Summary
Induced regulatory T (iTreg) cells, generated in vitro, are crucial for maintaining immune tolerance. This review explores their induction, function, and therapeutic potential compared to natural Treg cells.
Area of Science:
- Immunology
- Cellular Biology
Background:
- CD4(+) CD25(+) Foxp3(+) regulatory T (Treg) cells are vital for immune homeostasis.
- Two main subsets exist: thymus-derived natural Treg (nTreg) cells and peripherally induced Treg (iTreg) cells.
- Both nTreg and iTreg cells are essential for immunological tolerance.
Purpose of the Study:
- This review focuses on induced Treg (iTreg) cells, comparing them with natural Treg (nTreg) cells.
- It examines the molecular mechanisms, transcriptional profiles, and suppressive functions of iTreg cells.
- The review also discusses iTreg cell generation, stability, and therapeutic applications in inflammatory conditions.
Main Methods:
- Comparative analysis of nTreg and iTreg cell subsets.
- Review of molecular mechanisms for iTreg cell induction in vivo and in vitro.
- Examination of transcriptional landscapes and suppressive mechanisms.
- Comparison of T cell receptor repertoires.
- Discussion of clinical relevance in inflammatory diseases.
Main Results:
- iTreg cells can be generated in vitro and can restore tolerance when Treg cells are deficient.
- Distinct molecular and transcriptional profiles exist between nTreg and iTreg cells.
- Both subsets employ various suppressive mechanisms to maintain immune tolerance.
- iTreg cells show potential for therapeutic intervention in inflammatory conditions.
Conclusions:
- iTreg cells are a distinct and functionally important subset of regulatory T cells.
- Understanding iTreg cell biology is key to developing novel immunotherapies.
- Further research into iTreg cell stability and application is warranted.

01:24T Cell Types and Functions
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.

01:22T Cell Activation and Clonal Selection
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
