Resumen

The immunological properties of the Trypanosoma cruzi paraflagellar rod proteins (PFR2 and PFR3) administered alone as well as fused to HSP70 have been analyzed in mice in the context of genetic immunization. The immunization of mice with the DNA vectors containing the PFRs gene or PFRs-HSP70 fused genes induced high level of IgG2a anti-PFRs. However, only the immunization with the PFR2-HSP70 fused genes triggers in spleen cells a statistically significant enhancement of expression of IL-12 and IFN- and a decrease in the percentage of cells expressing IL-4. Likewise, the PFR2-HSP70 molecule elicits a statistically significant activation of PFR2 antigen specific CTLs. Immunization with the PFR2-HSP70 chimeric gene provided a protective response against a T. cruzi experimental infection.
