概括

反向遗传学使病毒基因组修饰和后代评估成为可能. 由于细胞培养的传播有限,为Calciviridae建立这些系统仍然具有挑战性,这阻碍了常规应用.

科学领域:

病毒学病毒学
分子生物学分子生物学
遗传学是一个遗传学.

背景情况:

反向遗传学涉及修改病毒基因组以研究后代和表型.
重组DNA技术的进步促进了基因隔离,克隆和突变发生.
成功的逆转基因通常依赖于从感染过的"传染性克隆"中拯救传染性病毒.

研究的目的:

审查在建立反向遗传系统的挑战和成功的Caliciviridae.
讨论在生成传染性calicivirus克隆时遇到的陷和延迟.

主要方法:

使用含有全长病毒基因组的传染性克隆.
通过修改病毒基因组传染细胞培养.
评估传染性病毒后代和表型变化的产生.

主要成果:

反向遗传学对于DNA病毒来说很简单,但对于RNA病毒来说具有挑战性.
由于细胞培养的传播不良,很难确定卡利西维里代的逆遗传学.
尽管早期取得了成功,但反向遗传学方法对caliciviruses不是常规的.

结论:

卡利西维里代的逆遗传系统不容易推断到其他家族成员.
很少有报告详细介绍了成功的反向遗传系统对caliciviruses.
克服细胞培养适应方面的挑战对于推进calicivirus反向遗传学至关重要.

关键词:

在RNA病毒的RNA病毒中.卡利西病毒 (calicivirus) 是一种病毒.传染性的克隆病毒.反向遗传学是一种反向遗传学.

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
