Abstract

A novel and stable attenuated poliovirus, which replicates in neuroblastoma cells, is produced by engineering an indigenous replication element (cre), into the 5′ non-translated genomic region and inactivating the native cre element located in the coding region of 2C (mono-crePV). The stably attenuated poliovirus replicates in a neuroblastoma model (Neuro-2aCD155 tumors) expressing CD155, the poliovirus receptor, and is effective for oncolytic treatment and cure of solid tumors, such as neuroblastoma.
