T Cell Types and Functions01:24

T Cell Types and Functions

3.1K
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

17.0K
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...

B Cell Activation and Differentiation01:24

B Cell Activation and Differentiation

17.8K
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

10.8K
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...

Master Transcription Regulators02:23

Master Transcription Regulators

8.0K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

7.8K
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...

Summary

Regulatory T cells expressing the transcription factor Foxp3 are crucial for suppressing immune-mediated inflammation. These cells help prevent autoimmune diseases, allergies, and cancer by regulating inflammatory responses to pathogens and self-antigens.

Area of Science:

  • Immunology
  • Molecular Biology
  • Cell Biology

Background:

  • Vertebrate immune systems defend against pathogens while limiting inflammation-induced tissue damage.
  • Dysregulated immune responses to self, dietary, or microbial antigens can cause inflammatory disorders like autoimmunity, metabolic syndrome, allergies, and cancer.

Purpose of the Study:

  • To highlight the critical role of regulatory T cells (Tregs) in immune-mediated inflammation.
  • To emphasize the function of the transcription factor Foxp3 in Treg-mediated suppression.

Main Methods:

  • Review of existing literature on immune regulation and inflammatory disorders.
  • Focus on the molecular mechanisms of regulatory T cell function.

Main Results:

  • Regulatory T cells (Tregs) expressing Foxp3 are essential for suppressing inflammatory responses.
  • Foxp3+ Tregs act as a vital negative regulatory mechanism in various biological contexts.
