- Plasmid DNA immunization with Trypanosoma cruzi genes induces cardiac and clinical protection against Chagas disease in the canine model.
- Rodríguez-Morales O, Pérez-Leyva MM, Ballinas-Verdugo MA, Carrillo-Sánchez SC, Rosales-Encina JL, Alejandre-Aguilar R, Reyes PA, Arce-Fonseca M.AbstractABSTRACT: The only existing preventive measure against American trypanosomosis, or Chagas disease, is the control of the transmitting insect, which has only been effective in a few South American regions. Currently, there is no vaccine available to prevent this disease. Here, we present the clinical and cardiac levels of protection induced by expression to Trypanosoma cruzi genes encoding the TcSP and TcSSP4 proteins in the canine model. Physical examination, diagnostic chagasic serology, and serial electrocardiograms were performed before and after immunization, as well as after experimental infection. We found that immunization with recombinant plasmids prevented hyperthermia in the acute phase of experimental infection and produced lymphadenomegaly as an immunological response against the parasite and additionally prevented heart rate elevation (tachycardia) in the acute and/or chronic stages of infection. Immunization with T. cruzi genes encoding the TcSP and TcSSP4 antigens diminished the quality and quantity of the electrocardiographic abnormalities, thereby avoiding progression to more severe developments such as right bundle branch block or ventricular premature complexes in a greater number of dogs.

- … This study tested the hypothesis that the maximum slope of the Cai decline (-(dCai/dt)max) corresponds to the timing of anodal dip on the strength-interval curve and the initiation of repetitive responses and ventricular fibrillation (VF) after a premature stimulus (S2). … The interval between S2 and the first non-driven beat was coincidental with the time of -(dCai/dt)max. Conclusions: Larger Cai transient and INCX activation induced by anodal stimulation produces anodal supernormality. …
