Summary
Organ transplantation has become a feasible option for many end-stage clinical conditions, including advanced lung disease. However, despite often dramatic short term successful outcomes, late graft dysfunction due to chronic rejection remains a major obstacle to long-term success. This is particularly the case in lung transplantation despite the use of potent broad spectrum immunosuppressive agents.

However, despite often dramatic short term successful outcomes, late graft dysfunction due to chronic rejection remains a major obstacle to long-term success. This is particularly the case in lung transplantation despite the use of potent broad spectrum immunosuppressive agents. The three major risk factors that have been identified for chronic rejection following lung transplantation are acute rejection episodes diagnosed on lung biopsy, reactivation of the ubiquitous human DNA virus CMV and persistent lymphocytosis in the transplanted lung suggesting that potent broad spectrum immunosuppression may have both beneficial and harmful effects in lung transplant recipients. This proposal will apply sensitive new immunological techniques to detect and quantitate each of these risk factors at a sub-clinical level with a view to delineating their relationship with each other and with the development of chronic rejection following lung transplantation. This information will help unravel the pathogenesis of chronic rejection in lung transplant recipients and improve clinical management decisions in these patients and therefore long term health outcomes.Read moreRead less
Clinical Implications Of Trans-kingdom Microbial Interactions In The Transplanted Lung

Summary
Lung transplantation is a critical requirement for people with severe lung diseases. The lung is constantly exposed to bugs and viruses, which reside in the airways, and can be both beneficial or detrimental for lung health. This interaction between the immune system and these bugs can influence the health and longevity of the lung transplant. We aim to discover how we could target these interactions to improve the long-term success of lung transplantation.

Summary
The immune system is critical in controlling common viral infections in healthy individuals. When transplanting foreign solid organs into patients with end-stage lung disease the immune systemÍs activity is decreased via the immunosuppressive drugs to enable graft acceptance. In some patients the immune response can detect similarities between previously encountered viruses and the foreign organ, leading to life-threatening health problems through either rejection episodes and/or graft loss.
