Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

9.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Autoimmune Disorders

2.2K
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.

The Thyroid Gland01:23

The Thyroid Gland

8.9K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Redox Titration: Iodimetry and Iodometry01:23

Redox Titration: Iodimetry and Iodometry

7.2K
Iodometry and iodimetry are analytical methods used to determine the concentration of oxidizing or reducing agents using iodine. In iodometric titrations, the oxidizing analyte solution is usually acidified and treated with an excess of iodide ions, which generates an equivalent amount of iodine in equilibrium with triiodide. The released iodine is subsequently titrated directly against a standardized reducing agent. As the dilute iodine color becomes pale yellow, a few drops of freshly...

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

704
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...

  • Endocrinology
  • Nutritional Science
  • Immunology

Background:

  • Selenium and iodine are vital micronutrients for thyroid hormone synthesis and function.
  • Selenium, as selenocysteine, is integral to antioxidant enzymes and iodothyronine deiodinases.
  • Iodine deficiency leads to disorders such as goiter and hypothyroidism.

Purpose of the Study:

  • To review the critical roles of selenium and iodine in the pathogenesis of autoimmune thyroid diseases.
  • To elucidate the mechanisms by which these micronutrients influence thyroid autoimmunity.

Main Methods:

  • Literature review of existing studies on selenium, iodine, and autoimmune thyroiditis.
  • Analysis of biochemical and clinical data linking micronutrient status to thyroid autoimmunity.

Main Results:

  • Selenium and iodine are implicated in the development and progression of autoimmune thyroiditis.
  • Specific enzymes utilizing selenium are key in thyroid hormone metabolism and protection.
  • Iodine's direct role as a component of thyroid hormones highlights its essentiality.

Conclusions:

  • Selenium and iodine play significant roles in maintaining thyroid health and modulating autoimmune thyroid disease activity.
  • Understanding these roles may offer new therapeutic strategies for autoimmune thyroid conditions.
