Bovine leukaemia virus (BLV) is an oncogenic retrovirus that causes B-cell lymphocytosis and in the terminal stage of the disease lymphosarcoma. The comparison of the previously published BLV provirus sequence from Belgium, Australia and Japan showed that the protease gene (prt) of the Australian
A new trypsin-like serine protease was cloned from both a murine cytotoxic T lymphocyte and a human PHA-stimulated peripheral blood lymphocyte cDNA library. In both the mouse and human system, this transcript had a T cell- and NK-specific distribution, being detected in cytotoxic T lymphocytes
Enzymaticaly homogeneous fractions of lymphocytes, monocytes, and neutrophils were isolated by zonal centrifugation from peripheral blood of a patient with hairy cell leukemia, or leukemic reticuloendotheliosis, LRE,(with leukopenia, neutropenia, lymphocytosis, and massive splenomegaly). To detect
Pertussigen (Ptx), referred to by many different names, including pertussis toxin, was separated into five polypeptide subunits by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) using a discontinuous Tris-glycine buffer system. Under non-reducing conditions, the apparent
Stimulation of normal rat splenic T cells with pertussigen (lymphocytosis-promoting factor, LPF, from Bordetella pertussis) resulted in the release of a soluble factor that enhanced the glycosylation of IgE-binding factors during their biosynthesis. The soluble factor was detected by the ability of
Fc gamma RIII (CD16), a receptor for complexed IgG, is encoded by two very homologous genes: Fc gamma RIIIA and Fc gamma RIIIB. NK cells and macrophages express Fc gamma RIIIa, whereas only neutrophils constitutively express Fc gamma RIIIb. In a previous study we found that soluble (s)Fc gamma RIII
Glycosylation-enhancing factor (GEF) and IgE-potentiating factor were detected in culture supernatants of rat mesenteric lymph nodes (MLN) cells obtained 14 days after infection with Nippostrongylus brasiliensis (Nb), but not in supernatants of MLN cells of 8-day Nb-infected rats. Both factors were
Stimulation of normal rat splenic T cells with pertussigen (lymphocytosis-promoting factor from Bordetella pertussis) resulted in the release of a soluble factor that enhanced the assembly of N-linked oligosaccharides to IgE-binding factors during their biosynthesis. The glycosylation-enhancing
B-cell Chronic Lymphocytic Leukemia (B-CLL) is the most common hematological disorder among middle-aged/elderly people in the Western countries. We have shown earlier that B-CLL cells exhibit elevated total amount and available activity of µ-calpain, belonging to a family of ubiquitous, strongly
