Regulation of oxidative stress and apoptosis in Trypanosoma cruzi infected cells

点击翻译按钮获取中文摘要

In Trypanosoma cuzi infected cells, the production of reactive oxygen species including nitric oxide (NO) was increased and inducible nitric oxide synthase (iNOS) gene was up-regulated. The inhibition of apoptosis in infected cells was reduced by the addition of NOS inhibitors. Furthermore, cellular FLICE-like inhibitory protein (c-FLIP), an apoptosis inhibitory protein, was nitrosylated in T. cruzi infected cells.
