Summary
Regulatory T cells (Tregs) maintain immune tolerance and perform unique functions in tissues. Recent research reveals novel mechanisms of Treg activity, focusing on fork-head box P3 (Foxp3) and tissue-specific Treg roles.
Area of Science:
- Immunology
- Cell Biology
Background:
- Regulatory T cells (Tregs) are crucial for immune tolerance.
- Emerging evidence highlights diverse roles and phenotypes of Tregs in non-lymphoid tissues.
Purpose of the Study:
- To review novel mechanisms of Treg activity.
- To interpret the function of fork-head box P3 (Foxp3) in Treg development and function.
- To discuss the diversity and functions of tissue-resident Tregs.
Main Methods:
- Literature review and synthesis of recent research findings on Tregs.
- Focus on soluble mediators, functional proteins, and inhibitory receptors involved in Treg function.
Main Results:
- Tregs exhibit multifaceted functions beyond immune tolerance.
- Foxp3 is identified as a master regulator for Treg development and function.
- Tissue-resident Tregs possess unique phenotypes and distinct activities.
Conclusions:
- Tregs have complex and varied roles in immunity and tissue homeostasis.
- Understanding novel Treg mechanisms is essential for advancing immunology.
- Further research into tissue-specific Tregs promises new therapeutic insights.

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.

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.
