Activation of glial cells by human coronavirus OC43 infection

Acute and persistent infection of human neural cell lines by human coronavirus OC43.

Human coronaviruses (HuCV) are recognized respiratory pathogens. Data accumulated by different laboratories suggest their neurotropic potential. For example, primary cultures of human astrocytes and microglia were shown to be susceptible to an infection by the OC43 strain of HuCV (A. Bonavia, N. Arbour, V. W. Yong, and P. J. Talbot, J. Virol. 71:800-806, 1997). We speculate that the neurotropis...

Genetic variability of human respiratory coronavirus OC43.

Human Coronavirus OC43 Associated with Fatal Encephalitis.

To the Editor: Encephalitis is a serious neurologic syndrome characterized by brain inflammation that may be fatal. Although the majority of cases are caused by viruses, the identification of a causal organism can be difficult. Encephalopathy that affects patients with immunodeficiency is particularly challenging to diagnose, since the clinical presentation may be atypical and the differential ...

Interferon induction of IFITM proteins promotes infection by human coronavirus OC43.

IFNs are a family of cytokines that are essential for the antiviral response in vertebrates. Not surprisingly, viruses have adapted to encode virulence factors to cope with the IFN response. Intriguingly, we show here that all three types of interferons, IFN-α, IFN-γ, and IFN-λ, efficiently promote infection by a human coronavirus, HCoV-OC43, one of the major etiological agents of common cold, ...

An outbreak of coronavirus OC43 respiratory infection in Normandy, France.

The 2 groups of human coronaviruses (HCoVs) represented by the prototype strains HCoV 229E and HCoV OC43 are mostly known as viruses responsible for common cold syndrome. HCoVs are difficult to detect, and epidemiological data are rare. From October 2000 through April 2001, we tested 1803 respiratory samples for HCoV by reverse-transcriptase polymerase chain reaction. From 8 February through 27...
