摘要

Recombinant replication-deficient Semliki Forest virus (SFV) expressing bacterial ? -galactosidase was injected into the amygdala and striatum of male Wistar rats. Reporter gene expression was detected up to 28 days post-injection. The maximal expression levels were obtained 1-2 days post- injection. In situ hybridization studies demonstrated high expression of LacZ mRNA until day 2, but no signal was detected 4 days post-injection. No significant change in body weight and temperature, exploratory locomotor behavior and forced motor performances were observed after SFV-LacZ injections. The neuronal gene transfer with SFV vectors did not trigger any major cell toxicity.
