Dynamic transcriptional immune landscape in response to NK-cell therapy combined with gemcitabine plus S-1 in advanced pancreatic cancer: a phase 1b/2 trial

Tem) in responders, characterized by increased expression of proinflammatory and effector molecules. Bulk T-cell receptor (TCR) Vβ repertoire sequencing of responders indicated potential T-cell clonal expansion, manifested as a greater abundance of large and hyperexpanded clonotypes. Our first-in-human trial demonstrated its safety and potentially preliminary efficacy, warranting further clinical evaluation. Multiomic profiling identified specific circulating NK and T-cell subsets potentially associated with clinical outcomes, providing novel insights into the dynamic transcriptional underpinnings of the immune landscape in response to NK cell-based therapy.
