In the September 25 2020 issue of the journal Science researchers report on the invention of a sequence of switches made entirely of protein that can perform AND OR and NOT Boolean logical operations, and thus is Turing Complete, they call it Co-LOCKR. And they were able to put this simple computer into a T-Cell antibody, and so they could activate the T-Cell only when specific conditions are met.
Designed protein logic to target cells with precise combinations of surface antigens <https://science.sciencemag.org/content/369/6511/1637> By examining the antigens on the surface of a specific type of cancer cell you can distinguish cancer cells from healthy normal cells, but it's more complex than just looking for one specific antigen. However with Co-LOCKR a T-Cell could be programmed for example, to only attack cells that have antigens W OR X AND NOT both on their surface, AND antigen Y, AND NOT antigen Z. That way the T cell would attack cancerous cells but leave normal healthy cells alone. This is almost starting to sound a little like a simplified version of one of Drexler's Nanomachines.
