- Regulatory T-cells (Tregs) are a subset of T-cells that play a crucial role in maintaining immune homeostasis and preventing excessive immune responses.
- They are characterized by the expression of a transcription factor called Foxp3, which is essential for their development and function.
- Tregs can be divided into two main subsets: natural Tregs (nTregs) and induced Tregs (iTregs).
- nTregs develop in the thymus during T-cell maturation, while iTregs can be generated from conventional T-cells in the periphery under certain conditions.
- Tregs exert their suppressive function through various mechanisms, including the secretion of immunosuppressive cytokines like IL-10 and TGF-beta, direct cell-to-cell contact, and metabolic disruption of effector T-cells.
- They are involved in maintaining self-tolerance, preventing autoimmune diseases, and controlling excessive immune responses during infections and inflammation.
- Dysregulation of Tregs has been implicated in various diseases, including autoimmune disorders, allergies, and cancer.
- Therapeutic strategies targeting Tregs are being explored for the treatment of autoimmune diseases and cancer, with the aim of enhancing or suppressing their function depending on the context.
