Researchers announced on Sunday that some genetically engineered immune cells could find the HIV virus in the body. This could offer a wide way to cure the disease that has been said to be impossible to cure. A study made in the laboratory showed that the T-cells, also called assassin cells, can spot the cells infected by the virus and slow its spread inside the whole body.

Researchers in the United States and Britain said that if the process works inside the body too, this could mean a new way to cure HIV. Angel Varela-Rohena of the University of Pennsylvania, who was part of the study, told Reuters that "billions of these anti-HIV warriors can be generated in two weeks."

A second study, which released an unrelated report, showed that Dutch biotechnology firm Crucell NV’s HIV vaccine could prevent the infection in six monkeys. The monkeys were infected with the SIV version of the virus, so the vaccine would be dangerous for human use. The researchers now work for a human version of the vaccine.

 Dr. Dan Barouch of Beth Israel Deaconess Medical Center and Harvard Medical School in Boston, together with his colleagues stated that there is a real hope for releasing a vaccine that could prevent and cure the mortally disease caused by AIDS virus.

The virus is a real challenge for every researcher as it infects 33 million people all around the world every year. And its infecting process is really hard to be prevented. The virus kills cells in the victim and forces them to turn into viral factories and develop much more virus.
