Intestinal Enteroid Culture for Human Astroviruses

[Abstract]  Human astroviruses (HAstV) are non-enveloped, positive-sense single stranded RNA viruses that typically cause gastroenteritis in children, the elderly and among immunocompromised individuals. Some HAstV species have also been implicated in neurological diseases. It is important to study these viruses to understand the pathogenesis and develop therapeutics. Here we describe HAstV infection in epithelium-only human intestinal enteroids (HIE) isolated from biopsy-derived intestinal crypts. Although different HAstV clades have been propagated in transformed immortalized cell lines such as A549, Caco-2, HEK293T and Huh7.5, we chose HIE because they better mimic the human intestine and thus are more physiologically relevant. Additionally, HIE support the replication of all HAstV clades ... [摘要]  [摘要] 人类星状病毒(HAstV)是一种非包膜,正向单链RNA病毒,通常会导致儿童,老年人和免疫力低下的人群中的肠胃炎。一些HAstV物种也与神经系统疾病有关。研究这些病毒以了解其发病机理并开发治疗方法非常重要。在这里我们描述HAstV感染 从活检来源的肠隐窝中分离出的仅上皮的人肠小肠类固醇(HIE)。尽管已经在转化的永生化细胞系(例如A549,Caco-2,HEK293T和Huh7.5)中繁殖了不同的HAstV进化枝,但我们选择HIE是因为它们可以更好地模仿人的肠道,因此在生理上更相关。此外,HIE支持所有HAstV进化枝的复制,包括临床样品,因此使HIE成为研究HAstV生物学的有价值的潜在通用模型。

[背景] 人类星状病毒(HAstV)是高度流行的肠病毒,会引起从腹泻到脑炎的广泛感染。无症状,全身和肠道外感染很常见(Madeley和Cosgrove 1975;Bosch 等人,2014;Kolawole 等人,2019)。尽管具有医学重要性,但H AstV 是一些特征最弱的肠病毒。目前,已识别出三组人类AstV:经典HAstV和非经典HAstV-MLB(墨尔本),以及HAstV-VA / ...

HIV-CRISPR: A CRISPR/Cas9 Screening Method to Identify Genes Affecting HIV Replication

[Abstract]  Screening with CRISPR/Cas9 technology has already led to significant discoveries in the fields of cancer biology, cell biology and virology. Because of the relatively low false discovery rates and the ability to perform high-throughput, pooled approaches, it has rapidly become the assay of choice for screening studies, including whole-genome screens. Here, we describe a CRISPR screening protocol that allows for efficient screening of the entire life cycle of HIV-1 through packaging of the HIV-CRISPR lentiviral genomes by infecting HIV-1 virus in trans. [摘要]  [摘要 ] CRISPR / Cas9技术的筛选已经在癌症生物学,细胞生物学和病毒学领域引起了重大发现。由于相对较低的错误发现率和执行高通量,合并方法的能力,它发展迅速。成为筛选研究(包括全基因组筛选)的首选检测方法。在此,我们描述了一种CRISPR筛选方案,该方案可通过感染HIV-CRISPR慢病毒基因组来包装,从而有效筛选HIV-1的整个生命周期。病毒1 在 跨。

[背景] 遗传筛选是鉴定影响包括人类免疫缺陷病毒(HIV)在内的病毒复制的新基因的有力工具。鉴定对HIV感染重要的宿主基因有助于增强对HIV复制,进化,传播和发病机制的认识,这是关键利益所在。特别是在过去十年中,通常是干扰素(IFN)刺激基因(ISG)的HIV限制因子的发现已成为逆转录病毒学领域的关键发展。限制因子已集中在过度表达筛选上,以鉴定作用广泛的抗病毒ISG (Schoggins 等,2011)或专门针对HIV的因子(Kane 等,2016)。通过转染对HIV限制因子进行了全基因组筛选siRNA的池池在靶细胞(刘等人,2011年)。然而,这些方法缺乏稳健性,Versa的钛Lity,和高通量方面 因此,我们使用CRISPR / Cas9技术开发了一种创新的ap 方法,并依靠HIV交叉包装通过CRISPR / Cas9文库转导的细胞中表达的慢病毒基因组的能力(OhAinle ...
