1·They characterized this retrovirus as the first known human lentivirus based on its morphological, biochemical and immunological properties.
他们此病毒的特点是第一个已知的人类慢病毒根据其形态，生化和免疫学性质。
2·Neurons could survive in the culture for at least 8 weeks, during which the GFP was persistently expressed, indicating the lentivirus could efficiently and stably infect the neurons.
神经细胞至少能存活8周，在此期间GFP能持续表达，说明慢病毒能有效而稳定感染神经细胞。
