Scientists remove HIV-1 from genome of human immune cells
Using the CRISPR/Cas9 gene editing method, scientists found editing HIV out of DNA prevented reinfection by other, unedited cells. By Stephen Feller While many patients benefits greatly from antiretroviral drugs, once they are stopped, HIV in T-cells start replicating and increasing viral load again. Scientists say this could be preventable by editing patients' DNA, based on a recent study.

Using the CRISPR/Cas9 gene editing technique, scientists at Temple University eliminated HIV-1 DNA from T cell genomes in lab experiments, and prevented reinfection after the cells were re-exposed to the virus, they report in a study published in Nature: Scientific Reports .
