Selenomonas Sputigena: Growth Conditions And Projected Virulence Factors Of An Emerging Oral Pathogen, Kayla A. Keller
Selenomonas Sputigena: Growth Conditions And Projected Virulence Factors Of An Emerging Oral Pathogen, Kayla A. Keller
Theses and Dissertations
Periodontal diseases are ubiquitous diseases. They can affect people through a chronic infection that happens over a lifetime, but also as an aggressive infection that afflicts the younger population. It not only results in tooth loss and a lower quality of life, but it can also lead to fatal secondary infections like cervical cancer, heart disease, and Alzheimer’s disease. This study looks at Selenomonas sputigena, an emerging oral pathogen, that has been hypothesized to contribute to periodontal disease. It has been linked to fatal septicemia and has been found in increased abundance within the oral biofilm during peak infection. …
Bromodomain And Extraterminal Domain (Bet) Inhibitor Rvx-208 Ameliorates Periodontal Bone Loss, Nicholas J. Clayton
Bromodomain And Extraterminal Domain (Bet) Inhibitor Rvx-208 Ameliorates Periodontal Bone Loss, Nicholas J. Clayton
Theses and Dissertations
Periodontal disease affects 47% of Americans over 30 and is a growing global concern. Current treatments for periodontal disease focus on the mechanical elimination of periodontal biofilms. Very few treatments are available that target the rampant, unregulated host immune response that is ultimately responsible for tissue degradation. BET proteins have been shown to play critical roles in inflammatory gene regulation and are therefore potentially ideal therapeutic targets for treating periodontal disease. RVX-208 is a selective BET-inhibitor with a high affinity for Bromodomain 2 (BD2) as compared to BD1 in BET proteins. Our previous studies have shown that RVX-208 inhibits inflammatory …
The Role Of Human Msc Derived Exosomes In The Treatment Of Periodontal Diseases, Sonia S. Talegaonkar
The Role Of Human Msc Derived Exosomes In The Treatment Of Periodontal Diseases, Sonia S. Talegaonkar
Theses and Dissertations
Periodontal disease affects 47% of Americans over 30. Characterized by microbial dysbiosis and unregulated inflammation, severe periodontitis causes degradation of bone and soft tissue around teeth. Current treatments have limited regenerative outcomes and frequent reinfection by harmful bacteria. Human mesenchymal stem cells (hMSCs) have been shown to promote wound healing and tissue regeneration. Many therapeutic benefits of hMSCs are due to their secretome products, like exosomes. Our long-term goal is to develop periodontal therapies with hMSC exosomes. The objectives of this study were to determine the effect of hMSC-derived exosomes on cellular activity of hMSCs and investigate whether hMSC exosome …
Characterization Of Putative Porphyromonas Gingivalis Rna-Binding Proteins, Holly Dwyer
Characterization Of Putative Porphyromonas Gingivalis Rna-Binding Proteins, Holly Dwyer
Theses and Dissertations
Porphyromonas gingivalis (P. gingivalis) is a gram-negative, anaerobic bacterium recognized as a major player in progression of periodontal disease. P. gingivalis survives in the oral cavity while being exposed to dynamic environmental conditions such as pH, temperature, nutrient availability and host immune responses such as oxygen tension and nitrosative stress. Survival and pathogenesis of P. gingivalis in the oral cavity require mechanisms to regulate gene expression in response to the extracellular signals. Little is known about the regulatory mechanisms of P. gingivalis in the oral cavity, so it is important to investigate and characterize these regulatory mechanisms. Adaptation to environmental …
Analysis Of Plasminogen Binding To Treponema Denticola, A Key Periopathogen, Brittney Tegels
Analysis Of Plasminogen Binding To Treponema Denticola, A Key Periopathogen, Brittney Tegels
Theses and Dissertations
Periodontitis is a chronic inflammatory disease that affects over 116 million adults in the United States. A shift in the normal microflora occurs as periodontal disease develops resulting in a larger number of Gram-negative anaerobes and spirochetes. An increase in the oral spirochete, Treponema denticola, is highly correlated with periodontal disease progression and severity. The ability of this periopathogen to thrive in the subgingival crevice is dependent on complement evasion mechanisms. Earlier analyses demonstrated that the primary mechanism of T. denticola serum resistance is binding of the human complement regulatory protein, Factor H (FH), to the factor H-binding protein (FhbB). …
