Patent 7838659 was granted and assigned to University of Florida on November, 2010 by the United States Patent and Trademark Office.
Hammerhead ribozymes that target components critical to HSV replication (ICP4, UL20, UL30, and UL54) were synthesized and shown to efficiently cleave target RNA encoding a portion of these components in in vitro assays. Several cloned cell lines stably expressing these ribozymes were established. HSV-mediated plaque formation was dramatically reduced in cells stably transfected with an anti-HSV ribozyme compared to non-transfected cells.
