Project description:HAE cultures were infected with SARS-CoV, SARS-dORF6 or SARS-BatSRBD and were directly compared to A/CA/04/2009 H1N1 influenza-infected cultures. Cell samples were collected at various hours post-infection for analysis. Time Points = 0, 12, 24, 36, 48, 60, 72, 84 and 96 hrs post-infection for SARS-CoV, SARS-dORF6 and SARS-BatSRBD. Time Points = 0, 6, 12, 18, 24, 36 and 48 hrs post-infection for H1N1. Done in triplicate for RNA Triplicates are defined as 3 different wells, plated at the same time and using the same cell stock for all replicates. Time matched mocks done in triplicate from same cell stock as rest of samples. Culture medium (the same as what the virus stock is in) will be used for the mock infections. Infection was done at an MOI of 2 for SARS viruses and an MOI of 1 for H1N1.

Project description:The coronavirus disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), remains to spread worldwide. COVID-19 is characterized by the striking high mortality in elderly; however, its mechanistic insights remain unclear. Systemic thrombosis has been highlighted in the pathogenesis of COVID-19, and lung microangiopathy in association with endothelial cells (ECs) injury has been reported by post-mortem analysis of the lungs. Here, we experimentally investigated the SARS-CoV-2 infection in cultured human ECs, and performed a comparative analysis for post-infection molecular events using early passage and replicative senescent ECs. We found that; 1) SARS-CoV-2 infects ECs but does not replicate and disappears in 72 hours without causing severe cell damage, 2) Senescent ECs are highly susceptible to SARS-CoV-2 infection, 3) SARS-CoV-2 infection alters various genes expression, which could cause EC dysfunctions, 4) More genes expression is affected in senescent ECs by SARS-CoV-2 infection than in early passage ECs, which might causes further exacerbated dysfunction in senescent ECs. These data suggest that sustained EC dysfunctions due to SARS-CoV-2 infection may contribute to the microangiopathy in the lungs, leading to deteriorated inflammation and thrombosis in COVID-19. Our data also suggest a possible causative role of EC senescence in the aggravated disease in elder COVID-19 patients.

Project description:SARS-CoV and SARS-CoV-2, the causative agents of severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19), are genetically related positive-sense RNA viruses that may cause similar pathophysiology. Despite host could activate interferon responses upon coronaviral infection to suppress virus replication, both SARS-CoV and SARS-CoV-2 have evolved strategies to inhibit interferon response. Here, we constructed SARS-CoV and SARS-CoV-2 N proteins expressing cell lines (HEK293T-N and HEK293T-2N) and performed RNA sequencing analysis, showing that both SARS-CoV-2 and SARS-CoV N proteins could inhibit expression of early growth response gene 1 (EGR1) to suppress interferon response. Moreover, EGR1 could degrade N proteins of SARS-CoV and SARS-CoV-2 in a lysosome-dependent manner, and inhibit viral replication of SARS-CoV-2. Our findings revealed the important role of EGR1 in host innate immune response against SARS-CoV and SARS-CoV-2, which would contribute to understanding the pathogenesis of human coronaviruses and development of antiviral therapies. In addition, we demonstrated that both N proteins could upregulate expression of nervous development-related genes, which may be associated with the neurological symptoms of COVID-19 and SARS patients.

Project description:For the assessment of host response dynamics to SARS-CoV and SARS-CoV-2 infections in human airway epithelial cells at ambient temperature corresponding to the upper or lower respiratory tract. We performed a temporal transcriptome analysis on human airway epithelial cell (hAEC) cultures infected with SARS-CoV and SARS-CoV-2, as well as uninfected hAEC cultures, incubated either at 33°C or 37°C. hAEC cultures were harvested at 24, 48 72, 96 hpi and processed for Bulk RNA Barcoding and sequencing (BRB-seq), which allows a rapid and sensitive genome-wide transcriptomic analysis in a highly multiplexed manner. Transcriptome data was obtained from a total of 7 biological donors for pairwise comparisons of SARS-CoV or SARS-CoV-2 virus-infected to unexposed hAEC cultures at respective time points and temperatures.
