چکیده انگلیسی
We reported recently a higher frequency of Th1 cytokine-producing T cells specific against paternal antigens in abortion-prone mice compared to normal pregnant mice. Since Th2 cells were shown to be not essential for normal pregnancy; alloreactive Th1 cells must be differently regulated. In this context, T regulatory cells (Treg) were proposed to play an essential role. Normal pregnant mice show an expansion of CD4+CD25+ and IL-10+ Treg cells at the periphery compared to non-pregnant animals. Further, we reported significantly lower frequencies of Treg in abortion-prone mice. Interestingly, CD4+CD25+ Treg cells from normal pregnant mice were able to prevent fetal rejection. Accordingly, down-regulated levels of Treg were also reported during human miscarriage. The putative mechanisms involved in Treg-induced tolerance in mice and humans are discussed in this review.
