Previous studies have demonstrated that a defective recombinant adenovirus can infect a wide range of postmitotic and slowly proliferating cell types such as hepatocytes, myotubes, pneumocytes and intestinal cells (Stratford-Perricaudet et al., Hum. Gene Ther., 1, 241-256, 1990; Quantin et al., Proc. Natl. Acad. Sci. USA, 89, 2581-2584, 1992; Jaffe et al., Nature Genetics, 1, 372-378, 1992). We have used a defective recombinant adenovirus, Ad.RSV beta gal, containing the Escherichia coli beta-galactosidase gene targeted to the nucleus under the transcriptional control of the Rous sarcoma virus long terminal repeat promoter (Stratford-Perricaudet et al., J. Clin. Invest., 90, 626-630, 1992) to infect non-dividing neural cells in primary culture. We show that 80-100% of neuronal and astroglial cells infected with a viral titre lower than 10(9) p.f.u./ml express beta-galactosidase for at least 1 month without cell damage. These results demonstrate the potential usefulness of recombinant adenovirus infection for the analysis of brain-specific gene regulation and for the transfer of genes into neural cells before their transplantation into the brain.
