流行病学流行病学
病毒学病毒学
公共卫生公共卫生

背景情况:

艾滋病毒抗药性 (HIVDR) 对全球艾滋病流行病控制构成重大威胁.
抗逆转录病毒疗法 (ART) 的扩大增加了HIVDR的风险.
了解耐药性模式对于有效的艾滋病毒管理至关重要.

研究的目的:

调查HIV治疗前耐药性 (PDR) 的流行病学动态.
描述PDR和获得药物耐药性 (ADR) 的分子方面.
分析中国杭州的HIVDR,这是一个主要的发达地区.

主要方法:

从2020年到2023年进行了一项流行病学调查.
包括3,596例新诊断的艾滋病毒感染病例和164例ART失败病例.

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...

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
