Abstract: The present application relates to methods and compositions employing an antibody that inhibits activation of the complement system and can be used to prevent or treat a pulmonary disease or condition.

Abstract: Anti-CD40 antibodies are formulated as lyophilizate or liquid formulation. The lyophilizates can be reconstituted to give a solution with a high concentration of the antibody active ingredient for delivery to a patient without high levels of antibody aggregation. The lyophilizate can be reconstituted with an aqueous reconstituent to provide an aqueous composition in which the antibody has a concentration of at least 50 mg/ml. The lyophilizate or aqueous pharmaceutical composition may include one or more of a sugar, a buffering agent, a surfactant, and/or a free amino acid.

Abstract: Anti-human CD40L antibodies engineered to lack the ability to activate platelets and methods for treating patients having a CD40L-associated disease.

Abstract: The present disclosure relates to antibodies and polynucleotides encoding the same, which may be used to prevent, control, or reduce the activity of the complement pathway. In addition, the disclosure is directed to compositions and methods for diagnosing and treating diseases mediated by or involving complement Factor Bb. Specifically, the disclosure is related to anti-complement Factor Bb antibodies.

Abstract: The present invention includes compositions and methods for the expression, secretion and use of novel compositions for use as, e.g., vaccine and antigen delivery vectors, to delivery antigens to antigen presenting cells.

Abstract: This disclosure relates to specific binding agents, such as isolated recombinant monoclonal antibodies, that bind Glycoprotein Ib alpha (GPIba). More specifically, the disclosure relates to methods of preventing platelet ectodomain shedding, preventing platelet clearance and degradation, maintaining and increasing platelet blood serum levels for in vitro or in vivo applications. In some embodiments, the disclosure relates to the production, diagnostic use, and therapeutic use of monoclonal and polyclonal antibodies, and the antigen-binding fragments thereof, which specifically bind GPIba. Aspects of the disclosure also relate to hybridomas or other cell lines expressing such antibodies for specific binding agent. Compositions and methods for inhibiting shedding, clearance, or degradation, or treating diseases associated with GPIba ectodomain shedding are also described.

Abstract: The invention provides an antibody or fragment thereof that specifically binds to human endothelial vascular cell adhesion molecule-1 (VCAM-1), wherein the antibody or fragment thereof binds to the extracellular domain of VCAM-1, and wherein the antibody or fragment thereof binds to VCAM-1 when expressed on endothelial cells, wherein the antibody or fragment thereof is a human or humanized antibody, or fragment thereof.

Abstract: Immunoglobulin chains or antibodies having light or heavy chain complementarity determining regions of antibodies that bind to P-Selectin Glycoprotein Ligand-1. Also disclosed are methods of inducing death of an activated T-cell and of modulating a T cell-mediated immune response in a subject.

Abstract: The present disclosure provides novel anti-CD40 antibodies, compositions including the new antibodies, nucleic acids encoding the antibodies, and methods of making and using the same.

Abstract: An objective of the invention is to provide anti-C5 antibodies and methods of using the same. The invention provides anti-C5 antibodies and methods of using the same. In some embodiments, an isolated anti-C5 antibody of the present invention binds to an epitope within the ? chain of C5 with a higher affinity at neutral pH than at acidic pH. The invention also provides isolated nucleic acids encoding an anti-C5 antibody of the present invention. The invention also provides host cells comprising a nucleic acid of the present invention. The invention also provides a method of producing an antibody comprising culturing a host cell of the present invention so that the antibody is produced. The invention further provides a method of producing an anti-C5 antibody comprising immunizing an animal against a polypeptide which comprises the MG1-MG2 domain of the ? chain of C5. Anti-C5 antibodies of the present invention may be for use as a medicament.

Abstract: The present invention provides Tenascin-3 FnIII domain-based scaffolds that specifically bind to CD40L.
