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...

Autoimmune Disorders01:29

Autoimmune Disorders

2.1K
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.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

696
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Inflammatory Response01:28

Inflammatory Response

18.0K
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,...

Inflammatory Bowel Disease II: Crohn's Disease

1.4K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions01:29

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

116
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

Area of Science:

  • Immunology
  • Innate Immunity
  • T cell Biology

Background:

  • Autoinflammatory diseases involve inappropriate innate immune activation without infection.
  • Gamma delta (γδ) T cells bridge innate immunity and adaptive functions.
  • While neutrophils and macrophages are known drivers, γδ T cells are increasingly recognized as key players.

Purpose of the Study:

  • To review the role of γδ T cells in monogenic and multifactorial autoinflammatory diseases.
  • To highlight how γδ T cells link innate immune activation to inflammatory pathology.
  • To explore the potential of targeting γδ T cells for therapeutic strategies.

Main Methods:

  • Review of existing evidence on γδ T cell involvement in various autoinflammatory conditions.
  • Analysis of studies examining γδ T cell frequencies, activation, and cytokine profiles.
  • Inclusion of transcriptomic and tissue-based analyses of γδ T cells at inflammatory sites.

Main Results:

  • γδ T cells show altered frequencies, activation states, and cytokine polarization in diseases like familial Mediterranean fever, gout, and Behçet's disease.
  • In inflammasome-driven diseases, γδ T cells often skew towards Interleukin-17 (IL-17) production, enhancing inflammation.
  • γδ T cells accumulate and specialize at sites of sterile inflammation, acting as amplifiers.

Conclusions:

  • γδ T cells are central amplifiers and modulators of inappropriate innate immune activation in autoinflammatory diseases.
  • Their altered function contributes to tissue-specific inflammatory pathology.
  • Understanding γδ T cell subset regulation may lead to novel therapeutic approaches.
