Repair and Regeneration in the Oral Mucosa

Our group’s research is focussed in defining the molecular and cellular control mechanisms involved in impaired human wound healing. From defining the genotypic and phenotypic changes in human fibroblasts associated with disease, we have highlighted the role of  bacteria in modulating these processes.  The group was instrumental in establishing CITER. Having obtained over £10M in external funding since our establishment of the Programme in 1993, we have worked to translate our understanding of the processes of impaired healing and particularly the role of bacterial pathogens in these processes.  The group has welcomed inter-disciplinary research and the PhD and MD programme has seen general surgeons, plastic surgeons, dermatologists, physicians and dentists as postgraduate students.   

This work led to a re-evaluation of how we diagnose and manage bacteria in chronic, non-healing wounds. This work is being translated to clinical practice via the development of  new classes of agents (OligoG and polymer-drug conjugates) which offer the opportunity for new approaches to the management of human disease. We have developed and patented the use of the first oligosaccahride nanomedicines to treat multi-drug resistant gram-negative & biofilm-related infection in man (GB 0909556.3 GB 0909529.0 PCT/GB2010/001098 PCT/GB2010/001096 PCT/GB2010/001097); these agents have succesfully completed Phase 1 clinical studies in humans.
