It is said that the death of pig heart transplant recipients is related to pig virus. How does this research help the field of heart transplantation?

Genetic programming of pig heart is effective.

Although this pig heart transplant is a risky operation, it is still of epoch-making significance. Although the pig heart is suitable for human beings, the human immune system will still reject the pig heart, causing great harm to the human body and even death in serious cases. So this time, the pig's heart was genetically programmed, and the rejection gene in the pig's heart was removed, which made the transplant operation go smoothly. In addition, the transplanter also held a rock activity two weeks ago, which can be said that this technology is very successful.

The virus problem of pig heart needs attention.

Although the effect of pig heart transplantation is very good in the first two weeks, there are still serious problems in the later treatment. Although the phenomenon of immune system rejection is avoided, the virus hidden in pig heart has caused serious harm to human body. Although the virus carried in the pig's heart is not as suitable for human body as the virus in primates, and the virus in the pig is not so harmful to human body in theory, it is also difficult to deal with, so it finally died of virus infection two months after transplantation.

This is very helpful for xenotransplantation technology.

? Because of the gradual progress of human medicine, there have been many breakthroughs in diseases that could not be cured, such as transplanting similar organs instead, but these human organs can only be transplanted after voluntary donation and successful matching, and the number is very small. This case of pig heart transplantation opens a new door for human medicine to treat patients by transplanting animal hearts or organs. Although the result this time is a failure, it is an epoch-making event for human medicine.
