Two PBMC samples — peak patient #21 and year 9.3 patient #21 — were analyzed. Both gene expression (GEX) and T cell receptor (TCR V(D)J) libraries were prepared and sequenced on the Illumina NextSeq 2000 system. Processed data include filtered count matrices and clonotype annotation tables for downstream reanalysis.2026/06/23GSE311890GSM9334027GSM9334019GSM9334014GSM933402330173311890Homo sapiens
