Liver transplantation is currently recognized as the most effective treatment for severe liver diseases. Although survival rates after liver transplantation have improved, rejection of the transplanted liver remains a significant cause of morbidity and transplant failure in patients. Our team previously discovered a close association between high GBP1 expression and acute rejection reactions following liver transplantation. Liver biopsies were conducted on patients who experienced acute rejection or successfully achieved immune tolerance post-transplantation. We confirmed that GBP1 was highly expressed in the acute rejection group after transplantation by Immunohistochemistry. This study aims to confirm that GBP1 promotes acute rejection reactions following liver transplantation through inducing pyroptosis in rat transplanted hepatic macrophages (KCs). We knocked down GBP1 in KCs and examined the extent of pyroptosis and the severity of acute rejection in the transplanted liver post-orthotopic liver transplantation in rats and KCs. These data provide new approaches for the study of liver transplant rejection reactions and identify new targets.

Background: Lung transplantation is a viable lifesaving option for patients with diffuse pulmonary arteriovenous malformations (AVMs). We present a case of diffuse pulmonary AVMs associated with juvenile polyposis and hereditary hemorrhagic telangiectasia (JP-HHT) that was successfully managed by lung transplantation.
Case Presentation: A 19-year-old woman developed severe hypoxemia due to pulmonary AVMs diagnosed at 4 years of age.

Background: Data about the safety of ACEI/ARB use in early (<3 months) posttransplant period are restricted and remain controversial.
Methods: This systematic review and meta-analysis included searches of PubMed, Embase and CENTRAL from inception to 31 November 2023, for studies to compare the safety (transplant outcomes and postoperative complications) of ACEI/ARB with non-ACEI/ARB (other antihypertensive medications) initiation in early post kidney transplant period.
Results: Of 1,247 citations identified, 13 eligible studies involving 1919 patients were enrolled for analyses.
Prevalence and Impact of Cytomegalovirus Primary Infection and Reactivation on Graft Function in Post-Renal Transplant Recipients.

Introduction Cytomegalovirus (CMV) is often associated with mortality and significant morbidity following renal transplantation leading to graft rejection or dysfunction. Primary CMV infection refers to the first detection of the virus in a person who has no prior evidence of CMV exposure before transplantation. CMV has a unique property called latency.

Background: Post-transplantation diabetes mellitus and carbohydrate intolerance (PTDM/iCHO) are complications following solid organ transplantation, which significantly increases the risk of graft loss and mortality. However, data concerning long-term outcomes in paediatric kidney transplant recipients with PTDM/iCHO are scarce. This study aimed to evaluate the risk of graft loss in paediatric kidney transplant recipients with PTDM or iCHO compared with non-PTDM/iCHO.
