    • 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
