The Role Of Complement C3 In Iga Nephropathy, Sarah Elizabeth Coffee
The Role Of Complement C3 In Iga Nephropathy, Sarah Elizabeth Coffee

IgA nephropathy is an autoimmune disease characterized by glomerular IgA1- containing immunodeposits. These immunodeposits are enriched for aberrantly glycosylated IgA1 bound by IgG autoantibodies and contain complement component C3. Current research suggests a multi-hit disease pathogenesis: IgAN patients have elevated serum levels of IgA1 missing galactose in some hinge region O-glycans; this galactosedeficient IgA1 is recognized by IgG autoantibodies resulting in formation of circulating immune complexes; some of these complexes deposit in the glomeruli and induce kidney injury. As there is no disease-specific treatment, many patients progress to kidney failure. In this master’s thesis I sought to assess whether C3 …

The differentiation of mesenchymal stem cells to pre-osteoblasts, lies upon various transcription factors and physiological signaling, but is also governed by the micro-RNA-23a cluster. The miR-23a cluster has miR-23a, miR-27a and miR-24-2 transcribed from a single promoter as a sole RNA primary transcript. Its effects have been observed in embryonic stem cells, mesenchymal stem cells (MSCs), and in cancer (1-2). It regulates the lineage commitment of MSCs. (3). With respect to bone formation, miR-23a cluster is involved MSCs commitment to and osteoblast maturation (4). Here, through in vivo and in vitro experiments, we report that knock down of microRNA-23a cluster …

Idiopathic pulmonary fibrosis (IPF) is an age-related chronic disease with a me-dian survival period of 3-4 years [1]. Although FDA has approved two drugs that may slow the disease process, there is no effective treatment [2]. IPF is characterized by the excessive deposition of collagen, which leads to deformation of alveolar structure, loss of lung function, and ultimately death [3]. Anti-fibrotic genes such as cyclooxygenase-2 (COX-2) and Heme Oxygenase 1 (HMOX-1) are usually suppressed in the pathogenesis of IPF [4-6], while the mechanisms responsible for the repression of anti-fibrotic genes in IPF are incompletely understood. More evidence has shown that …

HIV-associated neurocognitive disorders (HAND) produces serious neurological dysfunction for > 50% of people living with HIV (PLWH). As antiretroviral therapy (ART) has transformed HIV into a chronic disease, and since most ART does not effectively cross the blood brain barrier, HAND is predicted to further increase in prevalence in PLWH. The HIV-Trans-Activator of Transcription (Tat) is known to persist in the central nervous system (CNS) of chronically infected HIV+ individuals. In several preclinical studies, HIV-Tat has been shown to be neurotoxic and important for HIV pathogenesis. Translocator protein (TSPO), an 18 kDa mitochondrial protein, has been shown to be increased via …
A Gastrointestinal-Specific Antibiotic As An Experimental Treatment For Anxio-Depressive Disorders, Yuang-Tai Huang

Chronic stress is a predisposing factor for various disease states, including neuropsychiatric disorders, such as depression and anxiety [1]. Stress-related disorders have complicated multifactorial etiologies [2]. Advances in psychotherapeutic and psychotropic treatments have occurred, but anxiety and depressive disorders are still prevalent and remain a burden to our societies [3]. More than 30% of major depressive disorder patients fail to remission despite an FDAapproved medication [4]. Meanwhile, the contribution of microbiota-gut-brain axis signaling in both etiologies and treatment of stress-related disorders is increasingly being recognized [5]. More evidence has shown that the gut microbiota has the potential to alter the …
