Hybridoma producing monoclonal antibody to proliferating cell nuclear antigen (PCNA/cyclin) (TOB7, IgG1 κ) was newly established. Using TOB7, PCNA was detected in the peripheral blood mononuclear cells (PBMC) in patients with systemic lupus erythematosus (SLE). Forty-four of 58 patients with SLE had PBMC expressing PCNA. The percentage of PCNA-positive PBMC(More)
The structure of the integrated provirus in cell lines established from the cerebrospinal fluid (CSF) of patients with human T-cell leukemia virus type-1 (HTLV-1)-associated myelopathy (HAM) was analyzed. The digestion patterns with 3 restriction endonucleases, Sac I, Eco RI and PstI, of the proviruses integrated in T-lymphoid cell lines derived from the(More)
The expressions of human T-lymphotropic virus type I (HTLV-I) mRNA in the HTLV-I-infected lymphocytes were studied in the peripheral blood of two HTLV-I carriers and of three patients with adult T-cell leukemia (ATL) (acute, chronic and lymphoma types) by in situ hybridization technique using two biotinylated single-stranded oligodeoxynucleotide probes(More)
IgG subclasses of anti-Sm and anti-U1 ribonucleoprotein (U1 RNP) antibodies were determined using a new clone of the anti-IgG2 antibody (HG2-56F). Although the predominance of IgG1 coincided with previous reports, IgG2 anti-Sm and U1 RNP antibodies were detected in numerous patients. IgG3 anti-Sm antibody significantly correlates with joint involvement and(More)
Sjögren's syndrome is not one of the forty-five diseases included in the incurable disease treatment research project funded by the government. However, it is approved as a designated incurable disease for government funded treatment in Tokyo. The criteria of approval are based on diagnostic criteria revised in 1999. Complications and other factors are(More)
A rabbit lymphoid cell line (Ra-1) was established by co-cultivation with a human T-cell line (MT-2) carrying human T-cell leukemia virus (HTLV). The Ra-1 cell line is chromosomally male and is persistently infected with HTLV. Ra-1 cells, with or without mitomycin C treatment, were inoculated intravenously (i.v.) into 3 female rabbits. All 3 animals(More)
BACKGROUND Alpha fetoprotein (AFP) producing gastric cancer is an unusual form of aggressive adenocarcinoma with a complex histological picture, including enteroblastic and hepatoid differentiation. AIMS To investigate the genetic events underlying the phenotypic diversity in AFP producing gastric cancer and the ability of these tumours to produce AFP(More)
The mode of vertical transmission of human T-cell leukemia virus type I (HTLV-I) was investigated by foster-nursing in rabbits. Two of five rabbits born to noninfected mothers and fostered by virus-infected females seroconverted for HTLV-I after 7 weeks, whereas all seven rabbits born to virus-infected mothers and fostered by noninfected females remained(More)
