Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

4.3K
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...

Autoimmune Disorders

395
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.

Functions of Thyroid Hormones

2.6K
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...

科学领域:

  • 神经免疫学 神经免疫学
  • 内分泌学 在内分泌学.
  • 遗传流行病学遗传流行病学

背景情况:

  • 观察性研究表明甲状腺功能与多发性硬化症 (MS) 之间存在联系.
  • 甲状腺功能和MS之间的因果关系尚不清楚.
  • 门德尔随机化 (MR) 可以帮助阐明使用遗传变异的因果关系.

研究的目的:

  • 用MR检测甲状腺功能与MS之间的双向因果关系.
  • 评估甲状腺刺激激素 (TSH),自由甲状腺素 (FT4),甲状腺功能低下症和甲状腺功能过高症对MS风险的因果作用.
  • 检查MS对甲状腺功能参数的潜在因果影响.

主要方法:

  • 双向门德尔随机化 (MR) 分析.
  • 利用来自大型联盟 (ThyroidOmics,FinnGen) 的全基因组关联研究 (GWAS) 数据.
  • 采用反变量加权 (IVW) 作为主要方法,使用包括MR-Egger和异质性/多变性测试在内的灵敏度分析.

主要成果:

  • 在甲状腺刺激激素 (TSH) 和多发性硬化症 (MS) 之间发现了显著的积极因果关系 (IVW:OR=1.202,P=0.013).
  • 没有观察到自由甲状腺素 (FT4),甲状腺功能低下症或甲状腺功能增强症对MS风险的显著因果关系.
  • 反向MR分析显示,MS和研究的甲状腺功能参数之间没有显著的因果关系.

结论:

  • 门德尔的随机化分析支持高TSH水平与MS风险增加之间存在积极的因果关系.
  • 甲状腺功能,特别是TSH,可能在多发性硬化症的发展中起因作用.
  • 进一步的研究是有必要的,以探索连接TSH和MS病变的潜在机制.
