概括
癌,或肌肉损失,在CAR-T细胞治疗后很常见,并且与生存率低下有关. 早期检测和干预可以改善接受这种治疗的癌症患者的治疗结果.
科学领域:
- 在瘤学瘤学.
- 代谢过程中的代谢.
- 免疫治疗是一种免疫疗法.
背景情况:
- 萨科佩尼亚是癌症缓冲症的一个关键特征.
- 化学抗原受体 (CAR) T细胞疗法可以诱导炎症状态,可能恶化.
- 卡尔T细胞治疗,肉症和代谢变化之间的相互作用尚未得到充分理解.
研究的目的:
- 在接受CAR T细胞治疗的大型B细胞淋巴瘤患者中调查肉类症的患病率.
- 为了检查基线萨尔科佩尼亚,治疗后骨肌损失和患者存活率之间的关系.
- 探索与CAR T细胞疗法相关的代谢变化及其与肌肉质量变化的相关性.
主要方法:
- 骨肌肉指数 (SMI) 根据临床图像测量了83名大B细胞淋巴瘤患者在基线和治疗后30和90天的临床图像.
- 在治疗的前4周内,对57名患者进行了血清代谢分析.
- 进行了统计分析,以关联sarcopenia,肌肉损失,代谢概况和临床结果,包括整体存活率 (OS) 和非复发死亡率 (NRM).
主要成果:
- 超过一半的患者出现了基线的肉症,这与中位数的短寿命 (10.5个月与34.3个月,P=0.006) 和增加的NRM显著相关.
- 大约三分之一的患者在CAR T细胞治疗后的30天内出现了超过10%的骨肌肉损失,这与较高的瘤负担和神经毒性有关.
- 代谢分析显示,纯素代谢物 (1至2周) 早期增加,其次是高甘油水平 (3至4周),酸显示最高的折叠增加.
结论:
- 骨肌肉损失是CAR T细胞治疗的常见并发症,与脂肪酸代谢有关.
- 基线肉类预测在接受CAR T细胞治疗的患者中耐受性差和生存率降低.
- 专注于饮食和运动干预的未来研究有理由潜在地提高CAR T细胞治疗结果.

Cross-bridge Cycle
115.9K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Satellite Stem Cells and Muscular Dystrophy
1.9K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
