Autoimmune Disorders01:29

Autoimmune Disorders

2.0K
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-TNF

658
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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

2.1K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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

604
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...

Diabetes Mellitus: Overview and Type I Subtype

5.7K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Myasthenia Gravis: Overview and Treatment

3.1K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Area of Science:

  • Immunology
  • Endocrinology
  • Neurology

Background:

  • Autoimmunity is proposed as a Type I interferon (IFN) immunodeficiency syndrome.
  • Clinical trials investigated the safety and efficacy of ingested IFN-alpha in autoimmune diseases.

Purpose of the Study:

  • To evaluate the potential of ingested IFN-alpha as a treatment for autoimmune conditions.
  • To assess the safety and efficacy of oral IFN-alpha in Phase I and II clinical trials.

Main Methods:

  • Phase I trials in type 1 diabetes, rheumatoid arthritis (RA), and multiple sclerosis (MS).
  • Phase II randomized, placebo-controlled, double-blind trial in MS.
  • Assessed beta cell function, cytokine secretion (IL-1, IL-2, IFN-gamma, TNF-alpha), and MRI gadolinium enhancements.

Main Results:

  • Ingested IFN-alpha preserved beta cell function in type 1 diabetes.
  • Reduced pro-inflammatory cytokine secretion (IL-1, IL-2, IFN-gamma, TNF-alpha) in RA and MS.
  • Significantly decreased gadolinium enhancements in MS patients.
  • Demonstrated a favorable safety profile with no observed toxicity.

Conclusions:
