Summary
Particular immune cell populations (innate T cells), have a critical role in immunity. These cells are stimulated by bacterial cell wall components and are one of the first cells to appear after infection. We have shown that these innate T cells are stimulated by oral bacteria that cause the disease chronic periodontitis. This project will investigate how these innate T cells affect bacterial induced periodontitis and what role they play in disease outcomes.
A Multi-protein Vaccine Targeting The Oral Pathogens Associated With Chronic Periodontitis

Summary
Periodontitis is a chronic inflammatory disease associated with specific bacteria leading to the destruction of the toothÍs supporting tissues and ultimately tooth loss and is a major public health problem in all societies. Our research is focused on designing a vaccine that targets the major bacteria associated with periodontitis. We aim to produce a triple antigen vaccine and investigate the applicability of a vaccine administered under the tongue as an alternative to needle injections.
Evaluation Of Tissue Engineered Decellularised Biphasic Constructs For Periodontal Regeneration

Summary
This project aims to regenerate the tissues lost as a result of gum disease. This will be done using scaffolds that replicate the complex structure of periodontal tissues.The scaffolds will be loaded with cells and allowed to mature before the cellular component is removed. The resultant construct is then inserted back into periodontal defects where it will be repopulated by host cells. This approach has the potential to be developed into an off-the-shelf clinical treatment.
Comparison Of Periodontal Ligament Stem Cells And Induced Pluripotent Periodontal Ligament Stem Cells For Periodontal Regeneration

Summary
In the first part of this study we will determine whether induced pluripotent stem cells or adult stem cells from the periodontal ligament are better candidates for periodontal regeneration. Secondly, using CAD/CAM technology we will make tissue engineering scaffolds tailored to fit periodontal defects and seeded with stem cells to improve on current techniques used to regenerate damaged tissues around teeth affected by periodontal disease.
How Are Periodontal Disease And Rheumatoid Arthritis Inter-related?

Summary
Periodontal (gum) disease and rheumatoid arthritis are two of the most common chronic inflammatory diseases affecting humans. These two diseases have remarkably similar patterns of tissue destruction. It is possible that chronic periodontitis may prime or predispose susceptible individuals to developing rheumatoid arthritis. Treatment of periodontal disease may help reduce the severity of rheumatoid arthritis.
Targeting Histone Deacetylases 1 And 5 To Reduce Inflammation And Bone Loss In Periodontitis.

Summary
Bone loss and tooth loosening are serious complications in periodontitis. Despite the prevalence of this disease current treatments do not directly stop the bone loss. Our recent laboratory studies show inhibiting histone deacetylase (HDAC) activity with very low doses of inhibitors can effectively suppress this bone loss in periodontitis. This project aims to investigate specific targeting inhibitors of HDAC 1 and HDAC 5 to treat periodontitis by enhancing bone formation and reducing bone loss.
