Abstract: This invention relates to compositions and methods useful for activating LT-? receptor signaling, which in turn elicits potent anti-proliferative effects on tumor cells. More particularly, this invention relates to lymphotoxin heteromeric complexes formed between lymphotoxin-? and multiple subunits of lymphotoxin-?, which induce cytotoxic effects on tumor cells in the presence of lymphotoxin-? receptor activating agents. Also within the scope of this invention are antibodies directed against the lymphotoxin-? receptor which act as lymphotoxin-? receptor activating agents alone or in combination with other lymphotoxin-? receptor activating agents either in the presence or absence of lymphotoxin-?/? complexes. A screening method for selecting such antibodies is provided. This invention also relates to compositions and methods using cross-linked anti-lymphotoxin-? receptor antibodies either alone or in the presence of other lymphotoxin-? receptor activating agents to potentiate tumor cell cytotoxicity.

Abstract: The present invention relates to the identification of antibodies which are specific to human B7.1 antigen (CD80) and which are capable of inhibiting the binding of B7.1 to a CD28 receptor and which are not capable of inhibiting the binding of B7.1 to a CTLA-4 receptor. Two of these antibodies, 16C10 and 7C10, significantly inhibit the production of IL-2, in spite of the existence of a second activating ligand B7.2 (CD86). Blocking of the primary activation signal between CD28 and B7.1 (CD80) with these antibodies while allowing the unimpaired or coincident interaction of CTLA-4 and B7.1 and/or B7.2 represents a combined antagonistic effect on positive co-stimulation with an agonistic effect on negative signaling. These antibodies or B7.1-binding fragments thereof, may be used for the treatment or prevention of resistance to or rejection of transplanted organs or tissues and/or graft-versus-host diseases.

Abstract: The invention provides Cripto-specific antibodies, or biologically functional fragments thereof, and uses thereof. Antibodies which bind Cripto and inhibit Cripto activity are provided.

Antibodies which bind Cripto and inhibit tumor growth are also provided. Antibodies which bind Cripto, inhibit Cripto activity, and inhibit tumor growth are also provided. The invention also provides methods of using these antibodies in therapeutic, diagnostic, and research applications.

Abstract: The invention provides a method of producing multiple polypeptides, such as antibodies or antibody fragments, in a eukaryotic cell using a single expression vector. The expression vector is engineered to comprise two or more expression cassettes under the control of a single promoter wherein the expression cassettes have splice sites which allow for their alternative splicing and expression as two or more independent gene products at a desired ratio. Use of the vector for the efficient expression of recombinant antibodies in eukaryotic host cells is disclosed as well as the use of such antibodies in diagnostic and therapeutic applications.

Abstract: The present invention relates to a method for enhancing angiogenic activity to promote neovascularization comprising administering to a subject a formulation comprising a synergistically effective amount of a TWEAK agonist and an angiogenic factor.

Abstract: The present invention discloses combined therapies for treating hematologic malignancies, including B cell lymphomas and leukemias or solid non-hematologic tumors, comprising administration of anti-cytokine antibodies or antagonists to inhibit the activity of cytokines which play a role in perpetuating the activation of B cells. The administration of such antibodies and antagonists, particularly anti-IL10 antibodies and antagonists, is particularly useful for avoiding or decreasing the resistance of hematologic malignant cells or solid tumor cells to chemotherapeutic agents and anti-CD20 or anti-CD22 antibodies. The invention also provides combination therapies for solid tumors having B cell involvement comprising the administration of an anti-cytokine antibody and a B cell depleting antibody such as RITUXAN®.

Abstract: The instant invention describes methods of separating or preferentially synthesizing dimers which are linked via at least one interchain disulfide linkage from dimers which are not linked via at least one interchain disulfide linkage from a mixture comprising the two types of polypeptide dimers. These forms can be separated from each other using hydrophobic interaction chromatography. In addition, the invention pertains to connecting peptides that result in the preferential biosynthesis of dimers that are linked via at least one interchain disulfide linkage or that are not linked via at least one interchain disulfide linkage.

Abstract: The present invention relates to a novel process for the preparation of biologically active antibody dimers in a pharmaceutically acceptable composition. The dimers can be composed of two antibody molecules having the same antigen binding specificity and linked through a reducible, disulfide, or a non-reducible thioether, bond (homodimer). Alternatively, the dimers can be composed of two different antibody molecules having binding specificity for two distinct antigens (heterodimer). These dimers are useful for inducing hyper-cross-linking of membrane antigens. The present invention further relates to the use of biologically active antibody dimers for the preferential killing or inhibition of selected cell populations in the treatment of diseases such as cancer and autoimmune disorders.

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.
