Successful T cell engineering with gene scissors
(PHYSorg.com Biology)

The idea of genetically modifying a patient`s own immune cells and deploying them against infections and tumors has been around since the 1980s. But to this day modified T cells are still not as effective as natural T cells and have been only been of limited clinical value. Using the new CRISPR-Cas9 gene editing tool, a team at the Technical University of Munich (TUM) has now engineered T cells that are very similar to physiological immune cells.
