In this context, Sheih et al.52 generated a single-cell transcriptome dataset of CD8+ CAR T cells isolated from the infusion product (IP), as well as from peripheral blood at the expansion peak after treatment (days 7–14; termed D12) of patients with relapsed and refractory non-Hodgkin lymphoma (GEO accession ID GSE125881). This evidence concerns the gene CD8A and non-Hodgkin lymphoma.
