Figure 4From: Trypanosoma cruzi mitochondrial swelling and membrane potential collapse as primary evidence of the mode of action of naphthoquinone analoguesTransmission electron microscopy analysis of T. cruzi epimastigotes treated with NQ9. (A-C) This naphthoquinone (2.6 μM) induced morphological alterations in the mitochondrion, including swelling (*) and the formation of membranous structures (black arrows) inside the organelle. Parasites treated with NQ9 also presented atypical cytosolic membranous structures (white arrowheads) and intense cytosolic vacuolization (V). Bars = 500 nm.Back to article page
