Researchers have eliminated HIV from cells in a laboratory, raising hopes of a cure for the virus, which results in the dreaded Acquired Immune Deficiency Syndrome (AIDS).Using a gene-editing tool known as Crispr-Cas , which won the Nobel Prize in 2020, scientists were able to target HIV DNA, removing all traces of the virus from infected cells.Working essentially as scissors, the technology can cut the DNA at certain points, allowing unwanted genes to be deleted, or new genetic material to be introduced into cells.The study authors said their aim was to develop a robust and safe Crispr-Cas regimen, striving for an inclusive HIV cure for all that can inactivate diverse HIV strains across various cellular contexts.The scientists are led by Dr Elena Herrera-Carrillo and part of her team (Yuanling Bao, Zhenghao Yu and Pascal Kroon) at Amsterdam UMC, Netherlands.They said they have developed an efficient attack on the virus in various cells and where it may be hiding.
