摘要:
The present invention provides a method for inhibiting an immune response and a method for inhibiting rejection of transplanted tissues. This method comprises preventing an endogenous molecule on a cell selected from the group consisting of gp39 and CD40 antigens from binding its endogenous ligand and preventing an endogenous molecule on a cell selected from the group consisting of CTLA4, CD28, and B7 antigens from binding its endogenous ligand. The prevention of such molecules from binding their ligand thereby blocks two independent signal pathways and inhibits the immune response resulting in transplanted tissue rejection.
摘要:
The present invention relates to a counter-receptor, termed CD40CR, for the CD40 B-cell antigen, and to soluble ligands for this receptor, including fusion molecules comprising at least a portion of CD40 protein. It is based, at least in part, on the discovery that a soluble CD40/immunoglobulin fusion protein was able to inhibit helper T-cell mediated B-cell activation by binding to a novel 39 kD protein receptor on helper T-cell membranes. The present invention provides for a substantially purified CD40CR receptor; for soluble ligands of CD40CR, including antibodies as well as fusion molecules comprising at least a portion of CD40 protein; and for methods of controlling B-cell activation which may be especially useful in the treatment of allergy or autoimmune disease.
摘要:
A method for the treatment of T cell mediated disorders is described. The method involves administering to a subject a therapeutically effective amount of an anti-human CD40 antibody. Disease states suitable for treatment with this method include graft versus host disease and transplant rejection and auto immune disease such as type I diabetes, psoriasis, multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus, and myesthenia gravis.
摘要:
A new polypeptide from the scavenger receptor cysteine-rich family, termed Sp.alpha. herein, as well as polynucleotides encoding Sp.alpha. and methods of recombinantly producing the same, are disclosed. In addition, antibodies reactive with Sp.alpha. are provided, as are methods of using antibodies that bind to Sp.alpha. for modulating the interaction between Sp.alpha. and its receptor. Immunoassay kits containing the anti-Sp.alpha. antibodies are also provided.

摘要:
Novel articifial proteoglycans containing a GAG assembly site and a control sequence required for assembly, method for enhancing the biological activity of a glycosaminoglycan binding protein using artificial proteoglycans, DNA constructs of artificial proteoglycans. The artificial proteoglycans of the present invention are useful for preparations of adjuvants for vaccination, for targeting of chemokines to non-immunogenic tumor cells to enhance cellular anti-tumor response, for preparations designed to help promote wound healing, and for treatment of immunological disorders,including rheumatoid arthritis, asthma, chronic obstructive pulmonary disorder, Lupus, inflammatory bowel disease, psoriasis, osteoarthritis, and HIV infection.
摘要:
The instant invention discloses the unexpected result that two anti-4-1BB monoclonal antibodies can inhibit both primary and secondary humoral responses to at least T-cell dependent antigens in vivo. Such antibodies provide a novel approach to immunosuppression and cancer therapy in vivo.
