Severe combined immunodeficient (Scid) mice inoculated with the human (t(14;18)-positive B cell lines DoHH2 and BEVA develop lethal systemically disseminated lymphoma (de Kroon et al., Leukemia 8:1385, and Blood 80 [suppl 1]:436). These models were used to study the therapeutic effect of rat-anti-human CD52 (Campath-1G) or CD45 monoclonal antibodies (mAbs)(More)
Minor histocompatibility (mH) antigens appear to play a major role in bone marrow transplantation (BMT) using HLA-identical donors. Previously, we reported the isolation of major histocompatibility complex (MHC)-restricted mH antigen-specific cytotoxic T lymphocytes (CTL) from patients with graft-vs.-host disease or rejection after HLA-identical BMT. We(More)
Recently, we have obtained evidence in favor of a structural interaction between the epidermal growth factor (EGF) receptor and the Triton X-100-insoluble cytoskeleton of epidermoid carcinoma A431 cells. Here we present a further analysis of the properties of EGF receptors attached to the cytoskeleton. Steady-state EGF binding studies, analyzed according to(More)
Mice with severe combined immunodeficiency (SCID) provide an in vivo model for studying interactions between human tumor cells and effector cells of the immune system. We studied the behavior of human alloreactive cytotoxic T lymphocytes (CTLs) in SCID mice, including the migration pattern of CD8+ or CD4+ CTL clones to various murine tissues, their(More)
The dissemination pattern of a human non-Hodgkin's lymphoma (NHL) B cell line (DoHH2) carrying the t(14;18) translocation was analyzed in severe combined immunodeficient (SCID) mice, using different routes of administration. When engrafted intraperitoneally (i.p.) the DoHH2 cells showed a local infiltration into intra- and retroperitoneal mouse tissues, and(More)
The severe combined immunodeficient (SCID) mouse model is an important tool with which to study new strategies for treating hematologic neoplasia. For these experiments, a large number of human cell lines growing in SCID mice are a prerequisite. We describe a new Epstein-Barr virus (EBV)-positive B cell line, designated BEVA, with a complex karyotype(More)
An indirect fluorescent antibody test was used successfully for the serodiagnosis of experimental Anaplasma infections in cattle. Specific antibodies were detected three to ten days after anaplasma bodies were found in the blood, and persisted at least 15 weeks post-infection. An American and an African stock of A. marginale were used to prepare antigens,(More)
