中文摘要

γδ T 细胞在肿瘤的固有免疫和适应性免疫中均发挥关键作用,但其在癌症中的存在及预后价值仍未得到充分探索。本研究利用 TRUST4 算法,对来自 33 种癌症类型的 11,000 份肿瘤样本中的 γδ T 细胞受体(γδ TCR)reads 进行了大规模分析。我们的研究结果揭示了 γδ TCR 克隆性和基因表达的广泛多样性,凸显了 γδ T 细胞作为多种癌症预后生物标志物的潜力。我们进一步证明了来自标准 RNA 测序(RNA-seq)数据的 TCR gamma(TRG)和 delta(TRD)基因表达的实用性。这一综合性数据集为推进 γδ T 细胞研究提供了宝贵资源,对改进免疫治疗方法或替代治疗策略具有重要意义。此外,我们的集中式数据库支持针对 γδ T 细胞治疗意义的转化研究。

Gamma-delta T cells (γδ T cells) play a crucial role in both innate and adaptive immunity within tumors, yet their presence and prognostic value in cancer remain underexplored.

This study presents a large-scale analysis of γδ T cell receptor (γδ TCR) reads from 11,000 tumor samples spanning 33 cancer types, utilizing the TRUST4 algorithm.

Our findings reveal extensive diversity in γδ TCR clonality and gene expression, underscoring the potential of γδ T cells as prognostic biomarkers in various cancers.

We further demonstrate the utility of TCR gamma (TRG) and delta (TRD) gene expression from standard RNA-sequencing (RNA-seq) data. This comprehensive dataset offers a valuable resource for advancing γδ T cell research, with implications for enhanced immunotherapy approaches or alternative therapeutic strategies.

Additionally, our centralized database supports translational research into the therapeutic significance of γδ T cells.
