Phenotypic characterization of regulatory T cells populations in maternal blood, cord blood and placenta from diabetic mothers.

Changes in regulatory T cells (Treg) in peripheral blood are associated with a number of pathologies, including diabetes. However, the immunological responses of pregnant diabetic women remain scarcely known, and the effects of Treg cells in these patients have yet to be investigated. The present study characterized the expression of regulatory T cells in the maternal blood, cord blood and placenta of diabetic pregnant women.
