Temple scientists find cancer-causing virus in the brain, potential connection to epilepsy
Date:1/24/2013

(Philadelphia, PA) - Researchers at Shriner's Hospital Pediatric Research Center at the Temple University School of Medicine, and the University of Pennsylvania have evidence linking the human papillomavirus 16 (HPV16) the most common cause of cervical cancer to a common form of childhood epilepsy. They have shown for the first time that HPV16 may be present in the human brain, and found that when they added a viral protein to the brains of fetal mice, the mice all demonstrated the same developmental problems in the cerebral cortex associated with this type of epilepsy, called focal cortical dysplasia type IIB (FCDIIB). The findings suggest that the virus could play a role in the development of epilepsy.

The results also mean that doctors may have to re-think their approach to treating this type of epilepsy, and perhaps consider other therapeutic options related to HPV, an infectious disease.

"This is a novel mechanism, and it fills a gap in our understanding about the development of congenital brain malformations," said Peter Crino, MD, PhD, Professor of Neurology at Temple University School of Medicine, and a member of Shriner's Hospital Pediatric Research Center, and the senior author of a recent report in the Annals of Neurology.

"If our data are correct, future treatment of cortical dysplasia could include targeted therapy against HPV16 infection, with the goal of halting seizures. Identifying an infectious agent as part of the pathogenesis of brain malformations could open up an array of new therapeutic approaches against various forms of epilepsy."

FCDIIB is a developmental malformation in the cerebral cortex, the area of the brain that plays key roles in thought, perception and memory. It is a common cause of both pediatric and adult epilepsy especially difficult-to-treat forms of epilepsy and it is thought to occur in the womb during early brain development. The condition is characterized by a disorga
