In order to establish an efficient gammadelta T cell-mediated immunotherapy for hematological malignancies, we attempted to evaluate cytotoxicity against tumor cells by gammadelta T cells, which were generated from blood cells of patients with myeloma and lymphoma by culturing with zoledronate and a low dose of IL-2. Although gammadelta T cells were(More)
In order to establish the method of generating powerful gammadelta T cells for anti-tumor immunotherapy, we investigated the effects of monocyte-derived dendritic cells (mo-DCs) on anti-tumor cytotoxicity of expanded gammadelta T cells. Activation of gammadelta T cells co-cultured for 2-3 days with immature or mature mo-DCs was evaluated by CD69 expression(More)
Fibronectin was isolated from human plasma by affinity chromatography with gelatin-coupled Sepharose 4B. Anti-fibronectin antiserum was prepared using rabbits, and human liver biopsy specimens at various stages of fibrosis were investigated for distribution of fibronectin by the indirect immunofluorescence technique. Fibronectin was absent in liver(More)
We describe a patient with acute lymphoblastic leukemia (ALL) in whom hemopoiesis recovered after an autologous marrow graft purged by in vitro hyperthermia. A 17-year-old woman was diagnosed as having ALL in April 1985. After clinical remission was induced, marrow cells were harvested. The marrow cells were treated with hyperthermia at 42.0 degrees C for 1(More)
Cells of the hematopoietic cell line K562 were synchronized by three different methods: single aphidicolin treatment, thymidine treatment followed by hydroxyurea exposure, and double hydroxyurea treatment. The synchronized cells were transfected via electroporation with plasmid pMoZtk, which contains the beta-galactosidase gene, using a square wave pulse(More)
We report the second case of neonatal alloimmune thrombocytopenia due to anti-human platelet antigen (HPA)-3b (Bak(b)) antibody. The infant was severely affected with intracranial haemorrhage. Most importantly, we were able to detect this antibody only by using fresh, unfixed platelets as antigen. This antibody was detectable neither by conventional mixed(More)
A novel cell line (KH88) was established from a patient with chronic myelogenous leukemia in blastic crisis. The leukemic blasts had the features of undifferentiated blasts with basophilic agranular cytoplasm and they were focally positive for acid phosphatase and alpha-naphthyl acetate esterase. CD36, CD33, HLADR, and CD71 were expressed on the surfaces of(More)
A 67-year-old man was admitted in October 1987 with complaints of nausea, headache, dizziness and speech disturbance. Hematological examination showed pancytopenia. Bone marrow aspiration failed with a dry tap. A month later, the second aspiration showed hypocellular marrow containing 18.2% of lymphoma cells. Physical examination showed splenomegaly and(More)
