The ability to precisely extricate and manipulate fragments of our genome in order to abrogate mutations or turn off overactive genes seems like the fantasy tales written about in science fiction novels and comic books. Yet, at present researchers are becoming ever more successful at accomplishing those seemingly fictional techniques using the genome editing tool known as CRISPR/Cas9.

Now, investigators from the University of California San Francisco (UCSF) have developed a new strategy to precisely modify human T cells using CRISPR/Cas9—implications that could have sweeping impacts on AIDS, cancer, and various other autoimmune disorders.
