概括

在肝癌患者的手术瘤切除调节免疫细胞. 在手术后,调节性T (Treg) 细胞频率发生变化,这表明瘤切除后潜在的免疫系统恢复.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
肝病学肝病学是一种肝病学.

背景情况:

胆管癌 (CCA) 和肝细胞癌 (HCC) 是主要的肝癌.
调节性T细胞 (Treg) 在肝癌中通过免疫抑制至关重要.
了解切除后的免疫细胞动态对于治疗策略至关重要.

研究的目的:

在CCA和HCC患者中表征循环自然杀手 (NK) 细胞和T细胞子集.
评估手术切除瘤对外围血液免疫细胞恒温的影响.
研究瘤切除前后Treg细胞种群的变化.

主要方法:

在健康个体,CCA和HCC患者身上进行了全血检测.
使用流细胞计,细胞分类和qRT-PCR来分析免疫变化.
样品在手术前和手术后一个月被分析.

主要成果:

在CCA和HCC患者的预切割前,CD8+ Treg细胞增加和CD4+ Treg细胞减少.
在循环中的CD4+Treg细胞中没有观察到功能障碍.
切除后,外围CD4+Treg细胞的频率在CCA和HCC患者中显著增加.

结论:

手术切除瘤会影响肝癌患者的免疫调节.
移除瘤似乎恢复了周围血液NK和T细胞的稳态.
这些发现表明,手术干预对免疫微环境的潜在治疗益处.

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.

Liver Regeneration

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...
