These authors also found elevated levels of IL-10 in the lungs at 1-2 weeks’ post-infection, we did not find elevated IL-10 concentrations in serum of untreated T. vitulorum-rat model throughout this experiment, indicating that the production of this cytokine occurred only after stem cell therapy and this elevation was attributed to the immunomodulatory effect of the transplanted BMMSCs. This evidence concerns the gene IL10 and infection.
