    • Artificial systems for the production of infectious human papillomavirus allow development of diagnostic and therapeutic strategies based on replication and infectivity studies for diseases caused by these viruses. The artificial introduction of papillomavirus genomic DNA into an epithelial cell line. In particular, HPV type 18 genomic DNA is transfected into primary keratinocytes. Transfection is followed by clonal expansion of the transfected cells, and induction of epithelial stratification and differentiation in organotypic cultures resulting in the synthesis of virions. Virus particles synthesized were approximately 50 nanometers in diameter as observed by electron microscopy. In particular HPV18 virions produced by the system and purified by an isopycnic gradient were capable of infecting keratinocytes.
    • 用于生产感染性人乳头瘤病毒的人造系统允许基于由这些病毒引起的疾病的复制和感染性研究开发诊断和治疗策略。 将乳头瘤病毒基因组DNA人工引入上皮细胞系。 特别地,将HPV 18型基因组DNA转染入原代角质形成细胞。 转染之后是转染的细胞的克隆扩增,以及在器官型培养物中的上皮分层和分化的诱导,导致病毒粒子的合成。 合成的病毒颗粒直径约为50纳米,通过电子显微镜观察。 特别是由系统产生并通过等摩尔梯度纯化的HPV18病毒体能够感染角化细胞。
