概括
尽管有效治疗,但HIV-1仍在组织中存在,但完整的病毒不会对多卢特格拉维尔产生耐药性突变. 可检测到的HIV-1RNA很可能来自有缺陷的前病毒DNA.
科学领域:
- 病毒学 病毒学
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
背景情况:
- 有限的研究存在于现代抗逆转录病毒疗法 (ART) 治疗HIV-1 (PLWH) 感染者组织中的HIV-1持久性.
- 第二代整合酶抑制剂,如杜洛特格拉维尔,是非常有效的,但它们对组织储存物的影响尚未完全理解.
研究的目的:
- 调查基于多卢特格拉维尔的ART在PLWH中可访问的解剖部位的HIV-1持久性.
- 量化HIV-1DNA和RNA水平,评估药物耐药性突变 (DRM),并分析各种组织中的病毒多样性.
主要方法:
- 在ANRS EP64 DOLUVOIR研究中,纳入了20个PLWH,其病毒载量抑制 (<50副本/毫升) 含有杜洛特格拉维尔的ART.
- 在PBMC,直肠,脂肪组织,淋巴结和精子中测量了HIV-1 DNA和与细胞相关的HIV-1 RNA.
- 测序了DRM和多样性的HIV-1DNA;在PBMC中估计了完整的前病毒DNA.
主要成果:
- 在淋巴结,PBMC,脂肪组织和直肠中检测到HIV-1DNA和RNA,淋巴结的水平最高.
- 除了一个样本外,HIV-1 DNA在精子中基本上无法检测到.
- 在6名参与者中发现了药物耐药性突变 (DRM),只有两个主要的dolutegravir DRM (G118R,R263K) 归因于APOBEC高突变.
结论:
- 尽管正在进行转录,但组织中的完好无损的HIV-1前病毒不会发展出耐杜洛特格拉维尔突变.
- 在组织中检测到的HIV-1转录活性似乎主要来自有缺陷的前病毒DNA.
- 多卢特格拉维尔在抑制病毒复制和防止DRM在组织储存中出现方面仍然有效.

Viral Mutations
39.9K
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...

Mutations
44.5K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Gene Therapy
27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Stem Cell Therapy for Tissue Regeneration
4.7K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Mutation, Gene Flow, and Genetic Drift
64.0K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
