Applications are invited for a fully-funded three year PhD to commence in October 2020.
The PhD will be based in the Faculty of Science and Health, and will be supervised by Dr Sarah Fouch, Professor Darek Gorecki and Dr Kristina Wanyonyi.
The work on this project will involve:
● Working with clinical samples, from varying geographical locations, to contribute and enhance understanding of the bacterial species and expression levels of P2X7 associated with the initial and chronic phases of periodontitis.
● Investigating the bacterial/P2X7 interactions to identify their importance in periodontitis.
● Evaluating potential treatment targets for both the initial and chronic phases of periodontitis.
This project brings together expertise within Microbiology, Dentistry and Biochemistry to contribute and enhance understanding of Periodontitis, a disease affecting 45% of the population (1) that has a significant health impact. Periodontitis causes the destruction of periodontal connective tissue, bone and ultimately tooth loss but also increases the risk of several systemic conditions including cardiovascular disease, diabetes and obesity.
Periodontitis is a pathology cause by a hyperimmune response against bacteria in the oral cavity. Aimed primarily at pathogen elimination, the host defence includes activation of acquired and innate immunity triggered by extracellular ATP (eATP) released from damaged cells acting on the P2X7 ATP receptor (purinoceptor) (2,3). However, P2X7 activation can result in both positive and negative clinical outcomes depending on a range of factors (4).
The current project aims to use molecular, biochemical and classical culture methods to identify and determine P2X7/bacterial interactions to ascertain the role of such interplay in differing stages of periodontal disease and identify whether modulation of P2X7 receptors can alter the disease progression
The Portsmouth Biochemistry and Microbiology laboratories have expertise and specialised equipment and, discipline specific training will be provided. In addition, a full program of graduate training will be provided by the Graduate School.
