T Cell Types and Functions01:24

T Cell Types and Functions

2.0K
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 Selection01:22

T Cell Activation and Clonal Selection

14.4K
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...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

10.3K
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...

Area of Science:

  • Immunology
  • Cell Biology

Background:

  • Foxp3-expressing CD4+ regulatory T (Treg) cells are crucial for preventing autoimmunity and maintaining immune homeostasis.
  • Treg cells also pose a significant challenge to developing effective anti-tumor immune responses.

Purpose of the Study:

  • To review current knowledge on the signals coordinating Treg cell differentiation.
  • To discuss the antigen-presenting cells involved in Treg cell selection.
  • To examine the nature of endogenous Treg cell ligands.

Main Methods:

  • Review of existing scientific literature and studies, primarily focusing on mouse models.
  • Analysis of signals, cell types, and molecular interactions governing Treg cell development.

Main Results:

  • Treg cell differentiation is orchestrated by specific signals and antigen-presenting cell interactions.
  • Endogenous ligands play a role in Treg cell function and selection.
  • Recent advances have shed light on Treg cell biology.

Conclusions:

  • A comprehensive understanding of Treg cell mechanisms is essential for both health and disease management.
