Severe acute respiratory syndrome-coronavirus (SARS-CoV) evades the host innate immune system. SARS-CoV antagonizes interferon pathways, impacting viral pathogenesis and disease severity.

Area of Science:

  • Virology
  • Immunology
  • Pathogenesis

Background:

  • The emergence of SARS-CoV has increased focus on coronavirus biology.
  • Host-pathogen interactions, particularly with the innate immune system, are crucial for SARS-CoV virulence.

Purpose of the Study:

  • To review in vivo interplay between SARS-CoV and innate immunity.
  • To discuss in vitro mechanisms of viral antagonism of host immune responses.

Main Methods:

  • Review of current knowledge on SARS-CoV and innate immunity.
  • Analysis of specific SARS-CoV gene products' effects on host immune signaling in cell culture.

Main Results:

  • SARS-CoV employs strategies to antagonize host interferon sensing and signaling pathways.

  • Specific viral gene products interfere with innate immune responses.

    • Conclusions:

    • Understanding SARS-CoV immune evasion is key to understanding pathogenesis.
    • Identifying mechanisms of immune antagonism can inform strategies against severe disease.
