概括
儿童急性淋巴细胞白血病的幸存者经历了加速的胸膜衰老,这种情况被称为胸膜免疫衰老. 这种通过T细胞受体切除循环 (TREC) 测量的加速衰老与幸存者的慢性疾病有关.
科学领域:
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
- 老年学是一门学科.
背景情况:
- 儿童急性淋巴细胞白血病 (cALL) 幸存者经常发展出通常在老年人身上出现的慢性疾病.
- 正常的衰老涉及器官功能障碍,包括免疫系统,一个称为免疫衰老的过程.
- 胸腺在免疫系统的发育和功能中起着至关重要的作用.
研究的目的:
- 为了研究cALL幸存者的胸膜免疫衰变.
- 为了确定胸膜老化是否与cALL幸存者的早期慢性疾病相关.
- 评估信号关节T细胞受体切除圈 (TREC) 作为胸膜衰老的生物标志物.
主要方法:
- 在PETALE研究中,cALL幸存者的队列接受了心血管和代谢评估.
- 在cALL幸存者和健康对照者中测量了TREC水平,TREC水平是胸膜免疫衰变的生物标志物.
- 在TREC水平,时间表年龄和临床参数之间进行了相关性分析.
主要成果:
- 与年龄相匹配的对照人群相比,cALL幸存者表现出加速的胸膜衰老 (免疫增强),TREC水平与年龄有很强的相关性.
- 这种加速衰老独立于诊断年龄和治疗,但在女性中更为明显.
- 胸膜衰老的增加与代谢综合征和细胞因子IL-6,IL-7和GM-CSF的水平升高有关.
结论:
- cALL及其治疗引发了快速的胸膜免疫增强,导致持续的加速胸膜衰老.
- 加快的胸膜免疫衰变是cALL生存的一个重要特征.
- 在癌症幸存者中,TREC水平作为一种有价值的生物标志物,用于监测胸膜衰老和健康状况.

01:23Cells of the Adaptive Immune Response
979
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

02:15Replicative Cell Senescence
3.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
