The regulation of the Treg/Th17 balance by mesenchymal stem cells in human systemic lupus erythematosus.

ABSTRACT:

Background and objective

Umbilical cord (UC)-derived mesenchymal stem cells (MSCs) have shown immunoregulation of various immune cells. The aim of this study was to investigate the mechanism of UC MSCs in the regulation of peripheral regulatory T cells (Treg) and T helper 17 (Th17) cells in patients with systemic lupus erythematosus (SLE).

Methods

Thirty patients with active SLE, refractory to conventional therapies, were given UC MSCs infusions. The percentages of peripheral blood CD4+CD25+Foxp3+ regulatory T cells (Treg) and CD3+CD8-IL17A+ Th17 cells and the mean fluorescence intensities (MFI) of Foxp3 and IL-17 were measured at 1 week, 1 month, 3 months, 6 months, and 12 months after MSCs transplantation (MSCT). Serum cytokines, including transforming growth factor beta (
