Potential cure for HIV discovered

In a breakthrough that could potentially lead to a cure for HIV infection, scientists have discovered a way to remove the virus from infected cells.

The scientists engineered an enzyme called Tre which attacks the DNA of the HIV virus and removes the virus from the genome of infected cells by recognizing and then recombining the structure of the virus's DNA, according to the study published in Science magazine.

This ability to recognize HIV's DNA might one day help overcome one of the biggest obstacles to finding a cure: the ability of the HIV virus to avoid detection by reverting to a resting state within infected cells which then cease to produce the virus for months or even years.

The enzyme is still far from being ready to use as a treatment, the authors warned, but it offers a glimmer of hope for the more than 40 million people infected worldwide.
