概括

这项研究表明,人乳头瘤病毒 (HPV) 可能通过分子模仿在甲状腺眼病 (TED) 中发挥作用. 在TED患者中发现HPV18 L1 IgG抗体升高,表明潜在的自身免疫触发因素.

科学领域:

免疫学免疫学免疫学
病毒学病毒学
眼科医生眼科眼科

背景情况:

甲状腺眼病 (TED) 是一种自身免疫性疾病,导致轨道炎症和组织重塑.
它的致病性尚未完全理解,但涉及针对TSHR和IGF-1R的自身抗体.
病毒感染在TED的潜在作用尚未被探索.

研究的目的:

调查病毒感染在甲状腺眼病 (TED) 病原发生过程中的潜在参与.
探索病毒蛋白和TED自身抗原之间的分子模仿.

主要方法:

NCBI BLAST用于将人类TSHR和IGF-1R蛋白与病毒蛋白质组进行比较.
酶相关免疫试验 (ELISA) 量化了TED患者和对照者的轨道脂肪组织中的抗病毒抗体标位.
分析了人口统计和临床数据.

主要成果:

同性分析揭示了TSHR/IGF-1R和病毒蛋白之间的保留动机,特别是HPV18 L1囊蛋白.
与对照人群相比,ELISA显示TED患者 (活跃和慢性) 的HPV18 L1 IgG抗体标位显著更高.
增加的HPV18 L1 IgG标位与甲状腺激素水平或teprotumumab治疗无关,这表明对HPV有直接的免疫反应.

结论:

这项研究提供了第一个分子证据,将人乳头瘤病毒 (HPV) 与甲状腺眼病 (TED) 联系起来.
HPV囊蛋白和TED自身抗原之间的分子模拟表明了潜在的自身免疫机制.
这些发现为了解TED的病原体和开发向治疗开辟了新的途径.

Synthesis and Regulation of Thyroid Hormones

Synthesis and Regulation of Thyroid Hormones

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...

Functions of Thyroid Hormones

Functions of Thyroid Hormones

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...

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
