Patent
Innate Pharma | Date: 2015-03-23

The present invention relates to agents and methods that are capable of augmenting NK-mediated killing of target cells by reducing inhibitory KIR signalling without reducing the binding of KIR to HLA-C. As described herein, transduction of negative signaling via KIR, upon binding of KIR to its HLA class I ligand, can involve a ligand-binding induced, conformational reorientation of the KIR molecules allowing interactions to form between adjacent KIRs in specific domains, leading to accelerated clustering. Methods and agents such as monoclonal antibodies for reducing KIR-mediated inhibition of NK cell cytotoxicity without reducing or blocking HLA-binding by, e.g., reducing or blocking dimerization of KIR, are provided.

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.

Compositions and methods for regulating an immune response in a subject are described. More particularly, described are human antibodies that regulate the activity of NK cells and allow a potentiation of NK cell cytotoxicity in mammalian subjects, and antibodies having antigen-binding properties similar to those of human monoclonal antibody 1-7F9 or 1-4F1. Described also are also fragments and derivatives of such antibodies, as well as pharmaceutical compositions comprising the same and their uses, particularly for use in therapy, to increase NK cell activity or cytotoxicity in subjects.


The present invention relates, generally, to methods and compositions for increasing the efficiency of therapeutic antibodies. Their efficiency is enhanced through the increase of the ADCC mechanism. More particularly, the invention relates to the use of a therapeutic antibody in combination with compounds that block an inhibitory receptor or stimulate an activating receptor of an NK cell in order to enhance the efficiency of the treatment with therapeutic antibodies in human subjects.
