概括
在患有围产期艾滋病毒 (PHIV) 的儿童早期开始抗逆转录病毒治疗 (ART) 会减轻长期的炎症. 早期开始ART (≤6个月) 导致血炎症标志物较晚治疗相比较低,表明持久的免疫效益.
科学领域:
- 免疫学 免疫学 免疫学
- 病毒学 病毒学
- 儿科 儿科 儿科
背景情况:
- 抗逆转录病毒治疗 (ART) 对患有围产期艾滋病毒 (PHIV) 的儿童的长期免疫效应需要进一步阐明.
- 研究ART启动时间对PHIV儿童免疫特征的影响至关重要.
研究的目的:
- 确定ART启动的时间如何影响PHIV儿童的长期免疫特征.
- 为了在早期和晚期ART治疗组之间比较血细胞因子,化学因子和腺脱氨酶 (ADA) 水平.
主要方法:
- 在早期 (≤6个月) 与晚期 (>6个月和<2年) 开始ART的PHIV参与者中比较了血细胞因子,化学因子度和ADA酶活性.
- 在治疗开始后12.5年,分析了样本.
- 与临床共变量相关联的发现.
主要成果:
- 与早期ART组相比,在晚期ART组中观察到10种细胞因子/化学因子 (例如IFNγ,IL-6,CXCL10) 和ADA的度显著更高.
- ADA水平与几个促炎性细胞因子 (例如,IFNγ,IL-17A,IL-12p70) 有显著的正相关性.
结论:
- 在PHIV儿童中,早期的ART启动 (≤6个月) 与缓和的长期血炎症特征有关.
- 延迟ART治疗,即使有病毒抑制,也与持续升高的促炎性标志物有关.

Retrovirus Life Cycles
46.3K
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...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
