Summary
Naturally occurring regulatory T cells (nTreg) prevent autoimmunity but are scarce. TGF-β1 can induce regulatory T cells (iTreg) in vitro, offering a potential therapeutic strategy for autoimmune diseases.
Area of Science:
- Immunology
- Autoimmunity
- Cell Therapy
Background:
- Peripheral tolerance is crucial for preventing autoimmunity by suppressing self-reactive T cells.
- Naturally occurring thymic-derived regulatory T cells (nTreg) are key mediators of peripheral tolerance.
- Therapeutic application of nTreg is limited by their scarcity.
Purpose of the Study:
- To discuss the generation and function of TGF-β1-induced regulatory T cells (iTreg).
- To explore the potential of iTreg as a cell therapy for autoimmune diseases.
- To review current challenges and drawbacks in the therapeutic use of iTreg.
Main Methods:
- Discussion of in vitro induction of iTreg from conventional CD4(+) T cells using TGF-β1.
- Review of murine and human iTreg generation and function.
- Analysis of potential therapeutic applications and limitations.
Main Results:
- TGF-β1 is essential for nTreg generation and function.
- TGF-β1 can induce regulatory T cells (iTreg) in vitro from conventional T cells.
- iTreg represent a promising avenue for cell-based immunotherapy.
Conclusions:
- TGF-β1-induced regulatory T cells (iTreg) offer a scalable alternative to nTreg for treating autoimmune conditions.
- Further research is needed to overcome challenges in the clinical application of iTreg.
- iTreg hold significant therapeutic potential for dampening autoimmune responses.

10.3K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

01:24T Cell Types and Functions
2.0K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
