Glioblastoma (GBM) is a deadly primary brain tumor. Current treatment, consisting of surgical removal of the tumor mass followed by chemotherapy and/or radiotherapy, does not significantly prolong survival. Gene therapies for GBM are being developed in clinical trials, for example using adenoviral vectors. While adeno-associated virus (AAV) represents an alternative vector system, limited gene transfer to glioma cells has hampered its use. Here, we evaluated newly emerged variants of AAV capsid for gene delivery to murine glioma. We tested a mutant AAV2 capsid devoid of 3 surface-exposed tyrosine residues, AAV2 (Y444-500-730F), and a "shuffed" capsid (ShH19, containing sequences from several serotypes) that had previously been selected for enhanced glial gene delivery. AAV2 (Y-F) and ShH19 showed improved transduction of murine glioma GL261 cells in vitro by 2- to 6-fold, respectively, over AAV2. While AAV2 gene transfer to GL261 cells in established tumors in brains of syngeneic mice was undetectable, intratumoral injection of AAV2 (Y-F) or ShH19 resulted in local transduction of approximately 10% of tumor cells. In addition, gene transfer to neurons adjacent to the tumor was observed, while microglia were rarely transduced. Use of self-complementary vectors further increased transduction of glioma cells. Together, the data demonstrate the potential for improved AAV-based gene therapy for glioma using recently developed capsid variants.
