T Cell Types and Functions01:24

T Cell Types and Functions

3.2K
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

2.3K
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.

Inflammatory Response01:28

Inflammatory Response

12.4K
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 III: Crohn's Disease

22
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

14
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Inflammation: Introduction

46
Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...

Area of Science:

  • Biochemistry
  • Immunology
  • Molecular Biology

Background:

  • Disintegrin and metalloproteinase 17 (ADAM17), also known as tumor necrosis factor-alpha converting enzyme (TACE), is a protease with sheddase activity.
  • ADAM17 cleaves various non-matrix substrates, including cytokines, cytokine receptors, ErbB ligands, and adhesion proteins, impacting cellular signaling and inflammation.
  • Dysregulated metalloproteinase activity is a hallmark of inflammatory autoimmune diseases.

Purpose of the Study:

  • To elucidate the molecular mechanisms of ADAM17 in diseased conditions.
  • To investigate the role of ADAM17 in regulating inflammation and autoimmunity.
  • To explore how ADAM17 influences the progression of inflammatory processes in autoimmune diseases.

Main Methods:

  • Review of recent experimental model systems.
  • Analysis of studies investigating ADAM17-dependent cleavage of substrates in inflammatory diseases.
  • Exploration of research on ADAM17's role in modulating inflammation and autoimmunity.

Main Results:

  • ADAM17 modifies numerous non-matrix substrates crucial for inflammatory signaling.
  • Experimental models are used to understand ADAM17's role in regulating signaling pathways and tissue interactions.
  • Evidence suggests ADAM17 significantly influences the outcome of inflammation in autoimmune conditions.

  • ADAM17 plays a critical role in the pathogenesis of inflammatory autoimmune diseases.
  • Further research into ADAM17's regulatory functions is essential for understanding and potentially treating autoimmune disorders.
  • ADAM17 acts as a key modulator of inflammation in the context of autoimmunity.
