Researchers at King's College London in Britain have identified a new gene that can prevent the spread of HIV virus once it enters the body.
The researchers conducted a number of experiments on human cells and found that the gene, known as MX2, can stop the progression of HIV virus. The researchers introduced the virus on two sets of human cells, where in one set the MX2 gene was 'silenced' while in the other set the gene was switched on.
The researchers found that while the HIV virus replicated and spread in the first set, it was unable to do so in the second set. The study has been published in the journal Nature.
