| Abstract | |
Adipose-derived mesenchymal stem cells (ADMSCs) display immunosuppressive properties representing a promising therapeutic approach for several autoimmune diseases. The aim of this study was to investigate the immune regulatory properties of allogeneic ADMSCs therapy in T cell-mediated experimental autoimmune diabetes in NOD mice. Diabetic NOD mice (blood glucose > 240 mg/dl) were treated or not with ADMSC at days 0, 7 and 14 and blood glucose was monitored once a week for 12 weeks after treatment. ADMSC reversed the hyperglycemia levels of early onset T1D in 78% of diabetic-treated mice for 8 weeks after treatment. ADMSC therapy efficiently ameliorates T1D pathogenesis in diabetic NOD mice by attenuating the Th1 immune response concomitantly with the expansion of Treg cells, thereby contributing to maintenance of functional -cells. This study may thus provide a new therapeutic perspective for the development of ADMSC-based cellular therapies for T1D. (AU) | |
