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...

Autoimmune Disorders

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

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...

Differentiation of Common Myeloid Progenitor Cells

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Background:

Autoimmune diseases involve a loss of self-tolerance, causing inflammation and organ damage.
Th1 and Th17 cells were previously thought to be the main drivers of T-cell pathology.
A distinct CD4+ T helper cell subset producing GM-CSF is now recognized as a critical pathogenic factor.

Purpose of the Study:

To review the current understanding of GM-CSF-producing T helper cells in autoimmunity.
To evaluate their classification, molecular identity, and differentiation pathways.
To explore their roles in various autoimmune diseases and their therapeutic potential.

Main Methods:

Literature review synthesizing current research on GM-CSF-producing T helper cells.
Critical evaluation of cell classification, molecular markers, and signaling pathways.
Analysis of their pathogenic roles in specific autoimmune diseases.

Main Results:

GM-CSF-producing Th cells are non-redundant drivers of autoimmune pathology across multiple diseases.
These cells amplify inflammation by activating myeloid cells and creating feedback loops.
Significant heterogeneity and plasticity exist within this T cell subset.

Conclusions:

GM-CSF-producing T helper cells are central orchestrators of autoimmune disease pathogenesis.
Understanding their heterogeneity and regulatory networks is crucial.
Targeting the GM-CSF axis presents significant translational potential for novel therapies and biomarkers.
