Constant with these data, we discovered that the administration of T. gondii ESA at early (G5) and intermediate (G10) stages of pregnancy could also bring about the lower of CD4+CD25+Foxp3+ T cells. Having said that, right after the injection of T. gondii ESA in the late pregnancy (G15), the percentage of CD4+CD25+Foxp3+ T cells improved compared with that of your manage group (Figure 2A). The phenomenon could also be observed within the inguinal lymph nodes (LN) and peripheral blood lymphocytes (PBL) (Figure 2B and 2C), suggesting that T. gondii ESA induced worldwide changes of CD4+CD25+Foxp3+ T cells.

We obtained purified CD4+CD25+ T cells in the normal pregnant mice and the mice with T. gondii ESA-injection at G5, G10 and G15, [http://www.ncbi.nlm.nih.gov/pubmed/1315463 1315463] respectively. The decreased suppressive ability of CD4+CD25+ T cells was observed in mice together with the ESA-injection at G5 and G10. Nevertheless, the inhibitory capacity of the CD4+CD25+ T cells was enhanced right after the injection of T. gondii ESA at G15 (Figure 2D). As a result of the capacity of CD4+CD25+ Treg cells controlling potentially detrimental IFN-c reactions in the course of pregnancy [28], we detected the serum level of IFN-c immediately after the injection of T. gondii ESA. We discovered that the serum amount of IFN-c was as much as 448.three pg/ml at G5 ip, suggesting that the activity of CD4+CD25+ Tregs on the suppression of IFN-c production was impaired (Figure 2E). As anticipated, in all groups of mice, the serum IL-4 levels had been not certainly impacted (Figure 2F).
