We transplanted kidneys from alpha1,3-galactosyltransferase knockout (GalT-KO) pigs into six baboons using two different immunosuppressive regimens, but most of the baboons died from severe acute humoral xenograft rejection. Circulating induced antibodies to non-Gal antigens were markedly elevated at rejection, which mediated strong complement-dependent(More)
Although uncontrolled inflammatory response plays a central role in the pathogenesis of acute lung injury (ALI), the precise molecular mechanisms underlying the development of this disorder remain poorly understood. SOCS3 is an important negative regulator of IL-6-type cytokine signaling. SOCS3 is induced in lung during LPS-induced lung injury, suggesting(More)
BACKGROUND Post- endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common and most severe complication associated with diagnostic and therapeutic ERCP. A multivariate analysis of risk factors for PEP is essential for identifying patients at high risk and subsequently choosing other suitable diagnoses. METHODS Pertinent(More)
In current study, we investigated the role of liriodendrin, a constituent isolated from Sargentodoxa cuneata (Oliv.) Rehd. Et Wils (Sargentodoxaceae), in cecal ligation and puncture (CLP)-induced acute lung inflammatory response and injury (ALI). The inflammatory mediator levels in bronchoalveolar lavage fluid (BALF) were determined by enzyme-linked(More)
BACKGROUND Porcine Sertoli cells have an inherent resistance to human xenoreactive antibody and complement-mediated lysis, however, the mechanisms of protection are still unclear. METHODS Neonatal porcine Sertoli cells (NPSCs) were isolated from testes of 10 to 15-day-old piglets. Immortalized porcine aortic endothelial cells (iPECs) were used as control(More)
BACKGROUND In addition to possessing immune privileged properties, Sertoli cells are known to actively suppress responses to cotransplanted cells. An important question is whether this "bystander suppression" is limited to cells of the same origin as the Sertoli cells or whether suppression extends to unrelated cells. METHODS Neonatal porcine Sertoli(More)
BACKGROUND PG490-88 is a water soluble, semisynthetic derivative of a novel compound PG490 (triptolide) purified from the Chinese herb Tripterygium Wilfordii Hook F. In this study, we evaluated the immunosuppressive effect of PG490-88 alone or combined with FK506 in a dog renal transplantation model. METHODS Recipient and donor male beagle dogs were(More)
AIM To compare the preservation of non-heart-beating donor (NHBD) livers in cold histidine-trytophan-ketoglutarate (HTK) solution and extracorporeal liver perfusion (ECLP). METHODS Livers harvested from healthy pigs were stored for 10 h in cold HTK solution (group A, n = 4) or perfused with oxygenated autologous blood at body temperature (group B, n = 4).(More)
CCAAT/enhancer binding protein γ (C/EBPγ) is a member of the C/EBP family of transcription factors, which lacks known activation domains. C/EBPγ was originally described as an inhibitor of C/EBP transactivation potential. However, previous study demonstrates that C/EBPγ augments the C/EBPβ stimulatory activity in lipopolysaccharide induction of IL-6(More)
In xenotransplantation, donor endothelium is the first target of immunological attack. Activation of the endothelial cell by preformed natural antibodies leads to platelet binding via the interaction of the glycoprotein (GP) Ib and von Willebrand factor (vWF). TMVA is a novel GPIb-binding protein purified from the venom of Trimeresurus mucrosquamatus. In(More)
