Autoimmune Disorders01:29

Autoimmune Disorders

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 Bowel Disease III: Crohn's Disease01:25

Inflammatory Bowel Disease III: Crohn's Disease

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...

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

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 (Humira),...

Inflammatory Bowel Disease II: Crohn's Disease

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 transmural...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
Inflammatory Bowel Disease IV: Pharmacological Management01:29

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Summary

Auto-inflammation, involving innate immunity, is a key concept in understanding recurrent inflammatory diseases. This research highlights its role in classifying inflammatory disorders, distinguishing them from autoimmune conditions.

Area of Science:

  • Immunology
  • Genetics
  • Rheumatology

Background:

  • Auto-inflammation defines mendelian disorders with recurrent inflammatory symptoms, including hereditary fevers.
  • Mutations in the CIAS1/PYPPAF1/NALP3/NLRP gene, encoding cryopyrin, are central to inflammasome regulation of interleukin-1.
  • This understanding has significantly advanced the study of innate immunity.

Purpose of the Study:

  • To explore the concept of auto-inflammation in classifying inflammatory disorders.
  • To differentiate auto-inflammatory conditions from autoimmune diseases.
  • To integrate genetic and innate immunity components into disease nosology.

Main Methods:

  • Literature review on auto-inflammatory and mendelian inflammatory disorders.
  • Analysis of the role of cryopyrin and the inflammasome in innate immunity.
  • Conceptual framework development for disease classification.

Main Results:

  • Auto-inflammation encompasses hereditary fevers and other inflammatory mendelian disorders.
  • Cryopyrin mutations are crucial in inflammasome-mediated interleukin-1 production.
  • Innate immunity mechanisms are pivotal in auto-inflammatory conditions.

Conclusions:

  • Innate immunity mechanisms necessitate a re-evaluation of inflammatory disorder classification.
  • A proposed classification distinguishes diseases based on predominant auto-inflammation versus auto-immunity.
  • This framework offers a new perspective on the spectrum of inflammatory diseases.
