Abstract: The invention discloses compositions, combination therapies and methods of treating B-cell lymphomas and leukemias, as well as other CD40+ malignancies. The primary active agent of the composition is an anti-CD40L antibody or other CD40L antagonist that inhibits CD40-CD40L interaction. Compositions may additionally contain or utilize any one or more of the following in combination for the treatment of said disease: anti-CD20 antibodies, chemotherapeutic agents, chemotherapy cocktails, and radiotherapy.

Abstract: Methods and compositions useful for inducing a cytotoxic T lymphocyte response (CTL) in a human or domesticated or agriculturally important animal. The method includes the steps of providing the antigen to which the CTL response is desired and providing an antigen formulation which comprises, consists, or consists essentially of two or more of a stabilizing detergent, a micelle-forming agent, and an oil. This antigen formulation is preferably lacking in an immunostimulating peptide component, or has sufficiently low levels of such a component that the desired CTL response is not diminished. This formulation is provided as a stable oil-in-water emulsion.

Abstract: The present invention provides a process for high yield regioselective synthesis of DTPA derivatives that eliminates the need for ion exchange chromotographic separation of intermediates. Moreover, as this process yields a single regioisomer of the chelate, it provides for the regiospecific synthesis of desired chelates useful as radiolabeling agents.

Abstract: Methods and compositions useful for inducing a cytotoxic T lymphocyte response (CTL) in a human or domesticated or agriculturally important animal. The method includes the steps of providing the antigen to which the CTL response is desired and providing a microfluidized antigen formulation which comprises, consists, or consists essentially of two or more of a stabilizing detergent, a micelle-forming agent, and an oil. This antigen formulation is preferably lacking in an immunostimulating peptide component, or has sufficiently low levels of such a component that the desired CTL response is not diminished. This formulation is provided as a stable oil-in-water emulsion.

Abstract: Disclosed herein are fully impaired consensus Kozak sequences which are most typically used with dominant selectable markers of transcriptional cassettes which are a part of an expression vector. These vectors are most typically utilized in the expression of proteins in mammalian expression systems. As defined, disclosed and claimed herein, a "fully impaired consensus Kozak" comprises the following sequence: ##STR1## where "x" is a nucleotide selected from the group consisting of adenine (A), quanine (G), cytosine (C) or thymine (T)/uracil (U); "Py" is a pyrimidine nucleotide, ie C or T/U; "ATG" is a codon encoding for the amino acid methionine, the so-called "start" codon; and -3 and +1 are directional reference points, vis-a-vis ATG, ie -3 is meant to indicate three nucleotides upstream of ATG and +1 is meant to indicate one nucleotide downstream of ATG. Dominant selectable markers further comprising artificial intronic insertion regions are further disclosed.

Abstract: Chimeric antibodies specific to human CD4 antigen, DNA encoding, pharmaceutical compositions containing and use thereof as therapeutic agents are taught. These chimeric antibodies contain Old World monkey variable sequences and human constant domain sequences, preferably human gamma 1, gamma 4 or mutated forms thereof. These antibodies possess desirable therapeutic properties including low antigenicity, reduced (or absent) T cell depleting activity, good affinity to human CD4 and enhanced stability (in vivo half-life).

Abstract: The present invention relates to the identification of macaque antibodies to human B7.1 and B7.2 by screening of phage display libraries or monkey heterohybridomas obtained using B lymphocytes from B7.1 and/or B7.2 immunized monkeys. More specifically, the invention provides four monkey monoclonal antibodies 7B6, 16C10, 7C10 and 20C9 which inhibit the B7:CD28 pathway and thereby function as effective immunosuppressants. The invention further provides the complete DNA and amino acid sequences of the light and heavy chain of three primatized antibodies derived from those monkey monoclonal antibodies which bind B7.1 and possibly B7.2, primatized 7C10, primatized 7B6 and primatized 16C10. These primatized and monkey antibodies may be used as specific immunosuppressants, e.g., for the treatment of autoimmune diseases and to prevent organ transplant rejection.

Abstract: A method for achieving site specific integration of a desired DNA at a target site in a mammalian cell via homologous recombination is described. This method provides for the reproducible selection of cell lines wherein a desired DNA is integrated at a predetermined transcriptionally active site previously marked with a marker plasmid. The method is particularly suitable for the production of mammalian cell lines which secrete mammalian proteins at high levels, in particular immunoglobulins. Novel vectors and vector combinations for use in the subject cloning method are also provided.

Abstract: A highly efficient method for generating human antibodies in particular which are specific to be RSV fusion protein which combines in vitro priming of human spleen cells and antigen boosting in SCID mice is taught. This method provides for very high human antibody titers which are predominantly of the IgG isotype which contain antibodies of high specificity and affinity to desired antigens. This method is well suited for generating human monoclonal antibodies for therapeutic and diagnostic applications as well as for rescue of human cells for generation of combinational human antibody gene libraries. Two human monoclonal antibodies, RF-1 and RF-2 which each possess an affinity for RSV F-protein .ltoreq.2.times.10.sup.-9 Molar are taught as well as their corresponding amino acid and DNA sequences. These antibodies are to be used therapeutically and prophylactically for treating or preventing RSV infection, as well as for diagnosis of RSV in analytes.
