Regulatory T cells (Treg) are vital for controlling immune responses to self-antigens and preventing autoimmune diseases. This review explores human Treg function and their role in autoimmunity.
Area of Science:
- Immunology
- Autoimmunity
- Cell Biology
Background:
- CD4+CD25+ regulatory T cells (Treg) are crucial for immune homeostasis.
- Treg deficiency is linked to human autoimmune disorders.
- The precise mechanisms of Treg action are not fully understood.
Purpose of the Study:
- To review the characteristics of human natural Treg.
- To elucidate the functional mechanisms of Treg.
- To examine the involvement of Treg in autoimmune diseases.
Main Methods:
- Literature review of murine and human Treg studies.
- Analysis of Treg phenotype and function.
- Synthesis of current knowledge on Treg in autoimmunity.
Main Results:
- Human natural Treg exhibit distinct phenotypic markers.
- Treg employ various mechanisms to suppress immune responses.
- Dysregulation of Treg contributes to the pathogenesis of autoimmune diseases.
Conclusions:
- Understanding human Treg function is key to addressing autoimmune diseases.
- Further research into Treg mechanisms may reveal therapeutic targets.
- Treg play a pivotal role in maintaining self-tolerance.
