Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

4.8K
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...

The Thyroid Gland01:23

The Thyroid Gland

4.1K
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...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

209
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

7.3K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.9K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Area of Science:

  • Immunology
  • Endocrinology
  • Cell Biology

Background:

  • Graves' disease (GD) is an autoimmune disorder targeting the thyroid stimulating hormone receptor (TSHR).
  • Thyroid eye disease (TED), a common manifestation of GD, involves orbital inflammation and tissue remodeling.
  • Sphingolipids, including the acid sphingomyelinase/ceramide system and sphingosine 1-phosphate, are implicated in TED pathogenesis.

Purpose of the Study:

  • To discuss the role of sphingolipid biophysical properties in cell signaling within TED.
  • To review the function of the acid sphingomyelinase/ceramide system in autoimmune diseases and T lymphocytes.
  • To propose novel hypotheses for TED pathogenesis and potential therapeutic targets.

Main Methods:

  • Literature review and synthesis of existing research on sphingolipids and TED.
  • Analysis of sphingolipid involvement in autoimmune responses and T cell function.
  • Exploration of biophysical properties of sphingolipids in cellular signaling.

Main Results:

  • Sphingolipids significantly influence cell signaling pathways relevant to TED.
  • The acid sphingomyelinase/ceramide system plays a role in autoimmune conditions and T lymphocyte activity.
  • Understanding sphingolipid biophysics may reveal new insights into TED.

Conclusions:

  • Sphingolipids are critical mediators in the pathogenesis of thyroid eye disease.
  • The acid sphingomyelinase/ceramide system presents a potential therapeutic target for autoimmune disorders.
  • Further research into sphingolipid biophysics could lead to novel treatments for Graves' disease and TED.
