The programmed cells are multipurpose tools.

Prologue: Wolves of Chernobyl

In the Chernobyl nuclear radiation fall-out areas, live animals with higher resistance to radioactive exposure than normal animals. The reason for that is in the DNA enrichment. The radioactive exposure kills others than animals that can resist the exposure. The question is, what is the point that makes the resistance? 

In some models, the thing that makes the animal resistant to radioactive exposure is the immune system. The sensitive immune system can search for and destroy mutated cells more effectively and faster than in the animal's body, which lives outside the fall-out area. 

The biorobots can make it possible to create the ultimate treatment against radioactive exposure. Those systems require the fresh and non-damaged DNA. Nanotechnology can create that DNA from the digital image. 

The system must only create macrophage-style cells that can destroy damaged DNA. And take it out from the cells. And then replace that damaged DNA from the cell's nucleus. The biorobot must also remove damaged mitochondria and then inject new mitochondria into the cells. This kind of biorobot can produce mitochondria and inject them into cells. Another biorobot or engineered bacteria can remove damaged mitochondria from those cells. This technology brings immortality closer than ever before. 

"Scientists have reprogrammed immune cells to selectively defend the body, preventing attacks on healthy tissue while still allowing natural defenses. This breakthrough could replace broad immunosuppression, offering safer treatments for autoimmune diseases, transplants, and even cancer therapy.

Reprogrammed cells stopped the autoimmune attack. 

Researchers crack the DNA code of human brains and reprogram immune cells to stop autoimmune attacks. Those two things would be interesting and revolutionary alone. But, the ability to program cells makes it possible to adjust the growth of the human brain. That means that in the future, researchers can adjust how the persons focus their intelligence. That allows the creation of people with certain highlighted abilities, like mathematical, geometrical, or linguistic gifts. 

The ability to program immune cells can make them stop autoimmune diseases. But those cells can also used to remove things like cancer cells or unwanted tissues. The programmed immune cells can also clean tissues in cases of injuries or remove chemical exposure. In the case of radioactive exposure, the programmed immune cells can search and destroy damaged and dying cells.  And in the most interesting visions, the ability to adjust and program immune cells can be used to clean blood vessels and remove plaque from the human brain. 

But, the ability to program neurons is a thing that can be used to create systems that can be more than computers. Biohybrid microchips are microchips that have two layers. Living neurons interact with microchips. And that makes them more intelligent than regular microchips. The ability to program neurons makes it possible to create new methods to fix large-scale neural damage.  The ability to program cloned neurons is the thing that gives new hope to people who are injured.
