日本东京理科大学最近成功地用转基因水稻生产出预防乙肝病毒的球蛋白,为用廉价而安全的手段生产预防肝炎药物提供新思路。以前,有效地预防乙肝的免疫球蛋白是使用受过感染的人的血液精制而成的,价格昂贵。研究人员把制造乙型肝炎病毒的抗体基因植入水稻细胞中并加以栽培后,成功地从水稻叶中提取出了这种抗体,研究结果表明,这种抗体对病毒产生了抑制作用。 Tokyo University of Science and Technology in Japan recently successfully used genetically modified rice to produce hepatitis B virus globulin, which will provide new ideas for cheap and safe means to prevent hepatitis drugs. Previously, the immunoglobulin that is effective in preventing hepatitis B is purified from the blood of an infected person and is expensive. The researchers successfully isolated the hepatitis B virus antibody gene from rice leaves and cultivated it, and showed that the antibody produced an inhibitory effect on the virus.
