Lung transplantation, a critical intervention for end-stage lung diseases, is frequently challenged by post-transplant complications. Indeed, primary graft dysfunction, anastomotic complications, infections and acute and chronic rejections pose significant hurdles in lung transplantation. While evidence regarding the role of airway epithelium after lung transplantation is still emerging, its importance is becoming increasingly recognised. This review looks at the complex involvement of airway epithelium in various post-transplant complications, while emphasising the utility of airway epithelial culture as a research model. In summary, by elucidating the involvement of airway epithelium in each post-transplant complication and explaining these intricate processes, the review aims to guide specific future research efforts and therapeutic strategies aimed at improving lung transplant outcomes and enhancing patient care.
