Identity of protective antigens

Identity of protective antigens

Research Question

  • The identity of the virus components (epitopes) that the host needs to respond to prevent and/or clear infection

Research Gaps and Challenges

  • The dominant immunogens may not be the most protective, thus a range of possible antigens will need to be considered
  • Investigate gene functions
  • Investigate the need of chaperon for proper folding of proteins
  • Investigate if different antigens provoke a response in wild boars and pigs
  • Induction of a neutralising immune response

Solution Routes

  • Identify possible protective antigens in the virus genome, their expression and trial in challenge experiments
  • Identify the antigens that the host is generating Abs to and their role in protection (preventing and clearing infection)
  • Identify the antigens that are responsible for protective cellular
    responses

Dependencies

  • Identify protective mechanisms operating in immune hosts – the role of neutralising Abs and CTCs
  • The genome sequence of various virus isolates
  • Identify determinant of virulence

State Of the Art

  • Neutralising antibodies directed against virion proteins p30, p54, and p72 have been described but they are not sufficient for antibody-mediated protection
  • Partial protection was achieved using a combination of two recombinant proteins, p54 and p30, as well as with recombinant CD2-like protein but failed to give protection against highly virulent isolates
