520 |a Regulatory T cells (Tregs) are known to suppress alloimmune responses during pregnancy and post organ transplantation. We demonstrate that a distinct subset of FoxP3(+)DR(+)-Tregs among the total CD4(+)CD127(low+/-)CD25(+)-Treg cell pool is critically involved in preterm labor induction and kidney transplant rejection as well. Compared to healthy pregnancies and non-rejecting kidney recipients, we found that the percentage of the FoxP3(+)DR(+)-Treg subset was not reduced, but that the level of HLA-DR expression of such Tregs was strongly diminished in preterm laboring women and in patients with acute renal allograft rejection. In addition, both patient collectives showed a significantly reduced suppressive activity of their circulating CD4(+)CD127(low+/-)CD25(+)-Treg cell pool. Our findings propose that the FoxP3(+)DR(+)-Treg subset may be decisively responsible for the suppressive activity of the total CD4(+)CD127(low+/-)CD25(+)-Treg cell pool and that the immunologic mechanisms leading to preterm labor necessitating preterm delivery may be similar to those leading to allograft rejection after transplantation
