Project description:Coronaviruses express a repertoire of accessory proteins for evading host immune responses. Among these accessory proteins, a small internal (I) protein is expressed by members of the genus Betacoronavirus. Previous studies reported that the I proteins of SARS-CoV, MERS-CoV and SARS-CoV-2 inhibit type I interferon (IFN-I) expression through distinct mechanisms and play different roles in pathogenesis. In addition, human coronaviruses HKU1 and OC43 are betacroaonvairuses that predominantly cause common cold and encode the I protein as one of their accessory proteins; the I proteins of hCoV-HKU1 and hCoV-OC43 have not been previously characterized. However, the lack of robust reverse genetic systems, tissue culture and animal models limit the study of hCoV-HKU1 and hCoV-OC43 pathogenesis. Here, we examined the role of hCoV-HKU1 and hCoV-OC43 I proteins in pathogenesis using a prototypic coronavirus. We introduced the I proteins of hCoV-HKU1 and hCoV-OC43 independently to a neurotropic strain of mouse hepatitis virus (MHV-J2.2). MHV-J2.2 infection is well-characterized with clearly defined immune responses which allows the study of I proteins in the context of authentic coronavirus infection. We showed that the I protein of hCoV-HKU1 but not that of hCoV-OC43 ameliorated MHV-J2.2 infection while the I protein of MERS-CoV causes exacerbated disease. Further analysis revealed that infection with MHV-J2.2 expressing the I protein of MERS-CoV leads to increased neutrophil infiltration to the site of infection and virus titers in mice; diminished virus titers was observed in the presence of hCoV-HKU1 I protein. Overall, our findings suggest that the I protein of different betacoronaviruses play unique roles in pathogenesis.

Project description:Seasonal coronaviruses, including HCoV-229E, -NL63, -OC43, and -HKU1, are prevalent worldwide, predominantly causing mild, self-limiting upper respiratory (re-)infections in adults, often presenting as the common cold. However, in individuals with compromised immune systems, these viruses may lead to more severe illness and even fatalities. Recently, there has been a renewed interest in studying HCoVs due to their amenability to handling in reduced biosafety containment, offering valuable alternatives to SARS-CoV-2 for preclinical screening and the development of antiviral treatments. Despite their significance, research on HCoVs has been hindered by limited host-genomic data. To address this, we performed RNA-sequencing on 3D air-liquid interface human nasal airway epithelial cells (hNECs) infected with the alphacoronavirus HCoV-229E and the betacoronavirus HCoV-OC43. These hNECs were derived from pooled adult donors and exhibited pseudostratified mucociliated differentiation, faithfully replicating the complexities of normal airway biology. Our study aimed to identify specific immune signatures associated with HCoV infections in a physiologically relevant model. By elucidating the host responses induced by different seasonal coronaviruses, we can gain valuable insights into their pathogenesis and interactions with the respiratory epithelium. This knowledge may pave the way for the development of targeted therapeutics and prophylactics to combat HCoV infections effectively.

Project description:The emergence of novel betacoronaviruses has posed significant financial and human health burdens, necessitating the development of appropriate tools to combat future outbreaks. In this study, we have characterized a human cell line, IGROV-1, as a robust tool to detect, propagate, and titrate betacoronavirus SARS-CoV-2 and HCoV-OC43. IGROV-1 cells can be used for serological assays, antiviral drug testing, and isolating SARS-CoV-2 variants from patient samples. Using time-course transcriptomics, we confirmed that IGROV-1 cells exhibit a robust innate immune response upon SARS-CoV-2 infection, recapitulating the response previously observed in primary human nasal epithelial cells. We performed genome-wide CRISPR knockout genetic screens in IGROV-1 cells and identified Aryl hydrocarbon receptor (AHR) as a critical host dependency factor for both SARS-CoV-2 and HCoV-OC43. Using DiMNF, a small molecule inhibitor of AHR, we observed that the drug selectively inhibits HCoV-OC43 infection but not SARS-CoV-2. Transcriptomic analysis in primary normal human bronchial epithelial cells revealed that DiMNF blocks HCoV-OC43 infection via basal activation of innate immune responses. Our findings highlight the potential of IGROV-1 cells as a valuable diagnostic and research tool to combat betacoronavirus diseases.

Project description:Understanding how human coronavirus dysregulate host proteome during infection in human cells will identify general pathways that are common to coronavirus infection. NMS-873 is an allosteric p97/VCP ATPase inhibitor and was show to have antiviral effect in multiple viruses including SARS-CoV2. We first demonstrated that genetic knock down of p97 reduced HCoV-229E, HCoV-OC43 infection and secretion. To investigate how p97/VCP assists virus infection, we used unbiased quantitative proteomics to compare dysregulated proteomes caused by HCoV-229E, HCoV-OC43 and SARS-CoV2 infection. We then compared dysregulated proteomes after HCoV-229E and HCoV-OC43 infection with and without p97 knockdown. Moreover, we elucidated the impact of p97 on different stages of viral life cycle using two potent p97 inhibitors, CB-5083 and NMS-873 and demonstrate their can block HCoV replication. Together, our data provide insights to repurpose potential cancer drugs that target the essential host protein p97/VCP.

Project description:Differential expression was determined in Calu-3 cells between mock infected and infection with either Human coronavirus EMC and SARS coronavirus at different times post infection. Calu-3 2B4 cells were infected with Human Coronavirus EMC 2012 (HCoV-EMC) or mock infected. Samples were collected 0, 3, 7, 12, 18 and 24 hpi. There are 3 mock and 3 infected replicates for each time point, except for 12 hpi for which there are only 2 infected replicates (one replicate did not pass RNA quality check). There were no mock sampes at 18 hpi, and therefore infected samples at 18 hpi were compared with mocks at 24 hpi. For direct comparison with SARS-CoV infected cells, raw data from HCoV-EMC experiments were quantile normalized together with the SARS-CoV dataset (GEO Series accession number GSE33267).
