Characterization Of Palmitic Acid Induced Lipotoxicity In Schwann Cells, Amelia Padilla
Characterization Of Palmitic Acid Induced Lipotoxicity In Schwann Cells, Amelia Padilla
Loma Linda University Electronic Theses, Dissertations & Projects
Lipotoxicity is a response to lipid overload that has been associated with cellular dysfunction leading to cellular death. The mechanism of lipotoxicity and its impact on the nervous system is critical as it can lead to debilitating neurological conditions. This study examines key cellular events induced by palmitic acid lipotoxicity (PA-LTx) in Schwann cells cultured in euglycemic and hyperglycemic conditions. The data show that immortalized Schwann cell (iSC), as well as primary Schwann cell (pSC) cultures exposed to elevated levels of PA induced an apoptotic cell death that is dose and time-dependent. The earliest indication of cellular dysfunction was a …
Nanomaterials And Block Copolymers For Overcoming Multidrug Resistance In Cancer, Wesley Livingstone
Nanomaterials And Block Copolymers For Overcoming Multidrug Resistance In Cancer, Wesley Livingstone
Loma Linda University Electronic Theses, Dissertations & Projects
The development of multidrug resistance in cancer is one of the leading causes for decreased chemotherapy efficacy and is particularly threatening to aggressive cancers such as that of the pancreas. In cancers where chemotherapy is amongst the few treatment options, it is crucial to develop chemotherapeutics that either bypass or control the development of multidrug resistance. Polymeric nanomaterials such as Pluronics® are of current interest due to their ability to perform these functions in addition to enhancing pro-apoptotic mechanisms. Using the respectively known chemosensitive and chemoresistant pancreatic adenocarcinoma cell lines MiaPaCa-2 and PANC-1, an in vitro analysis of the synergistic …

Type 1 diabetes mellitus is a chronic inflammatory disease in which the insulin and glutamic acid decarboxylase producing β-cells of the pancreatic islets are killed by autoreactive cells of the immune system in response to a loss of tolerance. Early experiments showed that self-tolerance could be partially restored by oral inoculation with small amounts of insulin. Later experiments showed that insulin autoantigen induced immune tolerance could be greatly enhanced by linkage of β-cell autoantigens (Auto Ag) to adjuvant molecules such as the non-toxic cholera enterotoxin B subunit (CTB). To identify mechanisms responsible for CTB-autoantigen fusion protein suppression of diabetes autoimmunity, …

Dynamic Contrast-Enhanced Mri Of Pancreatic Islet Transplants, Nathaniel K. Chan
Loma Linda University Electronic Theses, Dissertations & Projects
Since its discovery in 1922, insulin has been the life-saving treatment for type 1 diabetes mellitus. As the disease is caused by the loss of insulin-producing pancreatic islets, transplantation of donor islets has the potential to not only supplement insulin replacement therapy but to cure type 1 diabetes. However, long-term insulin independence (> 2 years post-transplant) remains a challenge partly due to low islet blood flow immediately following transplantation leading to hypoxic stress on islets. The goal of our studies is to improve islet engraftment by monitoring and promoting the regrowth and maturation of new islet blood vessels in a …
