Investigate host-pathogen interaction in ASF infection

Research Question

  • To gain an improved understanding of how ASFV enters, replicates and survives in and is released from infected cells

Research Gaps and Challenges

  • Determine patterns of activation of immunologically relevant host genes particularly at early stages after infection
  • Identify ASFV genes and genetic determinants (group of genes like multigene families) involved in host range, virulence and pathogenicity

State Of the Art

  • The primary cell types infected by ASFV are those belonging to the mononuclear- phagocytic system, including fixed tissue macrophages and
    specific lineages of reticular cells. Pathological findings in acute ASF include leukopenia B and T cell lymphopenia / thrombocytopenia
    lymphocyte and mononuclear cell apoptosis
  • ASFV exhibit temporal regulation of gene expression. ASFV virions contain enzymatic activities that contribute to early events in, and activities
    critical for, viral replication in the cell cytoplasm, including RNA polymerase, nucleoside triphosphate phosphohydrolase, topoisomerase,
    mRNA capping, and protein kinase activity. ASFV encodes proteins predicted to mediate virus–host interaction, virulence, and mechanisms
    that enhance the ability of the virus to successfully replicate within the host, including homologs of cellular inhibitor of apoptosis (IAP), Bcl-2, I
    Kappa B (IKB) myeloid differentiation primary response antigen MyD116, lectin-like, and CD2 proteins
