American researchers have developed a technique that may become an important tool in fighting AIDS virus from attacking its target-cells in the body's defense system.When AIDS virus enters the blood,it searches for blood cells called T4 lymphocytes .The virus connects to the outside of T4 lymphocytes.Then it forces its way inside.There it directs the cells' genetic material to produce copies of the AIDS virus.This is how AIDS spreads. Researchers think they may be able to stop AIDS from connecting to T4 ceils.When AIDS virus finds a T4 cell,it actually connects to a part of the cell called CD4 protein. Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood.This way the AIDS virus will connect to cloned protein instead of the real ones.Scientists use genetic engineering methods to make the clones.Normally a CD4 protein remains on the T4 cell at all times;the AIDS virus must go to it. In a new technique,however,the cloned CD4 protein is not connected to a cell.It floats freely,so a lot more can be put into the blood to keep the AIDS virus away from real CD4 protein on T4 cells.One report says the.AIDS virus connects to cloned protein just as effectively as it connects to real protein.That report was based on tests with blood cells grown in labs.The technique is just now beginning to be tested in animals.If successful,it may be tested in humans within a year. Which of the following statements is NOT true?
The new technique has been tested in labs. The new technique is being tested in animals. The new technique may be tested in humans. The new technique is now under clinic test.
