The impact of donor-specific HLA alloantibodies (DSA) on short- and long-term liver transplant outcome is not clearly defined. While it is clear that not all levels of allosensitization produce overt clinical injury, and that liver allografts possess some degree of alloantibody resistance, alloantibody-mediated adverse consequences are increasingly being recognized. To better define the current...
2-Aminoethylisothiouronium bromide (AET) increases the sensitivity of blood cells to complement-mediated immune lysis. We compared the sensitivities of untreated or AET-treated platelets to immune lysis induced by different types of platelet antibody in the 51Cr platelet lysis test. AET platelets were 8-16 times more sensitive to autoantibody and alloantibody, but 8-16 times less sensitive to d...
Anti-CD154 variably prolongs allograft survival in nonhuman primates. Rodent studies suggest that adding pretransplant donor-specific transfusion (DST) and/or rapamycin to anti-CD154 improves survival. The CD154-specific Ab IDEC-131 was tested alone and in combination with rapamycin for its ability to inhibit rhesus MLRs. The ability of the Ab to block endothelial activation was also assessed. ...
BACKGROUND AND OBJECTIVES Transplant glomerulopathy (TGP) has been proposed to be a component of chronic antibody-mediated rejection (AMR). We have studied 36 patients with TGP and 51 patients with chronic allograft nephropathy (CAN) but without TGP for C4d staining and donor-specific anti-HLA antibodies (DSA) to investigate the alloantibody-mediated mechanisms. DESIGN, SETTING, PARTICIPANTS,...
Fcγ receptors (FcγR) provide important immunoregulation. Targeting inhibitory FcγRIIb may therefore prolong allograft survival, but its role in transplantation has not been addressed. FcγRIIb signaling was examined in murine models of acute or chronic cardiac allograft rejection by transplanting recipients that either lacked FcγRIIb expression (FcγRIIb(-/-)) or overexpressed FcγRIIb on B cells ...
Background The major treatment for thalassemia is a transfusion. The present study aimed to determine the frequency of erythrocyte alloantibodies and the relevant factors among the patients with thalassemia major in Kermanshah city, Iran. ...
