Project description:Placental infection plays a central role in the pathogenesis of congenital human cytomegalovirus (HCMV) infections and is a cause of fetal growth restriction and pregnancy loss. HCMV can replicate in some trophoblast cell types, but it remains unclear how the virus evades antiviral immunity in the placenta and how infection compromises placental development and function. Human trophoblast stem cells (TSCs) can be differentiated into extravillous trophoblasts (EVTs) and syncytiotrophoblasts (STBs). This study assessed the utility of TSCs as a model of HCMV infection in the first trimester placenta. TSCs and TSC-derived EVTs and STBs were infected with HCMV (TB40/Ewt-mCherry). RNA was isolated from infected cells at 24, 48, and 72 hours post-infection and Illumina RNA-Sequencing was used to measure viral and host gene expression. Viral gene expression in TSCs does not follow the kinetic patterns observed during lytic infection in fibroblasts. Canonical antiviral responses were largely not observed in HCMV-infected TSCs and TSC-derived trophoblasts. Rather, infection dysregulated factors involved in cell identity, differentiation, and WNT signaling.
Project description:We report the transcriptome profiles of guinea pig cytomegalovirus (Caviid betaherpesvirus 2 ; GPCMV) infected and uninfected cells. RNA was harvested at an early time post-infection. Data sets from a lung fibroblast cell line (JH4), primary amnion derived cells (1° AECs), and HPV16 E6/E7-transduced amniotic epithelial cells (AECD) is shared.
Project description:Comprehensive RNA sequencing and splicing-sensitive microarray analysis of three diverse cell types infected with human cytomegalovirus (HCMV), including primary fibroblasts (HFFs), endothelial cells (ECs), and neural progenitors (NPCs) derived from embryonic stem cells. This global analysis includes both host and viral gene expression measurements, and an in-depth assessment of alternative RNA processing events. Extended comparisons were conducted through RNA sequencing analysis of human herpes simplex virus (HSV)-2 and human immunodeficiency virus type 1 (HIV-1) infections.

Project description:Human cytomegalovirus (HCMV) has profound effect on gene expression during infection of monocytes. We performed RNA-seq and RIBO-seq to analyze the extend to which HCMV reshapes the transciptome and translatome of infected monocytes.
