Descripción: Background: Trypanosoma cruzi, the causative agent of Chagas disease contains a major antigen, cruzipain (Cz). The C-terminal domain (C-T) of this glycoprotein bears N-linked high mannose type sulfated oligosaccharide chains and is responsible for most antibodiesinnaturalandexperimentalinfections.Miceimmunization with C-T has shown that sulfate moieties of Cz molecule are targets for speciﬁc immune responses and responsible for cardiac ultrastructural abnormalities in absence of infection. Methods & Materials: After the molecular characterization of these sufotopes, BALB/c mice were immunized with Cz/C-T, prior and after desulfation treatment, and with NAcGlc6SO3-BSA, to be furthersublethallychallengedwithtrypomastigotestoinvestigate whether they are involved in immunepathogenesis and/or infection of experimental Chagas disease. Results: C-T-immunized mice showed low IL-4 levels and elevated IFN- concentration by capture ELISA using C-T as stimulus and a cytokines proﬁle compatible with a mixed response showing: Th2 tendency with excessively high IFN and raised IL-17 levels. By contrast, dC-T-immunized-mice presented undetectable IL-4 levels, low IFN- level and a cytokines proﬁle like that of control but with a signiﬁcantly elevated IL-10 value. In addition, ultrastructuralcardiacalterationsandmainimmunorecognitionof ﬁbrils and mitochondria were observed in C-T-immunized mice bothconfrontedwithpolyclonalanti-CzandmyosinadsorbedantiCz sera. After sublethal challenge, elevated parasitaemias were observed. Mortality was 20 and 80% in C-T and dC-T immunized mice, respectively and mice from dC-T group that survived presentedseveremusclealterations.BSA-NAcGlc6SO3-immunized mice mounted a predominant IgG1and IgG2b immune response followed by IgG2a, demonstrating the immunodominance of the sulfotope and a vigorous mice memory T cells response, similarly toC-T-immunizedmice.Aftersublethalinfection,miceimmunized with the sulfotope displayed excessively elevated parasitemias, similarIFN-levelsandsigniﬁcantlowermortalitypercentagethan those from BSA-NAcGlc control group. Furthermore, mice treated by passive transference of sulfate-speciﬁc IgGs puriﬁed from sera of BSA-NAcGlc6SO3-immunized mice, exhibited ultrastructural alterations in cardiac tissue. After challenge, those treated with sulfate-speciﬁc IgGs presented higher parasitemias than controls Conclusion:Altogether,theseﬁndingshavedemonstratedthat sulfotopes and their speciﬁc antibodies display a dual role, participating in the host-tissue immunopathogenicity of experimental Chagas disease and favoring the infection by T. cruzi
