Abstract: The present invention relates to methods of treating immune disorders, particularly autoimmune or inflammatory disorders, and methods of producing antibodies and other compounds for use in therapeutic strategies for treating such disorders. Generally, the present methods involve the use of antibodies or other compounds that prevent the stimulation of NKG2A receptors on NK cells, leading to the lysis of dendritic cells that contribute to the pathology of the disorders.

Abstract: The present invention relates to the identification of 4Ig-B7-H3 protein as a tumor associated molecule that imparts protection from NK cell-mediated lysis via a 4Ig-B7-H3 receptor on NK cells. The invention provides compounds that interfere with interactions between the 4Ig-B7-H3 protein and its receptor that can be used to potentiate NK cell cytotoxicity. Also provided are compounds that bind 4Ig-B7-H3-expressing cells so as to inhibit or eliminate them. The compounds are particularly useful in the treatment of tumors, inflammatory conditions, infections and transplantation. Also provided are methods for diagnosing disease by detecting a 4Ig-B7-H3 protein.

Abstract: The invention relates to a novel compound termed NKp30 that is selectively expressed by all mature NK cells and that is involved in human natural cytoxicity as an activatory receptor, to new antibodies that bind to the NKp30 structure, and to the pharmaceutical and medicinal uses thereof.

Abstract: The present invention relates to methods of treating proliferative disorders, particularly immunoproliferative and autoimmune disorders, and methods of producing antibodies which bind NK cell receptors for use in therapeutic strategies for treating such disorders, particularly to deplete cells involved in the immunoproliferative pathology.

Abstract: The invention relates to polypeptides having a triggering NK activity and an amino acid sequence that is at least 80% identical over its entire length to the polypeptide having SEQ ID NO: 1, and any immunogenic fragments thereof, as well as to the polyclonal and monoclonal antibodies directed against said polypeptides, and immuno-reactive fragments thereof. Application for detecting NK cells in a sample, for their removal from a sample or for enrichment of NK cells, and for NK cell natural cytotoxicity regulation.
