Peptoanaerobacter Stomatis Interactions With Neutrophils., Emeri Jimenez Flores
Electronic Theses and Dissertations
Peptoanaerobacter stomatis is a newly appreciated taxon, present in high numbers in oral biofilms from periodontal patients. However, little is known about this organism’s potential virulence and its interaction with the host immune response. Therefore, to better understand the role of P. stomatis in periodontitis, we studied its interactions with neutrophils. Human neutrophils were challenged with P. stomatis strain CM2 or S. aureus AF488 (positive control) for 30 min. Bacterial internalization was examined by ImageStreamX imaging flow cytometry. Bacterial viability was assessed by colony-forming unit assays and Baclight assays. Phagocytosis-stimulated respiratory burst response was measured by flow cytometry. The fusion …

Abin1 In The Pathogenesis Of Glomerulonephritis And The Novel Polocyte-Neutrophil Proinflammatory Axis., Erik Anderson Korte
Electronic Theses and Dissertations
Glomerulonephritis (GN) is the most common cause of end-stage renal disease worldwide and is characterized by deposition of immune complex, inflammation, proteinuria and podocyte damage. Immunosuppressive therapy is effective in less than 50% of patients, indicating that immunological activity is not the only relevant cause of kidney injury. While methods have been described for neutrophil-mediated immune activation, specific glomerular mechanisms for recruitment of neutrophils and development of GN have not been determined. Here I present a pathogenic mechanism for the development of GN involving a novel podocyte-neutrophil axis and reveal the importance of glomerular NF-κB inhibition by the ubiquitin binding …
