合成生物学综述Molecular cell

Small genomes, big lessons: What viruses teach us about structure-based riboregulation.

0 次引用趋势数据不足

RNA病毒在单一分子内编码多层信息,该分子既作为蛋白质合成模板,又作为结构化调控RNA。这些结构控制病毒基因表达的关键环节,调控宿主相互作用并介导免疫逃逸。尽管RNA结构在病毒基因组中的普遍性已确立,但功能与机制研究直至近期才开始揭示这些元件如何作为调控模块影响感染结局。RNA病毒基因组紧凑、生命周期易于实验操作,是揭示核糖调控基本构件、阐明真核生物保守基因控制原理的有力模型系统。本文综述不同病毒家族中基于RNA结构的调控机制,并与真核转录组中结构介导的基因控制进行比较,强调RNA结构是基因表达的核心调控层,具有广泛的治疗与合成生物学潜力。

AI 辅助短评,基于标题和摘要整理

该综述聚焦RNA病毒中RNA结构介导的基因调控,整合多病毒家族机制证据并与真核转录组类比,提出RNA结构为基因表达中心调控层。优势在于跨体系视角与机制梳理,但属叙述性综述,未提供系统检索策略或证据分级,病毒与真核间保守性的推断需谨慎解读。对治疗与合成生物学潜力的论述宜视为展望而非已验证结论。

Remibrutinib versus teriflunomide in relapsing multiple sclerosis (REMODEL-1 and REMODEL-2): two randomised, phase 3 trials.

0 次引用趋势数据不足

Remibrutinib是一种高选择性、强效、共价、可穿透中枢神经系统的口服BTK抑制剂。REMODEL-1和REMODEL-2为两项相同的随机、双盲、双模拟、活性对照、平行组、事件驱动Ⅲ期试验,在46个国家407个中心开展,纳入18-55岁、EDSS评分0-5.5、有近期疾病活动证据的复发型多发性硬化患者,按1:1随机接受口服remibrutinib 100 mg每日两次或特立氟胺14 mg每日一次,主要终点为年化复发率(ARR)。2021年12月13日至2025年12月30日筛查2632例,随机分配2007例;REMODEL-1纳入1000例,REMODEL-2纳入1007例。remibrutinib组ARR显著低于特立氟胺组:REMODEL-1为0.073 vs 0.112(RR 0.648,95%CI 0.453-0.927;p=0.018),REMODEL-2为0.080 vs 0.116(RR 0.688,95%CI 0.487-0.972;p=0.034)。最常见不良事件为上呼吸道感染、鼻咽炎、腹泻和脱发;导致停药的不良事件remibrutinib组较少(3.1% vs 5.8%),安全性与其他适应症一致,无肝脏安全性担忧。研究表明remibrutinib优于特立氟胺且安全性良好,支持其作为复发型多发性硬化潜在新型口服治疗选择。

Graft-versus-host disease prophylaxis shapes T cell biology and immune reconstitution after hematopoietic cell transplant.

0 次引用趋势数据不足

一项3期BMT CTN 1703试验显示,基于移植后环磷酰胺(PT-Cy)的移植物抗宿主病(GVHD)预防方案较他克莫司/甲氨蝶呤(Tac/MTX)可改善无GVHD/无复发生存,但其T细胞生物学机制尚不明确。为此,324例患者纳入BMT CTN 1801研究,通过测序2359份纵向样本及180 432 350个T细胞,评估T细胞受体(TCR)库等免疫重建路径。多模式分析显示,PT-Cy与全T细胞删除相关,随后T细胞从较小奠基群体延迟扩增,形成T细胞多样性瓶颈,导致移植后2年内TCR库多样性降低。在不考虑研究分组时,TCR多样性降低与慢性GVHD保护相关,且在PT-Cy患者中更常见。供者/宿主特异性TCR克隆分析表明,PT-Cy介导的T细胞清除亦清除病原体特异性TCR,使PT-Cy患者移植早期更可能缺乏可检测的移植物来源病原体特异性TCR,并与严重感染风险增加相关。

Comparative screening identifies gga-miR-204 as a nutrient-responsive miRNA that targets MAP1LC3B and promotes infectious bursal disease virus replication in HD11 cells.

0 次引用趋势数据不足

传染性法氏囊病病毒(IBDV)是危害养禽业的重要免疫抑制性病原。为系统识别调控IBDV复制的营养响应性microRNA(miRNA),本研究在鸡HD11巨噬细胞中建立氨基酸和葡萄糖饥饿模型,并结合IBDV感染相关miRNA谱进行比较筛选。结果显示,短期营养剥夺改变LC3相关分子表型并降低IBDV VP2蛋白表达;小RNA测序显示营养饥饿与IBDV感染诱导的miRNA表达谱存在差异但部分重叠,预测靶基因主要富集于代谢和应激反应通路。gga-miR-204在氨基酸和葡萄糖饥饿下上调、在IBDV感染后下调。功能实验表明,过表达gga-miR-204可提高病毒RNA水平、VP2蛋白表达和感染性病毒产量,而抑制内源性gga-miR-204则抑制IBDV复制。报告基因实验支持gga-miR-204靶向鸡MAP1LC3B 3'非翻译区,模拟物处理降低HD11细胞中LC3-II水平;沉默MAP1LC3B增加VP2丰度,过表达MAP1LC3B则降低VP2丰度。研究提示,gga-miR-204为营养响应性miRNA,可促进HD11细胞中IBDV复制,MAP1LC3B为对VP2丰度具有功能影响的候选靶标;MAP1LC3B是否介导gga-miR-204的促病毒效应尚待确定。

本研究在HD11细胞中整合营养饥饿与IBDV感染miRNA谱,筛选出gga-miR-204并完成过表达/抑制及报告基因等功能验证。结果支持其促病毒复制及靶向MAP1LC3B,但MAP1LC3B是否介导该促病毒效应尚未确立,作者对此表述谨慎。总体证据链较完整,机制仍属候选关联,需进一步因果验证。
