摘要:
A compsn. is new, and comprises an antigen (I), except an albumin, mixed with an antigen formulation (II) consisting of: a stabilising detergent; a micelle-forming agent; and a biodegradable and biocompatible oil. (II) is a stable oil-in-water emulsion. Also new is a method for inducing a cytotoxic T-lymphocyte response in a human or animal comprising administering (I) and (II), (II) lacking an immunostimulating peptide component. (I) may be antigenic portions of HIV gp120, malaria antigens, CS protein and Sprorozoite surface protein, influenza antigens, carcinoma P21, etc. (I) also may not include a B-cell lymphoma anitgen.
摘要:
The present invention concerns treatment of autoimmune diseases with the combination of an immunoregulatory antibody, e.g. and anti-B7.1 or anti-B7.2 or anti-CD40L antibody and at least one B cell antibody, such as CD19, CD20, CD22, CD23, or CD37, wherein such antibodies may be administered separately, or in combination, and in either, over prolonged periods of time.
摘要:
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.
摘要:
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.
摘要:
The present invention provides a synergistic composition and methods for treating neoplastic or cancerous growths as well as for treating such patients in order to restore or boost hematopoiesis. The present invention comprises administration of the combination of a cytotoxic T-lymphocyte inducing composition and at least one agent which is capable of neutralizing or down regulating the activity of tumor secreted immunosuppressive factors, separately or in combination.
摘要:
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 signalling. These antibodies may be used as specific immunosuppressants, e.g., for the treatment of autoimmune diseases and to prevent organ transplant rejection.
摘要:
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 for 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 « 2x10-9 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.
摘要:
Disclosed herein are therapeutic treatment protocols designed for the treatment of B cell lymphoma. These protocols are based upon therapeutic strategies which include the use of administration of immunologically active mouse/human chimeric anti-CD20 antibodies, radiolabeled anti-CD20 antibodies, and cooperative strategies comprising the use of chimeric anti-CD20 antibodies and radiolabeled anti-CD20 antibodies.
摘要:
A novel method is disclosed for selecting antibody reagents for vaccine formulations that are capable of inducing group-neutralizing anti-HIV antibody responses in humans. Also disclosed are anti-idiotype antibodies and hybridoma cell lines capable of producing such antibodies. Further, anti-idiotype antibody-based vaccines and formulations thereof are disclosed. The methods, antibodies, hybridomas and vaccine formulations of the present invention may be useful in the treatment and prevention of HIV infection.
