Alloantisera (anti-donor and anti-recipient alloantiserum) were prepared by skin grafting followed four inoculations of 1 x 107 splenocytes. These alloantisera were cytotoxic ( x 64) to target cells specifically. Anti-recipient alloantiserum was effective on enhancing skin graft survival in mice as same as anti-donor alloantiserum, when administered on the operative day, second postoperative da...

The natural history of hepatitis C virus (HCV) among patients after renal transplantation (RT) remains incompletely defined. We conducted a systematic review of the published medical literature on the impact of hepatitis C antibody status on survival of patients who received RT. We used the random effects model of DerSimonian and Laird to generate a summary estimate of the relative risk (RR) fo...

Transfer of recipient regulatory T cells (Tregs) induces mixed chimerism and tolerance in an irradiation-free bone marrow (BM) transplantation (BMT) model involving short-course co-stimulation blockade and mTOR inhibition. Boosting endogenous Tregs pharmacologically in vivo would be an attractive alternative avoiding the current limitations of performing adoptive cell therapy in the routine cli...

CD40-CD40L costimulatory interactions are crucial for allograft rejection, in that treatment with anti-CD40L mAb markedly prolongs allograft survival in several systems. Recent reports indicate that costimulatory blockade results in deletion of graft-reactive cells, which leads to allograft tolerance. To assess immunologic parameters that were influenced by inductive CD40-CD40L blockade, cardia...

This study aims to evaluate the efficacy of HBV vaccination as an alternative preventive measure against de novo HBV infection in pediatric living donor liver transplantation (LDLT). Sixty recipients were enrolled in this study. Thirty received grafts from anti-HBc(+) donors, and another 30 received grafts from anti-HBc(-) donors. HBV vaccine was given pretransplant to every candidate. Posttran...

The angiotensin II type 1 receptor (AT1R) is an emerging target of functional non-HLA antibodies (Ab). We examined the potential of determining the degree of presensitization against AT1R as a risk factor for graft survival and acute rejection (AR). The study included 599 kidney recipients between 1998 and 2007. Serum samples were analyzed in a blinded fashion for anti-AT1R antibodies (AT1R-Abs...

Donor shortage remains the single most important factor limiting the success of transplantation medicine. In face of this unrelenting pressure, otherwise prohibitive immunological barriers are increasingly accepted, such as ABO incompatibility of a kidney from an available living donor. Treatment protocols for such situations involve varying combinations of B-cell depletion, removal of isohemag...

PURPOSE To develop and compare effective strategies for depleting graft-derived passenger leukocytes that include antigen-presenting cells from corneal buttons and to assess the effectiveness of this strategy in promoting graft survival using a high-risk (HR) model of corneal transplantation. METHODS Corneal buttons harvested from C57BL/6 mice were used in three ex vivo strategies of passenge...

We have recently shown that the use of allogeneic granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood hematopoietic stem cell transplantation (PBHSCT), as compared with bone marrow transplantation (BMT), is associated with increased titers of antibodies (Abs) directed against red blood cell ABO antigens. To further evaluate the influence of a G-CSF-mobilized PBHSCT graft on...
