The coronavirus spike (S) protein mediates infection of receptor-expressing host cells and is a critical target for antiviral neutralizing antibodies. Angiotensin-converting enzyme 2 (ACE2) is a functional receptor for the coronavirus (severe acute respiratory syndrome (SARS)-CoV) that causes SARS. Here we demonstrate that a 193-amino acid fragment of the S protein (residues 318-510) bound ACE2...
A respiratory disease caused by a novel coronavirus, termed the severe acute respiratory syndrome coronavirus (SARS-CoV), was first reported in China in late 2002. The subsequent efficient human-to-human transmission of this virus eventually affected more than 30 countries worldwide, resulting in a mortality rate of ~10% of infected individuals. The spread of the virus was ultimately contr...
In December 2019, the prevalence of a pneumonia with unknown cause was reported in China which was later named Coronavirus Disease 2019 (COVID-19) caused by a virus called SARS-CoV-2. One of the most important ways of COVID-19 transmission is contaminated surfaces. In this review study, we investigated the stability of SARS-CoV-2 in air and on surfaces and the methods of preventing its spread R...
BACKGROUND The emergence of severe acute respiratory syndrome (SARS) in 2002 and 2003 affected global health and caused major economic disruption. Adequate animal models are required to study the underlying pathogenesis of SARS-associated coronavirus (SARS-CoV) infection and to develop effective vaccines and therapeutics. We report the first findings of measurable clinical disease in nonhuman p...
A new coronavirus (severe acute respiratory syndrome coronavirus [SARS-CoV]) has been identified to be the etiological agent of severe acute respiratory syndrome. Given the highly contagious and acute nature of the disease, there is an urgent need for the development of diagnostic assays that can detect SARS-CoV infection. For determination of which of the viral proteins encoded by the SARS-CoV...
Given the potential for laboratory-associated severe acute respiratory syndrome-associated coronavirus (SARS-CoV) infections, we must know which cell lines are susceptible to the virus. We investigated 21 cell lines routinely used for virus isolation or research. After infection with SARS-CoV, cells were observed for cytopathic effects, and quantitative real-time polymerase chain reaction was u...
Bats are reservoirs for emerging zoonotic viruses that can have a profound impact on human and animal health, including lyssaviruses, filoviruses, paramyxoviruses, and severe acute respiratory syndrome coronaviruses (SARS-CoVs). In the course of a project focused on pathogen discovery in contexts where human-bat contact might facilitate more efficient interspecies transmission of viruses, we su...
The life cycle of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) involves a unique process called discontinuous transcription by which a set of 3' coterminal subgenomic mRNAs (sgmRNA) with identical 5' leader sequences can be generated. The current study demonstrates that the replication intermediates of minus strand of subgenomic RNA (sgRNA) can be readily recovered from SARS-CoV inf...
SARS-CoV-2 is a type of coronavirus that causes COVID-19 disease. The virus can infect various organs by triggering hormones, regulatory and messenger molecules, and immune-inflammatory responses. Given the vital role of thyroid in metabolism, it is important to understand the potential effects of SARS-CoV-2 on the thyroid gland. In this article, reports and studies examining the effects of SAR...
The severe acute respiratory syndrome coronavirus (SARS-CoV) nsp1 protein has unique biological functions that have not been described in the viral proteins of any RNA viruses; expressed SARS-CoV nsp1 protein has been found to suppress host gene expression by promoting host mRNA degradation and inhibiting translation. We generated an nsp1 mutant (nsp1-mt) that neither promoted host mRNA degrada...
