Abstract

Chronic lung allograft dysfunction (CLAD) is a critical impediment to the long-term survival after lung transplantation. A rat orthotopic lung transplantation model was developed in the early 1970s, and using this model, our laboratory has shown that the immunopathogenesis of CLAD involves both allogeneic immunity and autoimmunity. However, further investigation of CLAD is limited by the scarcity of transgenic and knockout strains. The model most widely used to study CLAD, the mouse model of heterotopic tracheal transplantation, has some incomplete pathophysiologic features of CLAD, which limits the utility of this model. Unlike other solid organ transplants, vascularized and aerated murine lung transplantation has only recently been developed. We have also reported that minor, but not major, histocompatibility antigens mismatch induced the development of CLAD in murine orthotopic lung transplants and that CLAD development was interleukin-17-dependent. This mini-review underscores the history and development of rodent models of CLAD after lung transplant, including the findings from our previous studies. In addition, the future direction of rodent models is also discussed.
