Project description:Congenital human cytomegalovirus (HCMV) infection is one of the leading prenatal causes of mental retardation and congenital deformities world-wide. Access to cultured human neuronal lineages, necessary to understand the species specific pathogenic effects of HCMV has been limited by difficulties in sustaining primary cultures. Neuronal cells derived from human induced pluripotent stem (iPS) cells now provide a novel opportunity to investigate HCMV pathogenesis. We derived iPS cells from human adult fibroblasts and induced neural lineages to investigate their permissiveness to infection with HCMV strain Ad169. Analysis of iPS cells and nearly pure populations of iPS-derived neural stem cells (NSCs), neuroprogenitor cells (NPCs) and neurons suggests that (i) iPS cells are not permissive to HCMV infection; (ii) Neural stem cells have impaired differentiation when infected by HCMV; (iii) NPCs are fully permissive for HCMV infection; the supernatant from infected neural stem cells and NPCs (but not mock infected cells) induced cytopathic effects in human fibroblasts; (iv) most iPS-derived neurons are not permissive to HCMV infection; and (v) infected neurons have impaired calcium influx in response to glutamate. Our approach offers powerful cellular models to investigate the effect of neurotropic viral agents on human neurodevelopment. Adherent monolayer culture of neural progenitor cells (NPCs) were either infected with HCMV Ad169 in triplicate, with each individual sample harvested separately to provide biological replicates for expression analysis. Infected and mock-infected cells were harvested 24 h p.i. RNA. NPCs were 70-80% confluence.

Project description:Congenital human cytomegalovirus (HCMV) infection is the leading infectious cause of birth defects, including neurodevelopmental disorders. HCMV infection mainly targets neural progenitor cells (NPCs) in fetal brains, inducing abnormal differentiation by altering key regulatory pathways. HCMV expresses a series of viral miRNAs during infection, but their roles, particularly in NPCs, are not fully understood. In this study, we characterized expression profiles of both cellular and viral miRNAs in HCMV-infected NPCs by microarray analysis during early infection time points and investigated the primary effects of these miRNAs on regulating NPC fate. While expression of most cellular miRNAs was unaffected by HCMV infection, one cellular miRNA was upregulated and six were downregulated from 2 to 24 h post infection. Moreover, of 17 HCMV miRNAs evaluated, six were differentially expressed in HCMV-infected NPCs during early infection time points.

Project description:To elucidate miRNA-mediated temporal crosstalk during productive infection, we identified genome-wide miRNA target sites using Argonaute-crosslinking and immunoprecipitation followed by high-throughput sequencing (AGO-CLIPseq) in human cytomegalovirus (HCMV)-infected cells and evaluated the targeting efficacy by applying our new AGO-CLIPseq enrichment (ACE)-scoring algorithm. To uncover the miRNA targetome in uninfected or infected human foreskin fibroblasts with HCMV (24, 48 and 72 post-infection hour) were subjected to take AGO-CLIPseq as well as mRNAseq/smallRNAseq.

Project description:To investigate how Roquin regulates cellular transcripts during Human cytomegalovirus (HCMV) infection, we examined the levels of cellular transcripts in cells treated control or Roquin-targeting siRNA during HCMV replication. Also, we performed Roquin crosslinking and immunoprecipitation followed by high-throughput sequencing (Roquin CLIP-seq) in HCMV-infected cells to identify which transcripts are directly bound by Roquin.
