The Thyroid Gland01:23

The Thyroid Gland

6.8K
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

5.0K
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...

Synthesis and Regulation of Thyroid Hormones

7.3K
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...

Co-activators and Co-repressors

8.4K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Area of Science:

  • Endocrinology
  • Immunology
  • Hematology

Background:

  • Autoimmune mechanisms can cause thrombocytopaenia (low platelet count).
  • Immune thrombocytopaenia is frequently associated with autoimmune thyroid disease.

Observation:

  • A teenager with a history of thrombocytopaenia presented with fatigue.
  • Laboratory tests revealed thyroid autoantibodies.
  • Further investigation identified antibodies against platelet glycoprotein IIbIIIa.

Findings:

  • The case demonstrates a link between thyroid autoimmunity and platelet autoimmunity.
  • Co-existence of thrombocytopaenia and thyroiditis was investigated.

Implications:

  • This case highlights the potential overlap between thyroid and platelet autoimmune conditions.
  • Understanding these associations can improve diagnosis and management of complex autoimmune presentations.
