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)
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)
In this study, the expression of silencing RhoA gene in gastric MGC-803 Cells was investigated, in order to discuss the effect of RhoA gene on cell proliferation, cell cycles and tumor migration. SiRNA sequence of RhoA gene was designed and synthesized; MGC-803 cells were transfected by Lipofectamine(TM2000). The expression of RhoA gene in mRNA and protein(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)
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)
NOD-like receptors play a crucial role in host defense against intestinal infection. We explored the regulatory effects of berberine on NLRs during the intestinal mucosal damaging process in rats. Male Sprague-Dawlay (SD) rats were treated with berberine for 5d before undergoing cecal ligation and puncture (CLP) to induce polymicrobiol sepsis. The(More)
Our previous study has shown berberine prevents damage to the intestinal mucosal barrier during early phase of sepsis in rat through mechanisms independent of the NOD-like receptors signaling pathway. In this study, we explored the regulatory effects of berberine on Toll-like receptors during the intestinal mucosal damaging process in rats. Male(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)
