Alternative Theses and Dissertations (AETDs)

Neuroblastoma (NB) is a highly aggressive, heterogeneous disease that arises from the sympathetic nervous system (SNS) and originates from neural crest cells (NCCs) (1). NB is the most common extracranial cancer in pediatric accounts for 15% of pediatric cancer deaths (2). This high mortality rate is the result of the metastatic, immune evasive, and treatment resistant characteristics of the disease (3). It has been proposed that NB arises from blocks in differentiation during development, resulting in a mixture of two distinct cell types within the tumor: mesenchymal and adrenergic (Figure 1.1) (4,5). The adrenergic cell type is more differentiated, and …

Development Of A Novel Drug Delivery Platform To Treat Hiv-Associated Neurocognitive Disorder, Lina Zhou

Alternative Theses and Dissertations (AETDs)

Despite the significant reduction in HIV prevalence and improvement in life expectancy achieved through the availability of widespread antiretroviral therapy (ART), there remains no definitive cure for HIV. Further, HIV infects the brain as early as eight days after initial peripheral infection leading to neuroHIV and subsequently neuronal damage and cognitive impairment. HIV can enter the brain through several mechanisms, including the migration of infected immune cells (Trojan Horse Mechanism), direct infection of endothelial cells, and cytokine-mediated disruption of the blood-brain barrier (BBB). Consequently, HIV-associated neurocognitive disorder (HAND) remains a significant challenge in the ART era, with an estimated prevalence …

Ftsk Regulates The Assembly Of The Division Machinery In The Ftsz-Less Chlamydia Trachomatis, Mckenna Katherine Harpring Jan 2024

Ftsk Regulates The Assembly Of The Division Machinery In The Ftsz-Less Chlamydia Trachomatis, Mckenna Katherine Harpring

Theses and Dissertations (ETD)

In evolving to obligate intracellular dependence, Chlamydia trachomatis serovar L2 (Ct), has eliminated several gene products essential for cell division in most other bacteria, including FtsZ, the central coordinator of divisome assembly. In the absence of FtsZ, we show that divisome assembly in Ct is initiated by FtsK, a chromosomal translocase. Chlamydial FtsK forms discrete foci at the septum and at the base of the progenitor mother cell, and our data indicate that FtsK foci at the base of the mother cell mark the location of nascent divisome complexes that form at the site where a daughter cell will emerge …


Interplay Of Antibody Responses To Closely Related Viruses And Autoimmunity, Chun-Yang Lin Jan 2024

Interplay Of Antibody Responses To Closely Related Viruses And Autoimmunity, Chun-Yang Lin

Theses and Dissertations (ETD)

Antibodies produced by B cells are crucial for eliminating infectious pathogens and preventing secondary infection. However, antibodies may also bind to self-antigens and contribute to autoimmune disease. While pathogen infections have been associated with development of autoimmune diseases, the precise contributions of viral infections to autoimmunity remain elusive. The presence of autoreactive antibodies is associated with an increased risk of developing autoimmune disease. Thus, analyzing the impact of viral infection and vaccination on the development of autoreactive antibodies will provide essential insight into mechanisms that contribute to autoimmune disease.
