Under anaerobic conditions, cells of Entamoeba histolytica grown with bacteria produce H2 and acetate while cells grown axenically produce neither. Aerobically, acetate is produced and O2 is consumed by amebae from either type of cells. Centrifuged extracts, 2.4 x 106 x g x min, from both types of cells contain pyruvate synthase (EC and an acetate(More)
Transforming growth factor beta (TGF-beta) is a potent immunosuppressive cytokine that is produced by neoplastic and normal cells. It has not been demonstrated directly, however, that TGF-beta can inhibit antigen-specific T-cell responses to tumor cells in vitro. We show here that generation of antitumor cytotoxic T-lymphocyte (CTL) activity in(More)
BACKGROUND Current antihumoral therapies in transplantation and autoimmune disease do not target the mature antibody-producing plasma cell. Bortezomib is a first in class proteosomal inhibitor, that is Food and Drug Administration approved, for the treatment of plasma cell-derived tumors that is multiple myeloma. We report the first clinical experience with(More)
Antibody-mediated rejection (AMR) is an uncommon, but challenging type of rejection after solid organ transplantation. We review three cases of AMR in ABO-compatible liver transplant recipients. These cases were characterized by severe acute rejection resistant to steroids and antithymocyte globulin, histologic evidence of plasma cell infiltrates, C4d(More)
Isotope studies indicate that hexose-to-pentose interconversion by axenic Entamoeba histolytica conserves the C-1 and C-6 hexose carbon atoms. Transketolase was readily identified in amoebal extracts, and transaldolase could not be demonstrated. However, sedoheptulose 7-phosphate is a substrate for the PPi-dependent amoebal phosphofructokinase, and(More)
BACKGROUND We used a solid-phase assay to identify human leukocyte antigen (HLA) Class I and II specificities in highly reactive sera, and applied this information to predict crossmatch outcome with greater than 90% accuracy. METHODS Sera from 20 highly sensitized end-stage renal disease patients reactive to 70-100% of HLA Class I and II antigen panel(More)
In a previous study, we found that 92% of patients with chronic rejection had donor-specific human leukocyte antigen antibodies (DSAs), but surprisingly, 61% of comparator patients without rejection also had DSAs. We hypothesized that immunoglobulin G (IgG) subclasses were differentially distributed between the 2 groups. A modified single-antigen bead assay(More)
BACKGROUND In recent years, transplantation of islets and pancreas has become a viable option for patients debilitated with type I diabetes. The success of islet transplantation has been attributed to the ability to isolate high quality islets for transplantation and capacity to maintain the recipient's immunosuppressive levels within a specific target(More)
Cells required for the in vitro generation of syngeneic cytotoxic T-lymphocytes (CTL) against the P815 mastocytoma in the DBA/2 mouse strain were investigated. For both immune and tumor-bearing host spleen cells, CTL effector cells were eliminated by treatment with anti-Thy1.2, anti-Lyt1.1, or anti-Lyt2.1 and C', but were resistant to anti-L3T4 (GK1.5).(More)
