Release of the cytosolic tryparedoxin peroxidase into the incubation medium and a different profile of cytosolic and mitochondrial peroxiredoxin expression in H2O2-treated Trypanosoma cruzi tissue culture-derived trypomastigotes

► Release of cytosolic tryparedoxin peroxidase into the H2O2-incubation medium. ► Mitochondrial tryparedoxin peroxidase expression increased with 10 μM H2O2. ► Different peroxiredoxins expression in trypomastigotes upon H2O2-treatment. ► Trypomastigotes integrity was not altered upon H2O2 treatment. ► Trypomastigotes have higher peroxiredoxins expression levels than epimastigotes.
