Background & Aims The liver provides a unique niche of lymphocytes enriched with a large proportion of innate-like T cells. However, the heterogeneity and functional characteristics of the hepatic T-cell population remain to be fully elucidated. Methods We obtained liver sinusoidal mononuclear cells from the liver perfusate of healthy donors and recipients with HBV-associated chronic liver disease (CLD) during liver transplantation. We performed a CITE-seq analysis of liver sinusoidal CD45 + cel

Acute cellular rejection after liver transplantation (LT) can be treated with steroid pulse therapy, but there is no ideal treatment for steroid-resistant acute rejection (SRAR). We aimed to determine the feasibility and potential complications of rabbit anti-thymocyte globulin (rATG) application to treat SRAR in liver transplant recipients. We retrospectively reviewed medical records of 429 recipients who underwent LT at Severance Hospital between January 2010 and March 2015. We compared clinic

The Oxford classification scheme is useful for evaluating chronic graft dysfunction in patients with posttransplantation IgAN. In addition to tubulointerstitial fibrosis, the presence of endocapillary hypercellularity and segmental sclerosis should be included in the pathology report.

Previous studies showed promise of coupling genetically engineered neural stem cells (NSCs) with blood-brain barrier permeable prodrugs as an effective anti-brain tumor therapy. Here, we further advance those findings by testing the suicide gene therapeutic system in syngenic glioblastoma immunocompetent mice. After intracranial injection of HB1.F3.CD, an immortalized human NSC cell line engineered to constitutively produce cytosine deaminase (CD), the prodrug 5-fluorocytosine (5-FC) was adminis

OBJECTIVE: To compare graft survival after living donor liver transplantation (LDLT) in patients receiving graft-to-recipient weight ratio (GRWR) <0.8 versus GRWR≥0.8 grafts and identify risk factors for graft loss using GRWR<0.8 grafts. BACKGROUND: Favorable outcomes after LDLT using GRWR<0.8 grafts were recently reported; however, these results have not been validated using multicenter data. METHODS: This multicentric cohort study included 3450 LDLT patients. Graft survival was compared betwee

Serum bilirubin, a potent endogenous antioxidant, has been associated with decreased risks of cardiovascular disease, diabetes, and kidney disease. However, the effects of serum bilirubin on kidney transplant outcomes remain undetermined. We analyzed 1628 patients who underwent kidney transplantations between 2003 and 2017. Patients were grouped into sex-specific quartiles according to mean serum bilirubin levels, 3-12 months post-transplantation. Median bilirubin levels were 0.66 mg/dL in males

A history of TB is the strongest predictor of post-transplant TB. Therefore, patients with a pre-transplant history of TB should be carefully monitored.

Tacrolimus is the mainstay of immunosuppression in liver transplantation to prevent rejection. However, the clinical use of tacrolimus is complicated by its narrow therapeutic window and significant intra-patient variability (IPV). High tacrolimus IPV is associated with overexposure and adverse effects, including malignancy. The effects of tacrolimus IPV in liver transplant recipients with and without hepatocellular carcinoma (HCC) are unknown. We investigated the association between tacrolimus
