The NKG2D receptor: sensing stressed cells. The activating killer cell lectin-like receptor NKG2D plays a key role in the natural killer (NK) cell-mediated lysis of tumours and infected cells.
The invention belongs to the technical field of biology, and relates to a method for differentiating human induced pluripotent stem cells into natural killer cells. The method comprises the following steps of 1, differentiating the human induced pluripotent stem cells to form endothelial progenitor cells with expression of KDR+CD73+; 2, performing endothelial-blood conversion on the endothelial progenitor cells with the expression of KDR+CD73+ to form NK progenitor cells with the expression of CD34-CD45+; and 3, further differentiating the NK progenitor cells into NK cells with expression of CD56+CD3-. The NK cells produced by the scheme provided by the invention highly express NKG2D receptors, and have stronger cytokinesecretion ability and tumor killing ability.
The present application relates to the field of immunotherapy, more particularly to the manufacture of cells for adoptive cell therapy. Provided herein are methods to prevent and / or reduce fratricideduring manufacturing of such cells, particularly of cells expressing a chimeric NKG2D receptor. Also provided are cells and compositions comprising cells in which fratricide is prevented and / or reduced.
