肿瘤浸润淋巴细胞的卓越数据质量
概述
肿瘤浸润淋巴细胞(TILs)是一类从血液迁移到肿瘤中的免疫细胞。这些淋巴细胞,主要是T细胞,在机体对抗癌症的免疫反应中起着关键作用。TILs的存在、类型和活性可以为肿瘤的免疫原性以及患者的预后提供重要见解。

TILs是机体自然防御机制的一部分。最常见的类型包括细胞毒性T细胞(CD8+)、辅助T细胞(CD4+)、调节性T细胞(Tregs),有时还包括B细胞和自然杀伤细胞(NK细胞)。

TILs在临床上作为预后标志物、预测性生物标志物和治疗靶点具有重要意义。对TILs的分离和进一步表征对于评估不同肿瘤类型的治疗效果至关重要。然而,从肿瘤微环境(TME)中进行下游处理时常常会遇到挑战。在组织解离和分离后,TILs样本中常含有大量碎片和死细胞,因此需要严格清洗以去除污染物。
 从肿瘤微环境中分离TILs时,常见的关注点包括:
细胞回收率
数据质量
高背景信号
细胞聚集
高水平碎片
样本制备不一致性
工作流程低效

“The one thing which I didn't expect it here is that you reduce usage of antibody with roughly 50% and we've preserved signal and reproducibility.”

Jorgen Adolfsson,林雪平大学

Curiox如何提供帮助
     这些珍贵的TILs需要承受离心过程中产生的高机械压力,这可能进一步影响细胞的保留,Curiox技术提供了一种温和的替代方案,可以提高细胞回收和数据质量,特别是在初始细胞数量较低的样本中。

通过自动化细胞洗涤技术,可以确保减少碎片、获得更干净的细胞、改善分离效果并提高数据质量,从而改善TILs研究结果。
