About this Research Topic
Lung transplantation is an increasingly used therapy for end-stage lung diseases. However, the long-term outcomes after lung transplantation remain significantly unsatisfactory compared with those in the recipients of other solid-organ transplant. In the modern era of lung transplantation, the 5-year survival rate is only about 50%. One of the key reasons is the unique anatomic and immunological properties of lungs. They constantly interact with pathogens as well as environmental antigens. Recent advances of innate cells (e.g. monocytes, macrophages and neutrophils etc.) and their critical roles in early graft dysfunction as well as chronic rejection, especially the new knowledge in the field of trained innate immunity and adaptive memory responses, have dramatically changed our understanding of lung immunology and the strategies to achieve long-term graft acceptances.
This Research Topic aims to advance the knowledge of lung transplant immunology, specifically the innate immunity and its trained response, adaptive memory response and heterologous immunity, and their roles in primary graft dysfunction (PGD), acute and chronic rejection, to gain new perspectives of lung transplant protection and to develop novel strategies for long-term graft survival.
We welcome submissions of Original Research, Review, Mini Review on the sub-topics below:
1. Primary graft dysfunction (PGD) after lung transplantation

c. IL-17 and Inflammation
2. Memory of innate cells in lung transplantation
a. Adaptive features of innate immune cells
b. Trained immunity
