Project description:Bat adenoviruses are a group of recently identified adenoviruses (AdVs) which are highly prevalent in bats yet share low similarity to known AdVs from other species. In this study, deep RNA sequencing was used to analyze the transcriptome at five time points following the infection of a bat AdV in a kidney cell line derived from a myotis bat species. Evidence of AdV replication was observed with the proportion of viral RNAs ranging from 0.01% at 6 h to 1.3% at 18 h. Further analysis of viral temporal gene expression revealed three replication stages; the early stage genes encoding mainly for host interaction proteins, the intermediate stage genes for the DNA replication and assembly proteins, and the late stage genes for most structural proteins. Several bat AdV genes were expressed at stages that differed from their counterpart genes previously reported for human AdV. In addition, single-base resolution splice sites of several genes and promoter regions of all 30 viral genes were fully determined. Simultaneously, the temporal cellular gene expression profiles were identified. The most overrepresented functional categories of the differentially expressed genes were related to cellular immune response, transcription, translation, and DNA replication and repair. Taken together, the deep RNA sequencing provided a global, transcriptional profile of the novel BtAdV and the virus-host interactions, which will be useful for the understanding and investigation of AdV replication, pathogenesis and specific virus-bat interactions in future research. Deep RNA sequencing was used to analyze the transcriptome at five time points(0h,6h,8h, 12h 18h) following the infection of a bat AdV in a bat kidney cell.

Project description:Zoonotic influenza A viruses of avian origin can cause severe disease in individuals, or even global pandemics, and thus pose a threat to human populations. Waterfowl and shorebirds are believed to be the reservoir for all influenza A viruses, but this has recently been challenged by the identification of novel influenza A viruses in bats. The major bat influenza A virus envelope glycoprotein, haemagglutinin, does not bind the canonical influenza A virus receptor, sialic acid or any other glycan, despite its high sequence and structural homology with conventional haemagglutinins. This functionally uncharacterized plasticity of the bat influenza A virus haemagglutinin means the tropism and zoonotic potential of these viruses has not been fully determined. Here we show, using transcriptomic profiling of susceptible versus non-susceptible cells in combination with genome-wide CRISPR-Cas9 screening, that the major histocompatibility complex class II (MHC-II) human leukocyte antigen DR isotype (HLA-DR) is an essential entry determinant for bat influenza A viruses. Genetic ablation of the HLA-DR α-chain rendered cells resistant to infection by bat influenza A virus, whereas ectopic expression of the HLA-DR complex in non-susceptible cells conferred susceptibility. Expression of MHC-II from different bat species, pigs, mice or chickens also conferred susceptibility to infection. Notably, the infection of mice with bat influenza A virus resulted in robust virus replication in the upper respiratory tract, whereas mice deficient for MHC-II were resistant. Collectively, our data identify MHC-II as a crucial entry mediator for bat influenza A viruses in multiple species, which permits a broad vertebrate tropism.

Project description:SILAC labeled human kidney cells (293 cells) or bat kidney cells (PakiT03cells)were infected with Hendra virus for 8 or 24 hours and compared to uninfected control cells. Protein identification and quantitation relied on a combination of Uniprot lists of proteins and Proteomics Informed by Transcriptomics (PIT) analysis whereby RNA extracted from the same samples was deep sequenced and the sequencing data was used to construct mRNA from which possible ORFS were inferred and used as a search space by MaxQuant.

Project description:Jamaican fruit bats (Artibeus jamaicensis) naturally harbor a wide range of viruses of human relevance. These infections are typically mild in bats, suggesting unique features of their immune system. To better understand the immune response to viral infections in bats, we infected Jamaican fruit bats with the bat-derived influenza A virus H18N11. Using comparative single-cell RNA sequencing, we generated a single-cell atlas of the Jamaican fruit bat intestine and mesentery, the target organs of infection. Gene expression profiling showed that H18N11 infection resulted in a moderate induction of interferon-stimulated genes and transcriptional activation of immune cells. H18N11 infection was prominent in various leukocytes, including macrophages, B cells, and NK/T cells. Confirming these findings, human leukocytes, particularly macrophages, were also susceptible to H18N11, highlighting the zoonotic potential of this virus. Our study provides insight into the virus-host relationship and thus serves as a fundamental resource for further characterization of bat immunology.
