5 . Researchers have successfully changed the blood type of a donated human lung by treating it with enzymes(酶) marking an important step towards making universal donor organs.

Blood types are largely defined by the presence or absence of certain sugar molecules (分子) called antigens(抗原) on the surface of cells. These can occur not just on the cells of the blood itself, but other tissues. If an antigen isn’t recognized by the body’s immune system, it will mount an attack on these cells. This leads to the rejection of transplanted organs from a donor with a different blood type.

People with the most common blood type, O, lack these antigens on their cells, so their organs can be accepted by people with other blood types. If all donor organs could be made type O, for example, the lungs from someone with blood type A, this could be beneficial.

To try this, Cypel and his team used a pair of enzymes in the human stomach to digest sugars. They found the enzymes could remove 97 percent of type A antigens in the lungs from a type A donor in 4 hours, which meant the cells had been effectively changed to blood type O.

After this treatment, the altered lungs were kept alive using a system known as ex-vivo lung perfusion (离体肺灌注), which supplies organs with nutritious fluid so they are ready for transplantation. To simulate a transplant, Cypel’s team added type O blood, which contains antibodies that would attack type A antigens, to the fluid supplying the lungs. The treated lungs had minimal antibody damage compared with untreated lungs.

Although cells rid of antigens tend to produce new ones over time, Cypel hopes the lack of antigens would last long enough for the body to get through the dangerous first few days and weeks after a transplant. The team now intends to test the procedure in animals. The study only looked at the effects of a simulated transplantation over the short term, which isn’t enough to assess whether the resurfaced antigens could eventually have a negative effect.

A．The blood type was temporarily changed.

B．Signs of severe rejection happened to them.

C．There was no effective way to keep them alive.

D．The enzymes were of little use in the treatment.
