Abstract:

BACKGROUND: Autoreactive T cells are a group of specialized cells that exert a peripheral immunosuppressive effect through certain mechanisms ensuring self-tolerance within the adaptive immune system. The discovery of the latest surface markers for natural CD4+CD25+ regulatory T cells has re-emphasized the concept of peripheral regulation or suppression of T cells. Several groups have begun to investigate the role of regulatory T cells in animal models of allogeneic hematopoietic stem cell transplantation.

OBJECTIVE: To review the recent results regarding protection from graft-versus-host disease by adoptively transferred CD4+ CD25+ regulatory T cells in mice and to discuss the latest findings from clinical studies on hematopoietic stem cell transplantation.
METHODS: We retrieved CNKI, PubMed and Medline databases for articles concerning CD4+CD25+ regulatory T cells and graft-versus-host disease published from 2000 to 2015. According to inclusion and exclusion criteria, 46 papers were included in result analysis.

RESULTS AND CONCLUSION: CD4+CD25+ regulatory T cells expressing the transcriptional repressor FOXP3 mediate immunoregulatory functions and are critical for the prevention of autoimmune diseases. As peripheral tolerance induction is a prerequisite for successful allogeneic hematopoietic stem cell transplantation, the role of CD4+CD25+ regulatory T cells in transplantation models and clinical trials is now under investigation in many laboratories. CD4+CD25+ regulatory T cells play an important role in the development of graft-versus-host disease after allogeneic hematopoietic stem cell transplantation. CD4+CD25+ regulatory T cells not only effectively prevent and treat graft-versus-host disease but also retain graft-versus-leukemia effect.
