  • Patent number: 6447780
    Abstract: The present invention relates to methods and compositions for eliciting an immune response and the prevention and treatment of primary and metastatic neoplastic diseases and infectious diseases. The methods of the invention comprise administering a composition comprising an effective amount of a complex, in which the complex consists essentially of a heat shock protein (hsp) noncovalently bound to an antigenic molecule. Optionally, the methods further comprise administering antigen presenting cells sensitized with complexes of hsps noncovalently bound to an antigenic molecule. “Antigenic molecule” as used herein refers to the peptides with which the hsps are endogenously associated in vivo as well as exogenous antigens/immunogens (i.e., with which the hsps are not complexed in vivo) or antigenic/immunogenic fragments and derivatives thereof. In a preferred embodiment, the complex is autologous to the individual. In a specific embodiment; the effective amounts of the complex are in the range of 0.

  • Patent number: 6448071
    Abstract: Specificity in immune responses is in part controlled by the selective interaction of T cell receptors with their cognate ligands, peptide/MHC molecules. The discriminating nature of this interaction makes these molecules, in soluble form, good candidates for selectively regulating immune responses. Attempts to exploit soluble analogs of these proteins has been hampered by the intrinsic low avidity of these molecules for their ligands. To increase the avidity of soluble analogs for their cognates to biologically relevant levels, divalent peptide/MHC complexes or T cell receptors (superdimers) were constructed. Using a recombinant DNA strategy, DNA encoding either the MHC class II/peptide or TCR heterodimers was ligated to DNA coding for murine Ig heavy and light chains. These constructs were subsequently expressed in a baculovirus expression system.

Protein “e” and peptides or proteins having a shared epitope, can be used to vaccinate against non-typable (and typable) H. influenzae and to prevent otitis media caused by H. influenzae. For this purpose, protein “e” or derivatives thereof can be produced in native, synthetic or recombinant forms and can be administered alone or in conjunction with other antigens of H. influenzae. Protein “e” can also be used in multivalent vaccines designed for H. influenzae and one or more other infectious organisms.

  • Patent number: 6416956
    Abstract: An isolated DNA of SEQ ID NO: 1 is provided that encodes the transcription factor BP1, which is believed to be a repressor of the &bgr;-globin gene. A host cell that is transformed with a vector that contains the DNA may be used to produce BP1. Vectors having a controllable promoter operably connected to the BP1 open reading frame may be used to transform &bgr;-globin producing cells of patients with sickle cell anemia, thereby providing a treatment. Because BP1 is overexpressed in leukemia and breast cancer cells, acute myeloid leukemia, acute lymphocytic leukemia, and breast cancer can be screened for and diagnosed by determining whether BP1 is overexpressed in cell samples of patients who may have these conditions. An antisense DNA or RNA to the DNA encoding BP1 may be used as a treatment for acute myeloid leukemia, acute lymphocytic leukemia, and breast cancer.

  • Patent number: 6410027
    Abstract: The present invention relates to methods for preparing immunogenic, prophylactically and therapeutically effective complexes of heat shock proteins noncovalently associated with antigenic peptides of cancer cells. The claimed methods comprise the constructing of a cDNA library from cancer or preneoplastic cell RNA, expressing the cDNA library in an appropriate host cell, and recovering the immunogenic complexes from the cells. Large amounts of such immunogenic complexes can be obtained by large-scale culturing of host cells containing the cDNA library. The complexes can be used as a vaccine to elicit specific immune responses against cancer or preneoplastic cells, and to treat or prevent cancer.

  • Patent number: 6406693
    Abstract: Disclosed are the surprising discoveries that aminophospholipids, such as phosphatidylserine and phosphatidylethanolamine, are stable and specific markers accessible on the luminal surface of tumor blood vessels, and that the administration of an anti-aminophospholipid antibody alone is sufficient to induce thrombosis, tumor necrosis and tumor regression in vivo. This invention therefore provides anti-aminophospholipid antibody-based methods and compositions for use in the specific destruction of tumor blood vessels and in the treatment of solid tumors. Although various antibody conjugates and combinations are thus provided, the use of naked, or unconjugated, anti-phosphatidylserine antibodies is a particularly important aspect of the invention, due to simplicity and effectiveness of the approach.

  • Patent number: 6406689
    Abstract: Compositions and methods are provided which can be utilized in active immunization as a prophylactic treatment or a therapeutic treatment for tumors. The compositions are employed as injectable tumor vaccines or as preparations for intratumoral administration and are capable of stimulating immune responses to specific tumor antigens. The tumor vaccines are composed of an antigenic cellular material including a plurality of inactivated tumor cells or tumor cell portions, a depot material, and an immunostimulant adsorbed to the depot material. The depot material with absorbed immunostimulant is mixed with the tumor cells or tumor cell portions to form the vaccine compositions. The preparations for intratumoral administration include the depot material adsorbed immunostimulant without the antigenic cellular material. The immunostimulant adsorbed to the depot material permits release of biologically active quantities of the immunostimulant over a period of time rather than all at once.
