Abstract
Granulomas are inflammatory tissue responses directed to a set of antigens. Trapped Schistosoma mansoni eggs promote productive granulomas in the tissues, and they are the main damage caused by schistosomiasis. Some S. mansoni antigenic proteins may have a direct involvement in the resolution of the granulomatous response. The ATP diphosphohydrolases isoforms of this parasite are immunogenic, expressed in all phases of the parasite life cycle and secreted by eggs and adult worms. Potato apyrase is a vegetable protein that cross-reactive with parasite ATP diphosphohydrolases isoforms. In this study, the vegetable protein was purified, before being inoculated in C57BL/6 mice that were later infected with cercariae. Sixty days after infection, adult worms were recovered, antibodies and cytokines were measured, and morphological granuloma alterations evaluated. Immunization of the animals induced significant levels of IgG and IgG1 antibodies and IFN-γ, IL-10 and IL-5 cytokines, but not IL-13, suggesting that potato apyrase is an immunoregulatory protein. Supporting this hypothesis, it was found that liver damage associated with schistosomiasis was mitigated, reducing the size of the areas affected by granuloma to 35% and increasing the presence of multinucleated giant cells in this environment. In conclusion, potato apyrase was found to be effective immunomodulatory antigen for murine schistosomiasis.

Abstract
A polypeptide (r78-117) belonging to the potato apyrase was identified as a conserved domain shared with apyrase-like proteins from distinct pathogenic organisms, and was obtained as a 6xHis tag polypeptide (r-Domain B). By ELISA, high IgG, and IgG1 and IgG2a subtypes levels were detected in BALB/c mice pre-inoculated with r-Domain B. In Schistosoma mansoni adult worm or Leishmania (V.) braziliensis promastigote preparation, anti-r-Domain B antibodies inhibit 22-72% of the phosphohydrolytic activities and when immobilized on Protein A-Sepharose immunoprecipitate 42-91% of them. Western blots of the immunoprecipitated resin-antibody-antigen complexes identified bands of mw similar to those predicted for parasite proteins. Total IgG and subclasses of patients with leishmaniasis or schistosomiasis exhibited cross-immunoreactivity with r-Domain B. Therefore, the domain B within both S. mansoni SmATPDase 2 (r156-195) and L. (V.) braziliensis NDPase (r83-122) are potentially involved in the host immune response, and also seem to be conserved during host and parasites co-evolution.
