T Cell Types and Functions01:24

T Cell Types and Functions

2.1K
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 Selection

14.5K
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 Response01:27

Cytotoxic T Cells-mediated Immune Response

6.4K
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...

Area of Science:

  • Neuroimmunology
  • Autoimmune Diseases
  • Central Nervous System Disorders

Background:

  • Multiple sclerosis (MS) is a primary cause of disability in young adults.
  • MS is characterized by inflammation and demyelination in the central nervous system.
  • The autoimmune etiology of MS is a significant focus of research.

Purpose of the Study:

  • To review the role of cytokines produced by autoreactive CD4 T cells in MS pathogenesis.
  • To elucidate the contribution of specific cytokines to disease development.
  • To inform the potential of cytokine-based therapeutic strategies for MS.

Main Methods:

  • Review of existing literature on MS patients.
  • Analysis of data from animal models of MS.
  • Focus on cytokine production by autoreactive CD4 T cells.

Main Results:

  • Specific cytokines from autoreactive CD4 T cells are implicated in MS pathogenesis.
  • Understanding these cytokine roles is crucial for disease mechanisms.
  • Evidence from both human studies and animal models supports these findings.

Conclusions:

  • Defining the precise roles of cytokines is key to understanding MS.
  • This knowledge will enhance the development of targeted cytokine-based therapies.
  • Future treatments for MS may leverage cytokine modulation for improved outcomes.
