Transforming growth factor beta (TGF-beta), a pleiotropic cytokine that regulates cell growth and differentiation, is secreted by many human tumors and markedly inhibits tumor-specific cellular immunity. Tumors can avoid the differentiating and apoptotic effects of TGF-beta by expressing a nonfunctional TGF-beta receptor. We have determined whether this(More)
In 29 of 36 children with fetal alcohol syndrome brainstem auditory-evoked potentials were performed and the auditory threshold was determined. The hearing of patients with a pathologic finding was then subject to a thorough ear-nose-throat examination. Additionally the IQ was determined and an audiolinguistic examination was carried out. Seventy-five % of(More)
Human Epstein-Barr virus-specific T cells were genetically modified to express chimeric receptors specific for human CD19, which is expressed on the cell surface of most B cell malignancies. The receptor-modified EBV-specific T cells can be expanded and maintained long term in the presence of EBV-infected B cells. They recognize autologous EBV-infected(More)
Genetic engineering of human T lymphocytes to express tumor antigen-specific chimeric immune receptors is an attractive means for providing large numbers of effector cells for adoptive immunotherapy. Major mechanisms of tumor escape from immune recognition are efficiently bypassed. Although adoptive transfer of chimeric receptor-expressing peripheral(More)
BACKGROUND No effective therapeutic modalities exist for the treatment of relapsed high risk acute lymphoblastic leukemia (ALL). Adoptive cellular immunotherapy by transfusion of polyclonal donor lymphocytes is not always effective and is limited by cellular cross-reactivity with normal tissues, leading to development of clinical graft-versus-host disease(More)
Induction therapy for childhood acute lymphoblastic leukemia (ALL) traditionally includes prednisone; yet, dexamethasone may have higher antileukemic potency, leading to fewer relapses and improved survival. After a 7-day prednisone prephase, 3720 patients enrolled on trial Associazione Italiana di Ematologia e Oncologia Pediatrica and(More)
BACKGROUND Accumulation of the cytosine arabinoside (ara-C) metabolite ara-C-triphosphate (ara-CTP) in leukemic blast cells is considered to be the main determinant of ara-C cytotoxicity in vitro and in vivo. Retinoids such as all-trans-retinoic acid (ATRA) have been shown to increase the sensitivity of acute myelogenous leukemic (AML) blast cells to ara-C.(More)
Curative therapies for Ewing sarcoma have been developed within cooperative groups. Consecutive clinical trials have systematically assessed the impact and timing of local therapy and the activity of cytotoxic drugs and their combinations. They have led to an increase of long-term disease-free survival to around 70% in patients with localized disease.(More)
