patients take approximately 10-20 years to exhibit negative seroconversion with the conventional serology assays. Moreover, there is no vaccine available to prevent or treat CD. T. cruzi contains a complex cell surface consisting of several classes of glycoconjugates …
Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay
Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay
Loma Linda University Electronic Theses, Dissertations & Projects
Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It …

Biochemical And Molecular Characterization Of The Prostate-Specific Membrane Antigen (Psma), John Karl Troyer
Theses and Dissertations in Biomedical Sciences
Prostate cancer is the most common malignancy and the second leading cause of cancer death in males in the United States. Additionally, the number of deaths attributed to prostate cancer is increasing at a rate of approximately 8% a year. Development of new diagnostic and therapy strategies are needed in order to improve the life expectancy of patients with this disease. One tool which may allow for improvements in prostate cancer diagnosis and therapy is the monoclonal antibody (MAb) 7E11-C5.3 which was first described in 1987. Since then, the antigen recognized by MAb 7E11-C5.3 has been named the prostate specific …
Maternal Immunomodulation Of Neonatal Alloantigen Response, Leh Chang
Maternal Immunomodulation Of Neonatal Alloantigen Response, Leh Chang
Loma Linda University Electronic Theses, Dissertations & Projects
Remarkable success has been achieved in the transplantation of allogeneic cardiac grafts into newborn infants at Loma Linda University Medical Center. The superior graft survival rate documented in these patients has not correlated with the degree of immunosuppression rendered, or the selection of genetically matched donors. However, the clinical success has correlated with the age of the recipient at the time of receiving a transplant. Patients receiving an allograft within the first few weeks of life are unique in that they seem to accept the alloantigens of their cardiac graft while responding aggressively to antigens in their environment. These observations …
A Batch Method For The Isolation Of Immunogenically Pure Igg, Iga, And Igm From Human Sera, Samuel Christopher Powell
A Batch Method For The Isolation Of Immunogenically Pure Igg, Iga, And Igm From Human Sera, Samuel Christopher Powell
Chemistry & Biochemistry Theses & Dissertations
A method is described for preparing an enriched fraction of the three major antibodies, immunoglobulins IgG, IgA and IgM, from normal human serum by a batch method. Selective precipitation of these proteins was carried out in successive steps using polyethylene glycol (PEG) of average molecular weight 6,000 at concentrations of 7%, 12% and 14% (16) . Zinc sulfate (10 mM) was used to remove highly immunogenic alpha2 macroglobulin from the IgM fraction. IgA, IgM and IgG were further purified by adsorption methods using DEAE-cellulose. Quantitation and qualitation of the enriched fractions showed nearly complete separation of each of the …
