摘要:
The invention concerns chimeric monoclonal antibodies, humanized or human produced in selected cell lines, said antibodies exhibiting high affinity for the CD16 receptor of effector cells of the immune system and hence capable of inducing high ADCC, but also the property of inducing cytokine and interleukin secretion, in particular IFNγ, which can enhance the ADCC activity of effector cells and hence be used for treating cancers and infections by pathogenic agents.
摘要:
The present invention relates to the use of an antibodies composition, the fucose content of which is less than 65%, for indicating apoptosis in vitro.
摘要:
The invention relates to an anti-idiotypical antibody targeting an antibody inhibiting the human factor VIII, said inhibiting antibody targeting the C2 region of the human factor VIII, the variable region of each of the light chains thereof being encoded by a sequence of nucleic acids of which at least 70% is identical to the murine sequence of nucleic acids SEQ ID NO: 1, and the variable region of each of the heavy chains thereof being encoded by a sequence of nucleic acids of which at least 70% is identical to the murine sequence of nucleic acids SEQ ID NO: 2, the constant regions of the light chains and the heavy chains being constant regions from a non-murine species. The invention also relates to the use of said antibody for activating the FcγRIII receptors of cytotoxic immune cells, and to the production of a medicament especially for the treatment of haemophilia A.

摘要:
The invention relates to the use of optimised human or humanised chimeric monoclonal antibodies which are produced cell lines, said antibodies having a strong affinity for receptor CD16 of the effector cells of the immune system and being able to induce the secretion of cytokines and interleukins, in particular 1′ IFN? or 1′ IL2, for the treatment of pathologies for which the target cells only express a low antigenic density and in which the effector cells can only be recruited in small quantities.
摘要:
The invention concerns a method for obtaining and selecting monoclonal antibodies by an ADDC-type test, said antibodies capable of activating type III Fcγ receptors and having a particular glycan structure. The inventive anti-D antibodies can be used for preventing Rhesus isoimmunisation in Rh negative persons, in particular for haemolytic disease in a new-born baby or for uses such as idiopathic thrombocytopenic purpura (ITP).

摘要:
The invention relates to a method of measuring the activation of an effector cell belonging to the immune system, which may or may not be transformed, using a monoclonal (AcMo) or polyclonal antibody. The invention is characterised in that it consists in: bringing into contact (i) CD16 receptor-expressing cells in a reaction medium in the presence of the antibody and (ii) the antigen of said antibody, and measuring the quantity of at least one cytokine produced by the CD16 receptor-expressing cell. The invention also relates to the selection of an antibody capable of inducing the expression of cytokines and interleukins, such as IFN? or IL2 which are intended for the treatment of autoimmune and inflammatory diseases, cancers and infections by pathogens.
