Abstract

In the present study, we have produced recombinant paraflagellar rod proteins (PFR) and report their use for successful vaccination of mice against Trypanosoma cruzi. This protection is associated with a highly polarized type 1 cytokine production profile. Additionally, we have analyzed the gene sequence encoding PFR-2 to determine the degree of conservation among seven highly diverse strains of T. cruzi, and found it to be highly conserved. The results presented here indicate that the PFR antigens are highly conserved, and immunization with rPFR-1, PFR-2, or an equimolar mix of the PFR-1, -2, and -3 proteins provides protective immunity against Trypanosoma cruzi.
