ABSTRACT
The repair strategy after organs injuries has always been a hot topic in the field of regenerative medicine. Traditional injury repair measures mainly promote tissue repair through mesenchymal stem cells and various growth factors, but these strategies have been constrained in the aspects of security and economy. Hence, there is an urgent need to find new ways to promote tissue repair and regeneration. There have been a lot of evidences showing that the immune system plays an important role in tissue regeneration and repair. In recent years, more and more studies have been done on adaptive immunity in tissue repair, especially the regulatory T cells. Some evidences indicate that regulatory T cells participate in damage tissue repair and regeneration of multiple organs and tissue. This review briefly introduces the new advances in the repair effects and regulatory mechanism of regulatory T cells in different organ injuries, in order to provide new ideas for designing advanced repair materials with good immunoregulatory functions.
