Reporting April 2 in the journal Science, a team led by the University of Washington School of Medicine has created artificial proteins that function as molecular logic gates. These tools, like their electronic counterparts, can be used to program the behavior of more complex systems.

The team showed that the new designer proteins can regulate gene expression inside human T-cells. This development may improve the safety and durability of future cell-based therapies.
