Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

9.4K
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

9.1K
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...

Functions of Thyroid Hormones

7.1K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Renal Drug Excretion: Tubular Secretion01:28

Renal Drug Excretion: Tubular Secretion

1.2K
Active tubular secretion is a robust, energy-demanding process that utilizes carrier systems to transport drugs into renal tubules. The active renal secretion systems include the organic anion transporter (OAT) for weak acids and the organic cation transporter (OCT) for weak bases. Structurally similar drugs can compete for the same transporter, potentially leading to drug accumulation and toxicity. However, this principle can be exploited therapeutically. One example is probenecid (Probalan),...

Carrier-Mediated Transport01:06

Carrier-Mediated Transport

1.6K
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

The Parathyroid Glands00:59

The Parathyroid Glands

6.2K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Area of Science:

  • Endocrinology
  • Cell Biology
  • Molecular Biology

Background:

  • Thyroid follicular epithelial cells synthesize thyroxine (T4) and triiodothyronine (T3).
  • Iodide transport is essential for thyroid hormone production.
  • The mechanism of iodide uptake from the blood is known, but apical iodide efflux remains unclear.

Purpose of the Study:

  • To explore the mechanisms of iodide transport across the apical membrane of thyroid follicular cells.
  • To identify potential molecular players involved in apical iodide efflux.

Main Methods:

  • Review of physiological properties of anion transport proteins.
  • Analysis of molecularly characterized transporters.

Main Results:

  • Several anion transport proteins are identified as potential contributors to apical iodide efflux.
  • The physiological roles of these transporters in iodide transport are considered.

Conclusions:

  • Understanding apical iodide efflux is critical for comprehending thyroid hormone synthesis.
  • Anion transport proteins are key candidates for mediating iodide transport across the apical membrane.
