    • The invention relates to the coupling or to the genetically fusing of two different proteins: one, which has the property of binding selectively to a target cell, such as an antibody or a ligand for a receptor overexpressed on target cells, and one consisting of a monomorphic MHC class I related protein, such as MIC-A or -B, or ULBP, or CD1d. This conjugate or fusion protein is designed to be localized in vivo on the surface of the target cells such as tumor cells or cells involved in neoangiogenesis. The high density of these monomorphic MHC class I related proteins will activate effector cells such as NK, NKT or other T cells with the objective to kill the targeted cells. The advantage of these MHC class I related molecules is that since they are monomorphic, the same conjugate or fusion protein can be used in every patient. Furthermore, the NK or NKT cells being involved in innate immunity , the reaction will be more rapid than that of acquired immunity and will involve a much higher population than antigen-specific MHC restricted T cells

    • A conjugate comprising an essentially non-toxic peptide T cell antigen, which is capable of forming a complex with MHC class I or II molecules, and a binding partner for a surface receptor on mammalian target cells, whereby a) the binding partner has a high degree of selectivity for said target cells; by binding to substances which are expressed on the surface of said cells; b) the conjugate comprising the binding partner and the T cell antigen is internalized in said cells after binding of the binding partner to its surface receptor on said cells; c) the T cell antigen is processed from the conjugate and expressed on the cell surface in the form of a complex with MHC molecules, whereby said complex is recognized by the T cell receptor, thereby inducing cytotoxicity of T cells for the aforesaid target cells, is useful to induce specific cytotoxicity of T cells in the treatment of cancer autoimmune diseases, diabetes or allergic reactions.
