    • 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.

    • Methods for inducing antigen-specific T cell tolerance are disclosed. The methods involve contacting a T cell with: 1) a cell which presents antigen to the T cell, wherein a ligand on the cell interacts with a receptor on the surface of the T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor on the surface of the T cell which inhibits interaction of the ligand on the antigen presenting cell with the receptor on the T cell. In a preferred embodiment, the cell which presents antigen to the T cell is a B cell and the receptor on the surface of the T cell which mediates contact-dependent helper effector function is gp39. Preferably, the antagonist is an anti-gp39 antibody or a soluble gp39 ligand (e.g., soluble CD40). The methods of the invention can be used to induce T cell tolerance to a soluble antigen or to an allogeneic cell. The methods of the invention can also be used to induce tolerance in cases of bone marrow transplantation and other organ transplants and to inhibit graft-versus-host disease.
    • 公开了诱导抗原特异性T细胞耐受性的方法。 所述方法包括使T细胞接触:1)向T细胞呈递抗原的细胞,其中细胞上的配体与介导接触依赖性辅助效应子功能的T细胞表面上的受体相互作用; 和2)T细胞表面上的受体拮抗剂,其抑制抗原呈递细胞上的配体与T细胞上的受体的相互作用。 在优选的实施方案中,向T细胞呈递抗原的细胞是B细胞,介导接触依赖性辅助效应子功能的T细胞表面上的受体是gp39。 优选地,拮抗剂是抗gp39抗体或可溶性gp39配体(例如可溶性CD40)。 本发明的方法可用于诱导对可溶性抗原或同种异体细胞的T细胞耐受性。 本发明的方法还可用于在骨髓移植和其他器官移植的情况下诱导耐受性并抑制移植物抗宿主病。
