概括

清细胞细胞癌 (ccRCC) 中的自然杀手 (NK) 细胞在晚期疾病中表现出功能障碍,瘤居民的表型,与生存率较差相关. 恢复NK细胞功能可能提供新的ccRCC疗法.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
基因组学就是基因组学.

背景情况:

自然杀手 (NK) 细胞对于清细胞脏细胞癌 (ccRCC) 的抗瘤免疫是至关重要的.
在ccRCC中NK细胞的特定表型,功能和临床相关性尚不清楚.

研究的目的:

研究ccRCC中NK细胞的表型和功能.
为了确定NK细胞子集与ccRCC患者的临床结果之间的关联.

主要方法:

单细胞RNA测序13个初级ccRCC瘤和配对的正常脏.
差异基因表达分析以识别NK细胞表型并导出基因签名.
流细胞测量以评估瘤透的NK细胞功能 (细胞因子的产生,细胞毒性).

主要成果:

确定了六个NK细胞子集;表达组织居住标记物和降低细胞毒性基因的"明亮样"子集被丰富了先进的ccRCC.
这种功能失调的NK细胞表型特征与独立ccRCC队列的整体存活率较差相关.
与其他NK细胞相比,瘤内 NK 细胞 (CD49a+CD9+) 的细胞毒性受损.

结论:

一种功能障碍的,瘤居住的NK细胞表型在晚期ccRCC中普遍存在,并且与患者存活率较差有关.
准NK细胞功能是ccRCC的潜在治疗策略.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
