概括
新的血液生物标志物,特别是神经外外体中发现的微RNA (miRNA),显示出对诊断艾滋病毒相关神经认知障碍 (HAND) 的希望. 这些发现可能会导致对艾滋病毒感染者进行更简单的查 (PLWH).
科学领域:
- 神经科学是一个神经科学.
- 病毒学 病毒学
- 遗传学 是一个遗传学.
背景情况:
- 与艾滋病毒相关的神经认知障碍 (HAND) 损害了艾滋病毒感染者 (PLWH) 的认知和运动功能.
- 目前HAND的诊断方法涉及耗时的神经心理测试,限制了有效的查.
- 即使病毒载量被抗逆转录病毒疗法抑制时,HAND也可能发生,这突显出需要更好的诊断工具.
研究的目的:
- 为了确定基于血液的微创生物标志物用于HAND的定量诊断和查.
- 分析来自PLWH的神经元衍生外体 (神经外体) 中的microRNA (miRNA) 表达特征.
主要方法:
- 从PLWH的外周血液中分离神经外体.
- 在这些神经外生体内分析miRNA转录组.
- 在HAND PLWH,非HAND PLWH和HIV阴性对照之间比较miRNA表达水平.
主要成果:
- 在HAND PLWH中,有五种miRNAs (hsa-miR-16-5p,hsa-miR-26a-3p,hsa-92a-3p,hsa-miR-103a-3p,hsa-miR-185-5p) 的上调调.
- 在HAND PLWH中,两个miRNA (hsa-miR-3613-3p,hsa-miR-4668-5p) 的下调.
- 高水平的hsa-miR-16-5p,hsa-miR-103a-3p和hsa-miR-185-5p区分了手动PLWH与对照组和非手动PLWH.

Overview of Exosomes
2.7K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

MicroRNAs
3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
