Project description:Swiss murine embryonic fibroblasts (NIH-3T3) were infected with wild-type Smith strain mouse cytomegalovirus (MCMV) at a multiplicity of infection (MOI) of 10. Ribosome profiling was performed at various times during infection with minor modification to the protocol described in Stern-Ginossar N et al., Science 2012. The detailed protocol is described in Rutkowski et al, Nature commun 2015, and Whisnant et al., Nature commun. 2020. Translation start site profiling was performed by culturing cells in presence of Harringtonin or Lactimidomycin for 30 min prior to cell harvest.

Project description:Swiss murine embryonic fibroblasts (NIH-3T3) were infected with wild-type Smith strain mouse cytomegalovirus (MCMV) at a multiplicity of infection (MOI) of 10. Metabolic RNA labelling was performed using 400µM 4sU for one hour prior to cell lysis. Total RNA was isolated using the Trizol protocol and U-to-C conversions were induced by IAA treatment according to the SLAM-seq protocol (Herzog et al., Nature Methods 2017). Sequencing libraries were prepared using the dRNA-seq protocol from the indicated time points of infection as described by Whisnant A.W. et al, Nat. Commun (2020).

Project description:Prenatal Human Cytomegalovirus (HCMV) infection often causes CNS maldevelopment. In a murine model, we detect Murine Cytomegalovirus (MCMV) in brain following intra-peritoneal inoculation at birth. Infected mice show impaired cerebellar development and impaired neurologic function on a beam balance test as adults. Among developmental genes differentially regulated, hindbrain expression of the homeodomain transcription factor HOXa5 was reduced with infection, and fewer HOXa5 expressing neurons were found in vestibular nuclei. Based on the hypothesis that immune activation connects focal viral infection and global CNS maldevelopment, we defined the components of CNS immune response. Flow cytometry showed a large increase in both number and activation of CNS monocytes. Monocytes were found in close association with infected cells by immunohistochemistry (IHC). Oligonucleotide microarrays contained herein identified many differentially expressed genes related to innate immune response. Chemokines, cytokines, cell surface receptors, and proteases are some of the many immunological genes shown to be differentially regulated by MCMV infection. These results together show that MCMV infection induces a complex immune response associated with changes in developmental gene expression and lasting neurologic defecit. Keywords: disease state comparison (virus infection) and competetive hybridization for expression analysis Previous work empirically determined the kinetics of viral spread to and replication in the Balb-C murine CNS. Balb-C mice were inoculated intra-peritoneally at birth, and harvested at 5, 8, 12, and 21 days post inoculation for cerebellar experiments. Controls were mock infected with vehicle (DMEM cell growth media) and harvested at the same timepoints. Each microarray was a two channel MEEBO array, upon which labeled and reverse transcribed cDNA from 3 pooled infected cerebella and three pooled uninfected cerebella competetively hybridized. Three unique biological replicates were performed with day 5 cDNA, 5 unique biological replicates at day 8, 5 unique biological replicates at day 12, and 4 unique biological replicates at day 21. For the analysis, colors channels were seperated and treated as independent hybridizations. However, since the experiments were dual channel, the primary data may be employed to generate ratio based measurements, and each sample is provided a corresponding number that can be used to pair the processed data and derive ratios (mock 3, infected 3). Mice were similarly inoculated and harvested at 5, 15, and 21 days post natal for liver tissue analysis. Inoculation was performed by injection with a microsyringe of 50ul titered virus delivering 500-1000 PFU per animal.

Project description:The systematic temporal gene expression analysis of primary macrophages activated under immune (interferon-gamma) and productive viral infection with murine cytomegalovirus (mCMV). The primary objective of the study is to define, in an unbiased manner, cause-and-effect relationships in the program of gene activation in this cellular system. The even spacing and time intervals (every 30 minutes) makes this study amenable to modelling of gene networks in the system. A kinetic analysis of mCMV infection on the gene expression of murine (BALB/c) bone marrow-derived macrophages (BMDMs) over the first 12 hours, sampling every 30 minutes. Agilent mouse genome arrays were used to determine the differences in gene expression between mock and mCMV infected. The 25 samples collected for the mock infected were pooled and treated as a pooled control. Pooled control was labelled with Cy3 dye and hybridised with every other sample (labelled with Cy5 dye) = 25 dual-dye array hybridisations. The reference channel of the dual-channel hybridisations was only used to normalise the expression of the test channel, rather than used to calculate ratio data. Thus, the normalised data represent log2 single-channel data.

Project description:Ly49G2+ NK cells mediate essential control of murine cytomegalovirus (MCMV) infection in mice which express the H-2Dk class I molecule. As a cognate ligand for specific Ly49G2 inhibitory receptor allotypes, H-2Dk also licenses Ly49G2+ NK cells in naïve and MCMV-infected mice. These findings suggest Ly49G2 may promote antiviral NK cell activities during MCMV infection. Indeed, in mice lacking the Ly49G2 receptor, MCMV resistance is fully abrogated. Additionally, NK cells expressing Ly49R, an NK cell associated activation receptor that also recognizes H-2Dk, have their function augmented by Ly49G2 and are required for MCMV resistance.

Project description:Evidence supporting the role of pathogen exposure in the development of dementia has been mounting for decades. We used murine cytomegalovirus (MCMV) as our model pathogen. We repeated infected mice every 3 months modeling the re-activation/re-infection with MCMV that occurs throughout life. We used Multiome ATAC-seq and RNA-seq to examine changes to the brain of infected animals.
