  • Publication number: 20110104675
    Abstract: The invention is directed to compositions and methods for the detection of a malignant condition, and relates to the discovery of soluble forms of mesothelin polypeptides, including mesothelin related antigen (MRA). In particular the invention provides a nucleic acid sequence encoding MRA and an MRA variant. The invention also provides a method of screening for the presence of a malignant condition in a subject by detecting reactivity of an antibody specific for a mesothelin polypeptide with a molecule naturally occurring in soluble form in a sample from such a subject, and by hybridization screening using an MRA nucleotide sequence, as well as other related advantages.

  • Publication number: 20040058445
    Abstract: An improved method for ex-vivo generation of tumor-reactive T cells is provided, comprising culturing PBMC from a patient with cancer with autologous tumor cells and magnetic beads which activate T lymphocytes via CD3 in combination with CD28, CD40, or CD28 plus CD40. The invention also provides genes encoding anti-CD3 or anti-4-1BB scFv and methods to transfect cells of neoplastic or normal origin for expression of those genes at their surface. The genes and transfected tumor cells are useful compositions for induction of a tumor-destructive immune response.

  • Publication number: 20040043029
    Abstract: The present invention relates to novel antibodies, antibody fragments and antibody conjugates and single-chain immunotoxins reactive with human carcinoma cells. More particularly, the antibodies, conjugates and single-chain immunotoxins of the invention include: a murine monoclonal antibody, BR96; a human/murine chimeric antibody, ChiBR96; a F(ab′)2 fragment of BR96; ChiBR96-PE, ChiBR96-LysPE40, ChiBR96 F(ab′)2-LysPE40 and ChiBR96 Fab′-LysPE40 conjugates and recombinant BR96 sFv-PE40 immunotoxin. These molecules are reactive with a cell membrane antigen on the surface of human carcinomas. The BR96 antibody and its functional equivalents, displays a high degree of selectivity for carcinoma cells and possess the ability to mediate antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity activity.
