Methods for preventing or treating an antibody-mediated disease in a patient are presented, the methods comprising administration of a monoclonal antibody capable of binding to a human CD40 antigen located on the surface of a human B cell, wherein the binding of the antibody to the CD40 antigen prevents the growth or differentiation of the B cell. Monoclonal antibodies useful in these methods, and epitopes immunoreactive with such monoclonal antibodies are also presented.

Anti-CD40 antibodies capable of blocking B-cell activation

Methods for preventing or treating an IgE-mediated allergic disease in a patient are presented, the methods comprising administration of a monoclonal antibody capable of binding to a human CD40 antigen located on the surface of a human B cell, wherein binding of the antibody to the CD40 antigen prevents the growth or differentiation of the B cell. Monoclonal antibodies useful in these methods, and epitopes immunoreactive with such monoclonal antibodies are also presented.

Method for treating an IgE-mediated disease in a patient using anti-CD40 monoclonal antibodies

Methods for preventing or treating an antibody-mediated diease in a patient are presented, the methods comprising administration of a monoclonal antibody capable of binding to a human CD40 antigen located on the surface of a human B cell, wherein the binding of the antibody to the CD40 antigen prevents the growth or differentiation of the B cell. Monoclonal antibodies useful in these methods, and epitopes immunoreactive with such monoclonal antibodies are also presented.

Methods of blocking B-cell activation using anti-CD40 monoclonal antibodies

CD40 antigen antibody complex

Methods of blocking B cell proliferation using anti-CD40 monoclonal

Described herein are compositions that have prophylactic or therapeutic applications for disease resulting from the production of cytokines, and preferably the cytokine IL-6, wherein the compositions consist of activin like molecules.

Inhibitor of cytokine activity and applications thereof

Methods for causing T cell anergy, treating allograft transplant rejection, treating graft versus host disease, and preventing or treating rheumatoid arthritis are presented, the methods comprising co-administration of a molecule that binds to the B7 antigen and an immunosuppressive agent.

Methods of blocking T-cell activation using anti-B7 monoclonal antibodies

Anti-B7-1 antibodies or other B7-1 ligands may be used to prevent or treat a T-cell-mediated immune system disease in a patient or to induce antigen-specific tolerance. The anti-B7-1 antibodies may be used to cause T cell anergy, treat allograft transplant rejection, treat graft versus host disease, and prevent or treat rheumatoid arthritis. An immunosuppressive agent is co-administered with the antibody.

Methods and materials for the induction of T cell anergy

Anti-CD40 monoclonal antibodies capable of blocking B-cell activation

The present invention relates to a method of generating antibodies directed against cell surface antigens. The method uses as immunogen recombinant insect cells into which have been transfected coding regions for a molecule containing a cell surface antigen. Host animals are immunized with these transfected insect cells to generate antibodies directed against the cell surface antigen. Antibody-producing cells from the host animal are used to generate monoclonal antibody-producing hybridoma cells. Sera and hybridoma supernatants can be tested for the presence of antibodies against the surface antigen, using the transfected cells in a screening assay.
