Progressive multifocal leukoencephalopathy (PML) is a debilitating disease resulting from infection of oligodendrocytes by the JC polyomavirus (JCPyV) and with no anti-viral therapeutic available against JCPyV infection.

In this study, the authors show that the CRISPR/Cas9 system can restrict the JCPyV life cycle in cultured cells with the use of CRISPR/Cas9 to target the noncoding control region and the late gene open reading frame of the JCPyV genome. They found significant inhibition of virus replication and viral protein expression in cells recipient of Cas9 together with JCPyV-specific single-guide RNA delivered prior to or after JCPyV infection.
