Great achievement in the fight against HIV: the virus was eliminated in mice DNA

Great achievement in the fight against HIV: the virus was eliminated in mice DNA - picture 1

New hope in HIV treatment was given by temple University in cooperation with the University of Pittsburgh this Monday. A technique of gene-editing is able to liquidate HIV DNA of mice.
Usually the virus preserves several reservoirs in some cells. ARVT drugs don’t give an opportinity to HIV-virus to be replicated, but they could do nothing with the rescue of these reservoir bodies.
CRISPR/Cas9, better known as molecular scissors makes possible the elimination of HIV-virus in mice DNA no matter on the virus-stage.

CRISPR/Cas9 protein is used for partial remotion of HIV from cell’s DNA. Before the abovementioned researches molecular scissors were used to delete CCR5 in T’cells, also used by HIV-virus, which transfers them immune to HIV. Afterall we have HIV DNA deleted from the cell inself. To see how that technology works in a context of human virus, the scientists need to examine the similar study on primates, whoes virus behaves just closer the the himan’s one.


Possibility of editing genes could be very significant in finding a treatment not only for HIV, but also for cancer. This is a very young science, if we could say so and it needs many more studies, researches, experiments and so on.
