T Cell Types and Functions

T 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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

T Cell Activation and Clonal Selection

T 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.
Naive T cells that have not yet encountered an antigen express two primary CD...

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

TGF - β Signaling Pathway

TGF - β Signaling Pathway

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 are of three kinds RI, RII, and RIII. The RI...

Inflammatory Response

Inflammatory Response

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,...

Summary

Regulatory T cells (Treg) suppress immune responses and maintain self-tolerance. This review integrates evidence on Treg cell suppressive pathways, including direct killing, cytokine inhibition, and immunomodulatory cytokine secretion.

Area of Science:

Immunology
Cell Biology

Background:

Regulatory T cells (Treg) are crucial for immune tolerance and preventing autoimmunity.
Treg cells modulate immune responses by suppressing the activity of other immune cells.

Purpose of the Study:

To integrate current experimental evidence on Treg cell suppressive mechanisms.
To delineate the major pathways utilized by Treg cells to suppress immune reactions.

Main Methods:

Review and integration of existing experimental data on Treg cell function.
Analysis of Treg cell-mediated suppression mechanisms in various inflammatory contexts.

Main Results:

Treg cells employ three primary mechanisms: direct cytotoxic cell killing, inhibition of cytotoxic cell cytokine production (e.g., IL-2), and secretion of immunomodulatory cytokines (e.g., TGF-beta, IL-10).
The contribution of these mechanisms varies with inflammatory conditions and Treg cell subsets.
Mechanistic complexity arises from diverse Treg cell functions across different immune response stages.

Conclusions:

Treg cells utilize a complex and adaptable set of suppressive pathways to maintain immune homeostasis.
Understanding these pathways is key to developing therapies for autoimmune diseases and transplantation.
