The University of Sheffield Faculty of Medicine, Dentistry & Health Department of Infection & Immunity Using in vivo imaging in transparent zebrafish to understand the fate of inflammatory cells Supervisor: Professor Stephen Renshaw & Dr Philip Elks Project: Being able to see every inflammatory cell as inflammation proceeds is a uniquely powerful way to understand this fundamentally important biological process. Using transparent zebrafish expressing fluorescent proteins in various immune cells, we have pioneered new ways to see and understand immunity where it counts – in living systems. Using these systems we have shown how neutrophils are recruited as the body’s first line of defence against injury and invading pathogens. Once the infectious challenge has been neutralised, however, it is critical that inflammation resolves and neutrophils are removed, since chronic inflammation leads to tissue damage and scarring – important in many diseases. Previously, highly successful PhD students in the lab have shown that resolution of neutrophilic inflammation can be brought about by a new drug treatment they identified (Robertson, Science Translational Medicine in press), which causes neutrophils to migrate away from the inflammatory site, a process known as reverse migration (Elks et al., 2011). The two most interesting questions however remain unanswered. In this PhD studentship, the successful candidate will use our unique approaches to investigate (1) how neutrophil removal from wounds is controlled at a molecular level and (2) what happens to neutrophils that have reverse migrated away from wounds. Are reverse migrated neutrophils fully functional? Do they carry with them some memory of their inflammatory encounter? This is likely to reveal exciting information of relevance to our understanding and treatment of inflammatory diseases. Students in our labs are well looked after and get fantastic training in cutting-edge microscopy techniques, molecular biology and in vivo modelling.
