| Research Abstract |
To find a new strategy to treat a chronic Chagas adult patient, we tried to establish a chronic infection model with mouse and luciferase gene transfected Y strain of Trypanosoma cruzi and successfully obtain a protocol to observe the chronic status using whole body imaging system. Then we prepared the DNA vaccine using previously reported three candidate genes namely TcG1, TcG2 and Tcg4 and our recently established pVAX 200DEST nano-particle adjuvant to observe that effect on the elimination of chronically infected parasites. The evaluation of the vaccines has not yet finished but the vaccination could provoke substantial immunological effect by B and T cell levels.
