Research Interests:
Lung transplantation is the only definitive therapy for many forms of end stage lung diseases, such as cystic fibrosis, pulmonary fibrosis and COPD. However, acute rejection and chronic rejection, manifested as obliterative bronchiolitis/bronchiolitis obliterans syndrome (OB/BOS), are still impediments to the long term survival of lung transplant recipients. The incidence of acute rejection remains over 50% in the first year, and the five year graft survival is still less than 50% due primarily to the development of OB/BOS. No effective treatments prevent the onset or significantly delay the progression of OB/BOS. There is a clear need for basic science research to identify novel targets for therapy and improve outcomes. Our research uses both human and mouse models to study the immunology of allograft rejection after lung transplantation. We have a model of acute T cell mediated rejection in the lung and have found that the T cell costimulatory molecule ICOS regulates the function of T regulatory cells (CD4+Foxp3+) in the resolution of acute lung inflammation. Currently we are investigating the mechanisms by which ICOS affects the function of T regulatory cells. Furthermore, we have an ongoing collaboration with Dr. David Wilkes and his laboratory to study the T cells mediating allograft rejection and the development of obliterative bronchiolitis using a mouse model of orthotopic lung transplantation. We are also developing a lung transplant biobank using specimens collected from humans being considered for lung transplantation. We plan to use this resource to find novel pathways involved in regulating the immune response after transplantation and contributing to bronchiolitis obliterans syndrome, the major cause of allograft failure after lung transplant. In addition we are collaborating with several other institutions in the midwest to establish a consortium of lung transplant research institutions focused on researching the immunology of human lung transplantation.
