Trypanosoma cruzi induces genotoxic stress in HeLa cells

Trypanosoma cruzi, the etiologic agent of Chagas' disease, causes massive oxidative stress during infection leading to host cell DNA damage. This fluorescence microscopy image shows intracellular parasites, expressing GFP, multiplying in host cell cytosol. The red foci presented in infected HeLa cell nuclei (stained with DAPI, blue) reveals the phosphorylation of Histone H2Ax, an important signal of genotoxic stress and DNA lesions, caused by the parasite. Florentino et al.
