Expression of FMS-like Tyrosine Kinase 3 Ligand by Oncolytic Herpes Simplex Virus Type I Prolongs Survival in Mice Bearing Established Syngeneic Intracranial Malignant Glioma

摘要

BackgroundGlioblastoma is a fatal brain tumor in dire need of effective therapy. Treatments with both oncolytic viruses and immunotherapy have shown preclinical efficacy and clinical promise. We sought to exploit possible synergies between oncolytic herpes simplex virus – type I (oHSV-1) infection of intracranial gliomas and delivery of immune stimulating fms-like tyrosine kinase 3 ligand (Flt3-L) by engineering a herpes vector to express the cytokine.
