Summary
Foxp3(+) regulatory T (Treg) cells, known for suppressing immune responses, can also exhibit effector functions. This dual capacity is crucial for understanding immune responses and developing Treg-based therapies.
Area of Science:
- Immunology
- Cellular Biology
Background:
- Foxp3(+) regulatory T (Treg) cells are critical for preventing autoimmunity and maintaining immune homeostasis.
- Their primary function is immune suppression, making them a therapeutic target.
Purpose of the Study:
- To explore the evidence for Treg cells exhibiting non-suppressive functions.
- To understand the drivers and implications of these dual roles in immune responses.
- To assess the significance for Treg-based therapeutic strategies.
Main Methods:
- Review of existing scientific literature and evidence.
- Analysis of studies investigating Treg cell transcription factors and functions.
Main Results:
- Growing evidence indicates that Treg cells can express transcription factors typically associated with T effector cells.
- These findings challenge the notion of Treg cells solely performing suppressive roles.
Conclusions:
- Treg cells possess a broader functional repertoire than previously understood, including effector functions.
- Understanding this plasticity is vital for advancing immunotherapies and treating autoimmune diseases.

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.

19.2K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.
