Autoimmune Disorders01:29

Autoimmune Disorders

1.9K
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.

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

817
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease II: Crohn's Disease

1.3K
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...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.2K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

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

600
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...

T Cell Types and Functions01:24

T Cell Types and Functions

2.7K
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...

Summary
This summary is machine-generated.

Monogenic inflammatory diseases involve genetic defects in innate immunity. While biologic therapies targeting cytokines like IL-1 are effective, many autoinflammatory diseases lack genetic diagnoses, necessitating further research into novel pathways.

Area of Science:

  • Immunology
  • Genetics
  • Molecular Biology

Background:

  • Over 15 years, numerous monogenic inflammatory diseases and their genes have been identified.
  • These genes encode proteins regulating inflammation, primarily in innate immune cells.
  • Diagnosis is clinical, supported by genetic testing when possible.

Purpose of the Study:

  • To discuss the characteristics of monogenic inflammatory diseases.
  • To highlight the role of cytokine overproduction in autoinflammatory diseases.
  • To address the diagnostic and therapeutic challenges in autoinflammation.

Main Methods:

  • Literature review of monogenic inflammatory diseases and genetic findings.
  • Analysis of cytokine dysregulation in autoinflammatory conditions.
  • Discussion of current treatment strategies and limitations.

Main Results:

  • Autoinflammatory diseases are characterized by continuous pro-inflammatory mediator release (e.g., IL-1, IL-6, TNF).
  • Biologic agents targeting cytokines, especially IL-1, show significant efficacy in some patients.
  • A subset of patients with autoinflammation lacks identified genetic abnormalities, indicating unmet needs.

Conclusions:

  • Autoinflammatory diseases represent a distinct category from periodic fevers, driven by cytokine overproduction.
  • Targeted biologic therapies offer promising treatment avenues.
  • The identification of novel genetic mutations and pathways is crucial for improving diagnosis and treatment in unexplained autoinflammation.
