Abstract: OBJECTIVE: The purpose of this study was to evaluate the long-term expression of a transgene and subsequent immune response after the injection of lentiviral vectors in a fetal rats. STUDY DESIGN: Fetal rats were injected in the liver, peritoneal cavity, or lung at E19 (term, E21) with a lentiviral vector expressing enhanced green fluorescent protein and luciferase. Controls received saline solution. After birth, full body bioluminescence was done at weeks 1, 4, 10, and 30 of life; seroconversion for the transgene was assessed. RESULTS: All surviving fetuses that had been injected in the liver (8/9 fetuses), peritoneum (3/3 fetuses), or lung (9/10 fetuses) showed a signal on bioluminescence imaging scan up to 30 weeks. None of the survivors displayed seroconversion against the transgene. CONCLUSION: In the rat model, the administration of lentiviral vectors into the fetal lung and liver resulted in long-term transgene expression without detectable humoral immune response.
