T cell receptor sequencing of HNSCC patient and healthy donor peripheral blood

This dataset comprises TCR-seq data from peripheral blood CD4+ and CD8+ T cells of head and neck squamous cell carcinoma (HNSCC) patients and healthy donors. Viable peripheral blood mononuclear cells (PBMCs) were sorted into CD45+CD3+CD4+ (CD4+ T cells) and CD45+CD3+CD8+ (CD8+ T cells) subsets, and RNA was isolated using the Qiagen AllPrep DNA/RNA Micro kit. TCR libraries were prepared with the SMART-Seq Human TCR-seq with UMIs kit (Takara Bio) and sequenced on an Illumina NovaSeq X Plus platform. This dataset includes samples from 27 tumor patients and five healthy donors (HDs). The study aims to investigate the phenotype, function, and spatial localization of T cells in HNSCC patients. This peripheral blood dataset focuses on characterizing circulating immune determinants of anti-HNSCC immunity and linking circulating T cell clones to those identified in patient-matched tumor scRNA-seq data. Overall design: CD4+ and CD8+ T cells were sorted from PBMCs of 27 HNSCC patients and 5 healthy donors (HDs). RNA was isolated and TCRs were sequenced using the SMART-Seq Human TCR-seq with UMIs kit from Takara Bio.
