Patent number: 7491393Abstract: 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.Type: GrantFiled: August 17, 2007Date of Patent: February 17, 2009Assignee: Biogen Idec Inc.Inventors: Darrell R. Anderson, Nabil Hanna, Peter Brams

Patent number: 7482003Abstract: The present invention disclosed recombinant anti-VLA-4 antibody molecules, including humanized recombinant anti-VLA-4 antibody molecules. These antibodies are useful in the treatment of specific and non-specific inflammation, including asthma and inflammatory bowel disease. In addition, the humanized recombinant anti-VLA-4 antibodies disclosed can be useful in methods of diagnosing and localizing sites of inflammation.Type: GrantFiled: November 29, 2006Date of Patent: January 27, 2009Assignee: Biogen Idec MA Inc.Inventors: Roy R. Lobb, Frank J. Carr, Philip R. Tempest

Patent number: 7476385Abstract: Methods of suppressing a humoral immune response to a thymus-dependent (TD) antigen are disclosed. The methods involve administering to a subject a TD antigen with an antagonist of a molecule which mediates contact-dependent helper effector functions. In a preferred embodiment, the antagonist is an antagonist of gp39. Primary and secondary humoral immune responses can be suppressed and suppression is prolonged.Type: GrantFiled: January 4, 2005Date of Patent: January 13, 2009Assignee: Trustees of Darthmouth CollegeInventors: Randolph J. Noelle, Teresa M. Foy

Patent number: 7465547Abstract: The present invention provides an antibody prepared using a peptide as an antigen, the peptide having 8 to 30 amino acid residues selected from an amino acid sequence at positions 1 to 68 of human high-molecular-weight CD14, or an antibody that binds to a peptide having a specific amino acid sequence at a position among the positions 1 to 68. An assay kit for human low-molecular-weight CD14 using the antibody and an assay method of the present invention, preferably a sandwich method, are able to quantitatively or qualitatively determine human low-molecular-weight CD14 with high sensitivity and specificity in a simple manner, so that they are useful for the diagnosis of a patient suffering from sepsis.Type: GrantFiled: November 12, 2003Date of Patent: December 16, 2008Assignee: Mochida Pharmaceutical Co., Ltd.Inventors: Shoji Furusako, Kamon Shirakawa

Patent number: 7465464Abstract: Isolated mammalian nucleic acid molecules encoding receptor protein tyrosine kinases expressed in primitive hematopoietic cells and not expressed in mature hematopoietic cells are provided. Also included are the receptors encoded by such nucleic acid molecules; the nucleic acid molecules encoding receptor protein tyrosine kinases having the sequences shown in FIG. 1a (murine flk-2), FIG. 1b (human flk-2) and FIG. 2 (murine flk-1); the receptor protein tyrosine kinases having the amino acid sequences shown in FIG. 1a, FIG. 1b and FIG. 2; ligands for the receptors; nucleic acid sequences that encode the ligands; and methods of stimulating the proliferation and/or differentiation of primitive mammalian hematopoietic stem cells comprising contacting the stem cells with a ligand that binds to a receptor protein tyrosine kinase expressed in primitive mammalian hematopoietic cells and not expressed in mature hematopoietic cells.Type: GrantFiled: January 5, 2005Date of Patent: December 16, 2008Assignee: Trustees of Princeton UniversityInventor: Ihor R.

Patent number: 7462696Abstract: The invention is composed of monoclonal human MN antibodies or MN antibody fragments that target the GEEDLP (SEQ ID NO: 118) repeat within the proteoglycan domain. The proteoglycan domain of the MN cell surface protein contains four of these identical GEEDLP (SEQ ID NO: 118) repeats. Binding to the desired epitope is verified by competition ELISA, where ELISA signal can be attenuated by co-incubation with a peptide containing this repeat (PGEEDLPGEEDLP (SEQ ID NO: 119)). This inhibition of binding can also be verified using Biacore assays, where binding of desired antibodies to immobilized MN or proteoglycan peptides can be inhibited by the peptide repeat. In addition to binding to the peptide repeat, human anti-MN antibodies can inhibit the cell adhesion of CGL-1 cells to MN coated plastic plates. Human anti-MN antibodies have been used to diagnose and quantify MN expression in cancer cells and tumors using FACS and immunohistochemical methods.Type: GrantFiled: October 18, 2002Date of Patent: December 9, 2008Assignee: Bayer Pharmaceutical CorporationInventors: Toshihiko Takeuchi, Nathalie Dubois-Stringfellow, John E.

Patent number: 7449183Abstract: Endothelialization of vascular surfaces. According to one aspect, the invention involves a technique for re-endothelializing an artery whose endothelial layer has been damaged by balloon angioplasty. The technique comprises, in one embodiment, introducing into the bloodstream of a patient, prior to performing the angioplasty, a quantity of a bispecific antibody, the bispecific antibody having a first antigen binding site directed against a surface marker common to both endothelial progenitor cells (EPCs) and endothelial cells (ECs) and having a second antigen binding site directed against a subendothelial epitope. The bispecific antibody is introduced in a quantity sufficient to bind a substantial percentage of circulating EPCs and circulating ECs. In this manner, once the angioplasty has been performed and the target epitopes on the subendothelium have been exposed, the bispecific antibodies that have already become bound to the circulating EPCs and ECs also then bind to the subendothelium.Type: GrantFiled: January 18, 2007Date of Patent: November 11, 2008Inventors: A. Mark Colb, Herman K. Gold
