Role of bacteria-purinoceptor interactions in pathological changes leading to implant failure

This project is currently not accepting new applicants. View all of our current research projects.

The PhD will be based in the Faculty of Science and Health, and will be supervised by Professor Darek Gorecki and Professor Chris Louca. 

This PhD studentship is one of six PhD studentships funded by the University of Portsmouth in the area of biomaterials and bioengineering. These studentships will support the University’s strategic plan engaging with clinicians working in Portsmouth Hospital Trust to solve real-life medical problems. The successful applicants would be part of a cross-faculty research cluster in medical technologies.

This programme of research involves several Schools based in the Faculty of Science and Health and the Faculty of Technology. The vision of the cluster is to train a cohort of PhD students who contribute to the academic environment, some of whom would be expected to develop academic careers in this expanding area whilst others would be employed in the growing international medical technologies industry. Training would be enhanced by extended visits to other institutions involved in similar research and by visits to hospitals to meet with clinicians involved in the research projects

The scholarship covers tuition fees and an annual maintenance grant of £15,009 (UKRI 2019/20 rate) for three years. Scholarship recipients will also receive up to £3,000 for research project costs/consumables during the duration of the programme.

This is an interdisciplinary proposal between the School of Pharmacy and Biomedical Science, the Dental Academy and Faculty of Technology aimed at understanding the pathological mechanism behind the dental implant failure.

A proportion of dental implants fails due to infection that causes a chronic inflammatory process in the tissue surrounding the implant (peri-implantitis). This investigation aims to determine the interplay between bacteria and host’s purinergic (extracellular ATP) receptors known to trigger the inflammatory response in order to identify novel biomarkers of early peri-implantitis and innovative treatment targets for this disorder.

Early diagnosis and treatment optimisation will lead to better patient outcomes, less follow-up treatment and reduced costs. The PhD researcher will join a team using multidisciplinary approaches to analyse purinoceptor functions in health and disease. The work will involve collaboration with dental and engineering experts to study different implant designs and it offers training in a range of techniques including microbiology, receptor expression and function, biochemistry, cell culture in vitro and advanced visualisation methods (Portsmouth Zeiss Global Centre).

While the bulk of work will be done in Portsmouth, the PhD student will spend a short period at a collaborating laboratory.
