    • The present invention provides methods for inhibiting interleukin-3 receptor-expressing cells, and, in particular, inhibiting the growth of such cells by using a diphtheria toxin-human interleukin-3 conjugate (DT-IL3) that is toxic to cells expressing the interleukin-3 receptor. In preferred embodiments, the DT-IL3 conjugate is a fusion protein comprising amino acids 1-388 of diphtheria toxin fused via a peptide linker to full-length, human interleukin-3. In certain embodiments, the methods of the present invention relate to the administration of a DT-IL3 conjugate to inhibit the growth of cancer cells and/or cancer stem cells in humans, which cells express one or more subunits of the interleukin-3 receptor. Exemplary cells include myeloid leukemia cancer stem cells. In other embodiments, the methods of the present invention relate to ex vivo purging of bone marrow or peripheral blood to remove cells that express one or more subunits of the interleukin-3 receptor such that the purged bone marrow or peripheral blood is suitable, e.g., for autologous stem cell transplantation to restore hematopoietic function.
    • 本发明提供了抑制白细胞介素-3受体表达细胞的方法,特别是通过使用对表达白介素的细胞有毒性的白喉毒素 - 人白细胞介素-3缀合物(DT-IL3)来抑制这些细胞的生长 -3受体。 在优选的实施方案中,DT-IL3缀合物是包含通过肽连接体融合到全长人白细胞介素-3的白喉毒素的氨基酸1-388的融合蛋白。 在某些实施方案中,本发明的方法涉及施用DT-IL3缀合物以抑制人类癌细胞和/或癌干细胞的生长,所述细胞表达白细胞介素-3受体的一个或多个亚单位。 示例性细胞包括骨髓性白血病癌症干细胞。 在其它实施方案中,本发明的方法涉及骨髓或外周血的离体清除以去除表达白细胞介素-3受体的一个或多个亚基的细胞,使得被清除的骨髓或外周血适合,例如, 用于自体干细胞移植以恢复造血功能。

    • Immunotoxins comprising a cytotoxic moiety and an antigen binding portion selected from the group consisting of Fab, Fab' and F(ab').sub.2 fragments of a monoclonal antibody, which binds to human ovarian cancer tissue, having one of the following capabilities are claimed: cytotoxic ID.sub.50 of about 10 nM or less against human ovarian cancer cells, retardation of human ovarian cancer tumor growth in mammals, or extension of survival of a mammal carrying a human ovarian cancer tumor. Antigens or epitopes to which the monoclonal antibodies bind are identified and characterize the immunotoxins. In a preferred embodiment an immunotoxin comprising at least an antigen binding portion of a monoclonal antibody, which binds to human transferrin receptor, but does not block binding of transferrin to the receptor, is described and claimed. Immunotoxin comprising the F(ab').sub.2 region of the antitransferrin monoclonal antibody are also claimed.Methods of killing human ovarian cancer cells, retarding the growth of human ovarian cancer tumors in mammals and extending the survial of mammals carrying human ovarian cancer tumors are claimed.
