- 数据来源于大规模的全基因组关联研究,包括英国生物银行和FinnGen.
- 标准的MR方法 (反变量加权,MR-Egger,加权中位数) 被采用,以及敏感性分析来评估变性和异质性.
主要成果:
- 基因预测血清25(OH) D水平的增加与自身免疫性甲状腺炎 (AIT) 的风险降低显著相关 (OR 0.499,p=0.012).
- 血清25(OH) D水平与自身免疫性甲状腺功能障碍 (AIH) (OR 0.935,p=0.654) 或格雷夫斯病 (GD) (OR 0.813,p=0.100) 的风险之间没有发现显著的因果关系.
- 灵敏度分析证实了研究结果的可靠性,没有证据表明有显著的水平类或异质性.
结论:
- 血清25(OH) D水平升高与自身免疫性甲状腺炎 (AIT) 风险降低有关.
- 维生素D状况似乎对自身免疫性甲状腺功能增强症 (AIH) 或格雷夫斯病 (GD) 的风险没有因果关系.
- 这些发现表明,维持足够的维生素D水平可能是预防和管理AIT的有益策略.

Autoimmune Disorders
442
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.

Synthesis and Regulation of Thyroid Hormones
4.6K
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...

Role of Skin in Vitamin D Synthesis
5.2K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
