  • The viruses that comprise the Flaviviridae family are small enveloped, single-stranded, positive-sense RNA viruses. (asmscience.org)
  • Examination of interferon (IFN) signaling in infected cells has revealed strategies by which Flaviviridae members attenuate IFN-a/β receptor signaling actions, thus limiting the downstream expression of ISGs that otherwise control virus replication and spread. (asmscience.org)

Antibodies5
  • Most animals experience acute infection, during which they either die or survive by producing neutralising antibodies to the virus. (nih.gov)
  • This effect could be neutralized by rescue of the inactivated E rns gene and by neutralizing polyclonal antibodies directed against E rns , indicating that this effect was an inherent property of the RNase-negative virus. (asm.org)
  • Antibodies-online offers ELISA kits and antibodies for research of over 150 viral targets and virus like particles to assist researchers investigating virus structure, replication, pathogenesis and evolution . (antibodies-online.com)
  • The immune response to PRRSV infection is characterized by a delayed appearance of neutralizing antibodies ( 31 ), a short cell-mediated immune response ( 34 , 59 ), and slow development of a virus-specific gamma interferon (IFN-γ) response ( 35 ). (asm.org)
  • Virus spread in various organs was followed by virus isolation, by immunohistochemistry, applying monoclonal antibodies in a two-step method and by in situ hybridisation using a digoxigenin-labelled riboprobe. (nih.gov)
