RESEARCH INTEREST

Parasite Immunology and Molecular Biology

  • Innate and adaptive immunity against Fasciola hepatica antigens: Current studies will determine the role of fatty acid binding protein and glutathione S-transerase in the immunomodulation mechanisms used by the parasitic helminth Fasciola hepatica to induce chronic diseases and perpetuate its longevity in the mammalian host. We will focus in the interaction of these proteins with toll-like receptors of macrophages and dendritic cells.
  • The parasitic helminth Fasciola hepaticaA pharmacopeia of anti-inflammatory molecules: We are focused in the identification and characterization of parasite molecules with potential to develop novel anti-inflammatory drugs that are effective against sepsis, arthritis and ulcerative colitis. We have already identified a molecule with powerful anti-inflammatory properties termed Fh12, which is highly effective suppressing a large number of inflammatory markers and preventing the septic shock in a mouse model. Current studies will determine the effectiveness of Fh12 at early phases in a non-human primate septic shock model and will determine the spectrum of action of this molecule against a wide range of bacteria strains.
  • Proteomic and genomic: Current studies using advanced proteomic or genomic technologies will allow determine the gene expression and proteins of macrophages or dendritic cells that are down-regulated or up-regulated during exposition of phagocytes to hepatica antigens at early phases of infection. These strategies will allow elucidate the mechanisms of action of parasitic molecules and advance in our understanding of the host-parasite relationship leading the development of vaccines and novel anti-inflammatory drugs.
