概括
三级淋巴状结构 (TLS) 密度在非小细胞肺癌 (NSCLC) 区域之间有所不同. 侵入性边缘中较高的早期TLS (E-TLS) 与更差的预后相关,表明NSCLC进展中的复杂免疫相互作用.
科学领域:
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 三级淋巴体结构 (TLS) 是在瘤免疫微环境 (TIME) 内的有组织的免疫细胞聚合物.
- TLS与各种癌症的抗瘤免疫有关,但它们在非小细胞肺癌 (NSCLC) 的区域分布仍未得到充分研究.
- 以前的研究表明,TLS存在于不同成熟度的瘤内 (IT),侵入边缘 (IM) 和瘤周边 (PT) 区域.
研究的目的:
- 调查NSCLC在不同地区 (IT,IM,PT) 的TLS密度和分布.
- 分析TLS特征 (密度,成熟度) 与临床病理特征之间的相关性.
- 评估TLS的预后价值,并为NSCLC患者的存活率构建预测性名录.
主要方法:
- 免疫组织化学 (IHC) 染色是在82名NSCLC患者样本上进行的.
- TLS被分类为早期/初级 (E-TLS) 或二级/毛囊性 (F-TLS),并在IT,IM和PT区域量化.
- 分析了临床病理学数据和整体存活率 (OS),并开发了用于生存预测的诺姆图.
主要成果:
- 与IM和PT地区相比,IT地区的TLS密度和F-TLS比例明显高于IT地区.
- 较低的TLS密度,特别是IM区域的E-TLS,与更好的预后有关.
- 免疫细胞群 (B细胞,T细胞,巨细胞) 在IM区域富含,与E-TLS密度相关.
结论:
- TLS的密度和位置,特别是侵袭边缘的E-TLS,是NSCLC的关键预后指标.
- 在IM中增加的E-TLS密度可能与更糟糕的预后有关,可能是由于免疫细胞活动的抑制.
- 这项研究强调了TLS分布和免疫细胞透在NSCLC瘤微环境中的预后意义.

Lymphoid Cells and Tissues
3.4K
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
