摘要: Primary human natural killer (NK) cells recognize and subsequently eliminate virus infected cells, tumor or other aberranT-cells. However, cancer are able to develop immune escape mechanisms undermine this control. To overcome obstacle, NK can be genetically modified express chimeric antigen receptors (CARs) in order improve specific recognition of surface markers (e. g. CD19, CD20, ErbB2). After target recognition, intracellular CAR domain signaling (CD3zeta, CD28, 4-1BB, 2B4) lead activation PI3K DNAX proteins (DAP10, DAP12) finally enhanced cytotoxicity, proliferation, and/or IFNgamma release. This mini-review summarizes both the first pre-clinical trials with engineered primary translational implications for “off-the-shelf-immunotherapy” treatment. Signal transduction as well optimization will described, becoming more a focal point interest addition redirected T-cells. Finally, strategies off-target effects discussed future clinical avoid attacking healthy tissues.
