Mice: Suppression by Antibody to Pluripotent K-562 Leukemia Cells Involves Direct Cytolysis and Effector Cells

چکیده
Six human hematopoetic cell lines were successfully heterotransplanted into athymic (nude) and asplenic-athymic (Iasat) neonatal mice. The tumors arising from leukemia and lymphoma cells could then be serially transplanted into adult nude mice. Seven days after the fourth serial mouse passage, each mouse was treated with goat immune gamma globulin against K-562 cells. One control group was treated similarly, but with nonimmune (normal) gamma globulin. while another control group was not treated. The goat gamma globulin was not toxic for nude and lasat mice, and the immune, but not the normal, gamma globulin suppressed local subcutaneous growth of myelosarcomas, Iymphosarcomas, and Burkitt lymphoma cells. On the other

Introduction: Chronic Myelogenous Leukemia (CML) is a malignant disease. Different drugs have been suggested for the treatment of leukemia, but none of them has resulted in complete remission. Recently scorpion toxins have been reported to have anticancer activity on several cell lines. In the present study, the effects of Hemiscorpius Lepturus scorpion was evaluated on K-562 cell line as an ex...
متن کاملHuman natural killer cells do not inhibit growth of Cryptococcus neoformans in the absence of antibody.
The interaction between human natural killer (NK) cells and yeast cells of Cryptococcus neoformans was investigated because experiments in mice indicated that NK cells inhibited the growth of C. neoformans. Strains of C. neoformans serotype A that differed in both resistance to alveolar macrophages and the size and composition of their capsules were evaluated. Human NK cells, which were isolate...
متن کاملMHC-restricted minimal regulatory circuit initiated by a class II- autoreactive T cell clone
The in vivo administration of a self-class II-reactive Th clone MS202 derived from C3H into syngeneic mice resulted in the suppression of both primary and early secondary antibody responses against T cell-dependent antigens. The suppression was due to the generation of antigen-nonspecific Ts cells in the recipient, as the splenic T cells from the mice treated with MS202 were able to strongly su...
متن کاملGardenia jasminoides extracts and gallic acid inhibit lipopolysaccharide-induced inflammation by suppression of JNK2/1 signaling pathways in BV-2 cells
Objective(s): Gardenia jasminoides Ellis (GJ, Cape Jasmine Fruit, Zhi Zi) has been traditionally used for the treatment of infectious hepatitis, aphthous ulcer, and trauma; however, the direct evidence is lacking. Materials and Methods:We investigated the effect of the GJ extract(GJ) and gallic acid (GA) on lipopolysaccharide (LPS) induced inflammation of BV-2 microglial cells and acute liver ...
