Fanconi anemia (FA) is a genetic disorder that leads to aplastic anemia and birth defects and predisposes to cancer. FA cells exhibit characteristic hypersensitivity to DNA cross-linking agents such as mitomycin C (MMC), and FANCG is one of six known FA gene products. By immunocytochemical analysis of transfected cells, we discovered that although FANCG(More)
There is growing interest in using MRI to track cellular migration. To date, most work in this area has been performed using ultra-small particles of iron oxide. Immune cells are difficult to label with iron oxide particles. The ability of adoptively infused tumor specific T cells and N cells to traffic to the tumor microenvironment may be a critical(More)
PURPOSE Telomerase is an attractive target antigen for cancer immunotherapies because it is expressed in >85% of human tumors but is rarely found in normal tissues. A HLA-A*0201-restricted T-cell epitope was previously identified within telomerase reverse transcriptase hTERT:540-548. This peptide was reported to induce CTL that recognized tumor cells and(More)
Cellular inactivation through killer immunoglobulin-like receptors (KIRs) may allow neoplastic cells to evade host natural killer (NK) cell-mediated immunity. Recently, alloreactive NK cells were shown to mediate antileukemic effects against acute myelogenous leukemia (AML) after mismatched transplantation, when KIR ligand incompatibility existed in the(More)
Allogeneic haematopoietic cell transplantation (HCT) can cure a variety of non-malignant haematological disorders. Although transplant outcomes for selected patients with severe aplastic anaemia (SAA) and paroxysmal nocturnal haemoglobinuria (PNH) have improved, older age, allo-immunisation from transfusions, prior immunosuppressive therapy and a prolonged(More)
OBJECTIVE Green fluorescent protein (GFP) has been used to monitor and select cells transduced with vectors encoding other transgenes of interest. We investigated the immunogenic nature of GFP in humans and further explored whether this xenoprotein could be used as a functional adjuvant to enhance T-cell immunity to the melanoma tumor antigen MART1.

Significant engraftment variability occurs among patients following nonmyeloablative hematopoietic cell transplantation. We analyzed the impact of multiple factors on donor myeloid and T-cell engraftment in 36 patients with metastatic tumors undergoing cyclophosphamide/fludarabine-based conditioning. Higher CD34(+) doses facilitated donor myeloid(More)
PURPOSE Patients with non-Hodgkin's lymphoma (NHL) who do not achieve a complete response (CR) after induction chemotherapy or who relapse after achieving a CR are rarely cured of their disease by the usual salvage therapy. Success of high-dose cytotoxic therapy with an autologous bone marrow transplant (AuBMT) is limited. We describe the results of a(More)
We evaluated the potential role of photoradiation therapy with a benzoporphyrin derivative, monoacid ring A (BPD-MA), and dihematoporphyrin ether (DHE), for the ex vivo purging of residual tumor cells from autologous bone marrow (BM) grafts. BPD-MA and DHE photosensitizing activity was tested against two human large-cell lymphoma cell lines and(More)
