Scientists at Temple University made their first successful attempt at eliminating HIV genes from the genomes of mice and rats infected with the virus. They first engineered mice and rats to integrate specific HIV genes with all the other possible cells of their body, before they designed a pair of molecular scissors using a gene-editing technique called CRISPR to cut out those viral genes. The peculiarity of CRISPR is that it precisely snips out the viral genes leaving the animals' own DNA unharmed. Results implies that CRISPR had eliminated HIV from more than 50%of the infected cells of each type. http://time.com/4340722/hiv-removed-using-crispr/
