Universal killer T-cell
Abstract
The present invention relates to a modified natural killer (NK) cell and its use in personalised medicine. The modified NK cells of the present invention are non-immunogenic, meaning that they are able to be administered to any recipient subject without being rejected by the host immune system (they are “universal”). In a first embodiment the non-immunogenic NK cells are modified to express CD3 to allow a T-cell Receptor (TcR) to be expressed. In a further embodiment the non-immunogenic NK cells are further modified to express a TcR together with the CD3 co-receptor. Co-expression of CD3 with a specific TcR results in the modified NK cells showing antigen-specific cytotoxicity towards target cells. Universal NK cells can thus be targeted against specific antigens, and may thus be used in personalised medicine, particularly in the field of oncology.
