概括

在乳头甲状腺癌 (PTC) 患者中,抗甲状腺素抗体 (TgAbs) 的存在与瘤复发的风险较低相关,可能是由于细胞免疫力增强.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
内分泌学在内分泌学.

背景情况:

乳头甲状腺癌 (PTC) 通常涉及T细胞透和抗甲状腺蛋白抗体 (TgAbs).
细胞免疫,TgAbs和PTC临床结果之间的相互作用仍在争论中.
了解这些因素对于预测患者的预后至关重要.

研究的目的:

调查TgAbs,瘤表位特异性T细胞和PTC患者的临床结果之间的相关性.
确定TgAbs是否影响PTC中的瘤复发率和T细胞反应.

主要方法:

研究了183名接受全甲状腺切除和131I切除治疗的PTC患者.
监测患者平均97个月的瘤复发和血清甲状腺蛋白 (Tg) 水平.
利用四聚体分析量化瘤表位特异性CD8+T细胞.

主要成果:

大多数PTC患者 (157/183) 没有出现瘤复发.
瘤复发 (14名患者) 与血清Tg水平≥2 ng/ml有关.
TgAb阳性患者 (27/183) 很少出现复发,Tg水平低于试验灵敏度,CD8+ T细胞数量较高.

结论:

存在TgAbs可能会对PTC患者的临床结果产生积极影响.

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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...

The Thyroid Gland

The Thyroid Gland

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...
