Abstract

The pathogenesis of severe acute respiratory syndrome-associated coronavirus (SARS-CoV) at the cellular level is unclear. No human cell line was previously known to be susceptible to both SARS-CoV and other human coronaviruses. Huh7 cells were found to be susceptible to both SARS-CoV, associated with SARS, and human coronavirus 229E (HCoV-229E), usually associated with the common cold. Highly lytic and productive rates of infections within 48 h of inoculation were reproducible with both viruses. The early transcriptional profiles of host cell response to both types of infection at 2 and 4 h postinoculation were determined by using the Affymetrix HG-U133A microarray (about 22,000 genes). Much more perturbation of cellular gene transcription was observed after infection by SARS-CoV than after infection by HCoV-229E. Besides the upregulation of genes associated with apoptosis, which was exactly opposite to the previously reported effect of SARS-CoV in a colonic carcinoma cell line, genes related to inflammation, stress response, and procoagulation were also upregulated. These findings were confirmed by semiquantitative reverse transcription-PCR, reverse transcription-quantitative PCR for mRNA of genes, and immunoassays for some encoded proteins. These transcriptomal changes are compatible with the histological changes of pulmonary vasculitis and microvascular thrombosis in addition to the diffuse alveolar damage involving the pneumocytes.

<div type="abstract" xml:lang="en">The pathogenesis of severe acute respiratory syndrome-associated coronavirus (SARS-CoV) at the cellular level is unclear. No human cell line was previously known to be susceptible to both SARS-CoV and other human coronaviruses. Huh7 cells were found to be susceptible to both SARS-CoV, associated with SARS, and human coronavirus 229E (HCoV-229E), usually associated with the common cold. Highly lytic and productive rates of infections within 48 h of inoculation were reproducible with both viruses. The early transcriptional profiles of host cell response to both types of infection at 2 and 4 h postinoculation were determined by using the Affymetrix HG-U133A microarray (about 22,000 genes). Much more perturbation of cellular gene transcription was observed after infection by SARS-CoV than after infection by HCoV-229E. Besides the upregulation of genes associated with apoptosis, which was exactly opposite to the previously reported effect of SARS-CoV in a colonic carcinoma cell line, genes related to inflammation, stress response, and procoagulation were also upregulated. These findings were confirmed by semiquantitative reverse transcription-PCR, reverse transcription-quantitative PCR for mRNA of genes, and immunoassays for some encoded proteins. These transcriptomal changes are compatible with the histological changes of pulmonary vasculitis and microvascular thrombosis in addition to the diffuse alveolar damage involving the pneumocytes.</div>
